* New API: guestfs_nr_devicesRichard W.M. Jones2012-06-291-1/+1
| | | | | | This returns the number of whole block devices added. It is usually simpler to call this than to list the devices and count them, which is what we do in some places in the current codebase.
* New API: device-index.Richard W.M. Jones2012-06-131-1/+1
| | | | | | This returns the index of the device, eg. /dev/sdb => 1. Or you can think of it as the order that the device was added, or the index of the device in guestfs_list_devices.
* New API: fstrim - allow filesystem trim.Richard W.M. Jones2012-06-121-1/+1
|
* New API: filesystem-available: tests for filesystem availability.Richard W.M. Jones2012-06-091-1/+1
| | | | | This also creates an internal filesystem_available function within the daemon.
* NEW API: add new api btrfs-fsckWanlong Gao2012-05-151-1/+1
| | | | | | | | | Add the new API btrfs-fsck to check the btrfs filesystem. Btrfs is currently under heavy development, and not suitable for any uses other than benchmarking and review. But it'll be useful in the near future. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* New API: add new api btrfs-set-seeding to enable or disable seeding.Wanlong Gao2012-05-141-1/+1
| | | | | | | Add the new API btrfs-set-seeding to support the seeding-device feature for btrfs. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* New btrfs APIs.Richard W.M. Jones2012-04-251-1/+1
| | | | | | | | | | | | | | | | Bind the easy parts of the 'btrfs' program. The new APIs are: btrfs-device-add: add devices to a btrfs filesystem btrfs-device-delete: remove devices from a btrfs filesystem btrfs-filesystem-sync: sync a btrfs filesystem btrfs-filesystem-balance: balance a btrfs filesystem btrfs-subvolume-create: create a btrfs snapshot btrfs-subvolume-delete: delete a btrfs snapshot btrfs-subvolume-list: list btrfs snapshots and subvolumes btrfs-subvolume-set-default: set default btrfs subvolume btrfs-subvolume-snapshot: create a writable btrfs snapshot
* New APIs for reading and writing ext2 file attributes and file generation.Richard W.M. Jones2012-04-131-1/+1
| | | | | | | | | | | | The new APIs are: get-e2attrs: List ext2 file attributes of a file. set-e2attrs: Set or clear ext2 file attributes of a file. get-e2generation: Get ext2 file generation of a file. set-e2generation: Set ext2 file generation of a file. These are implemented using the lsattr and chattr programs from e2fsprogs.
* New API: mkfs-btrfs for creating btrfs filesystems (RHBZ#807905).Richard W.M. Jones2012-04-021-1/+1
| | | | This allows all parameters from btrfs to be accessed.
* New API: md-stat.Richard W.M. Jones2012-03-201-1/+1
| | | | | This returns information about the underlying devices of an MD (software RAID) device.
* New API: vgmeta: Download volume group metadata.Richard W.M. Jones2012-03-171-1/+1
|
* New APIs: isoinfo and isoinfo-device.Richard W.M. Jones2012-03-161-1/+1
| | | | | Get ISO primary volume descriptor information for either ISO devices or ISO files.
* New API: lvcreate-free: Create logical volume as % of free space.Richard W.M. Jones2012-03-151-1/+1
|
* New API: zero_free_space: zero free space in a filesystem.Richard W.M. Jones2012-03-151-1/+1
| | | | | | | | | | | | | | Add an API for doing what virt-sparsify was doing: freeing up free space in a filesystem. The current implementation is simple-minded: we create a file, fill it with zeroes until we run out of space, then delete the file. However the description leaves it open to do a better implementation, eg. using sparsification support that is currently being worked on in ext4 and qemu. The implementation also sends progress notifications, which is an advantage over the old 'dd' method.
* New API: set-label, for setting a label on any filesystem.Richard W.M. Jones2012-02-271-1/+1
| | | | | | Currently only ext2/3/4 and (newly) NTFS are supported. This change also deprecates set-e2label.
* New APIs: ntfsclone-in, ntfsclone-out.Richard W.M. Jones2012-02-271-1/+1
|
* New API: ntfsfix for fixing problems on NTFS.Richard W.M. Jones2012-02-271-1/+1
| | | | Note this is not a "chkdsk" equivalent tool.
* NEW API: add a new api wipefsWanlong Gao2012-02-101-1/+1
| | | | | | | Add the new api wipefs to erase the filesystem signatures on a device but now erase any data. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* New API: llz: This runs ls -laZ and is useful for showing SELinux contexts.Richard W.M. Jones2012-02-091-1/+1
|
* NEW API: add a new api e2fsckWanlong Gao2012-01-131-1/+1
| | | | | | | | | | | | | | m: Wanlong Gao <gaowanlong@cn.fujitsu.com> Add a new api e2fsck with two options: correct: same as '-p' option of e2fsck forceall: same as '-y' option of e2fsck Thanks for Rich's idea. v1->v2: use optargs_bitmask v2->v3: change the optargs_bitmask check Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* NEW API: add blkid command to print the attributes of the deviceWanlong Gao2011-12-031-1/+1
| | | | | | | | | | | | A NEW API blkid. It can print the device attributes. Use it after list-devices, we can list ower devices and the attributes of each device. Use it like: blkid <device> It's should be a usefull function. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* New API: md-stop for stopping MD devicesWanlong Gao2011-11-241-1/+1
| | | | | | | | This API is used to stop a md device. When we want to move a device to another md array, we should stop the md device which contained this device first. Signed-off-by: Wanlong Gao <gaowanlong@cn.fujitsu.com>
* New API: mdadm-detail.Matthew Booth2011-11-171-1/+1
|
* New API: list-md-devices.Matthew Booth2011-11-111-1/+1
| | | | | | | Return a list of Linux MD devices detected in the guest. This API complements list_devices, list_partitions, list_lvs and list_dm_devices.
* New API: mdadm-create for creating MD devices.Richard W.M. Jones2011-11-111-1/+1
|
* New API: Bind the tune2fs command.Richard W.M. Jones2011-11-111-1/+1
| | | | | | | | | | | | | Previously we bound the 'tune2fs -l' command so that we could list out the tunables of an ext2/3/4 filesystem. Also commands like set_e2label and set_e2uuid used tune2fs. This commit binds many of the tunables that can be set using tune2fs. The coverage is not complete, but we can add more later because this uses optional parameters so the call is extensible without breaking ABI. The current change gives us enough for using libguestfs within OpenStack.
* New APIs: copy-{file,device}-to-{file,device}.Richard W.M. Jones2011-10-261-1/+1
| | | | | | | | | | | The four new APIs: guestfs_copy_device_to_device, guestfs_copy_device_to_file, guestfs_copy_file_to_device, and guestfs_copy_file_to_file let you copy from a source to a destination, between files and devices, optionally allowing source and destination offsets and size to be specified.
* New API: part-to-partnumRichard W.M. Jones2011-10-251-1/+1
| | | | | | This converts a partition device name (eg. /dev/sda1) to a partition number (eg. 1). This is useful in conjunction with the parted APIs that mostly take a disk device + partnum.
* New APIs: compress-out, compress-device-out.Richard W.M. Jones2011-09-281-1/+1
| | | | | | | | | | | | | | | | | These APIs let you copy compressed files or devices out from the disk image. Compression is useful for large images which are mostly zeroes. We cannot currently do sparseness detection, and compression gives us a form of zero detection for free. Example usage: $ guestfish --ro -a /dev/vg_pin/F16x64 -i \ compress-out gzip /etc/passwd /tmp/passwd.gz $ file -z /tmp/passwd.gz /tmp/passwd.gz: ASCII text (gzip compressed data, was "passwd", from Unix, last modified: Sun Aug 28 14:40:46 2011)
* New API: write-appendRichard W.M. Jones2011-07-141-1/+1
| | | | Append content to the end of a file.
* New API: btrfs-filesystem-resize (RHBZ#721160).Richard W.M. Jones2011-07-141-1/+1
| | | | This resizes a btrfs filesystem.
* New API: ntfsresize-opts (RHBZ#685009).Richard W.M. Jones2011-07-121-1/+1
| | | | | | This is a more comprehensive fix for RHBZ#685009. Add a new API which allows the --force flag to be passed, allowing multiple NTFS resize operations in a single session.
* New API: list-dm-devices (RHBZ#688062).Richard W.M. Jones2011-07-121-1/+1
| | | | List device mapper devices.
* New API: mount-9p lets you mount 9p filesystems (RHBZ#714981).Richard W.M. Jones2011-06-221-1/+1
| | | | The updated patch makes 'options' into an optional parameter.
* New API: list-9p lists 9p filesystem mount tags (RHBZ#714981).Richard W.M. Jones2011-06-221-1/+1
|
* New APIs: is-zero and is-zero-device, to test if file or device is all zeroes.Richard W.M. Jones2011-05-171-1/+1
|
* Add a new internal-autosync API to perform autosync.Richard W.M. Jones2011-01-281-1/+1
| | | | | | | | | Instead of explicitly calling umount-all; sync, we add a daemon function called internal-autosync which does the same. Apart from slightly simplifying the process of closing the handle, the main advantage is we can modify the daemon for the standalone case so that internal-autosync does not do the umount-all operation.
* New API: resize2fs-M to resize ext2/3/4 to minimum size.Nikita A Menkovich2011-01-141-1/+1
|
* New APIs: getxattr and lgetxattr to get single extended attributes.Richard W.M. Jones2010-12-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These APIs are essentially required to work around a problem with ntfs-3g. This filesystem (or FUSE?) does not list all extended attributes of a file when you call listxattr(2). However if you know the name of an extended attribute, you can retrieve it directly using getxattr(2). The current APIs (getxattrs etc) are simple to use, but they don't work if we can't list out the extended attributes (ie. by calling listxattr(2)). Example using the new APIs on an ntfs-3g filesystem: ><fs> lgetxattr "/Documents and Settings" system.ntfs_attrib | hexdump -C 00000000 16 24 00 00 |.$..| 00000004 ><fs> lgetxattr "/Documents and Settings" system.ntfs_reparse_data | hexdump -C 00000000 03 00 00 a0 34 00 00 00 00 00 18 00 1a 00 10 00 |....4...........| 00000010 5c 00 3f 00 3f 00 5c 00 43 00 3a 00 5c 00 55 00 |\.?.?.\.C.:.\.U.| 00000020 73 00 65 00 72 00 73 00 00 00 43 00 3a 00 5c 00 |s.e.r.s...C.:.\.| 00000030 55 00 73 00 65 00 72 00 73 00 00 00 |U.s.e.r.s...| 0000003c ><fs> getxattr "/Documents and Settings" system.ntfs_reparse_data | hexdump -C libguestfs: error: getxattr: getxattr: No such file or directory ><fs> getxattr "/Documents and Settings" system.ntfs_attrib | hexdump -C libguestfs: error: getxattr: getxattr: No such file or directory ><fs> lgetxattr "/Documents and Settings" system.ntfs_attrib | hexdump -C 00000000 16 24 00 00 |.$..| 00000004 ><fs> getxattr "/Users" system.ntfs_attrib | hexdump -C 00000000 11 00 00 00 |....| 00000004
* New API: mkfs_opts, mkfs with optional arguments.Richard W.M. Jones2010-12-021-1/+1
| | | | | | This is an extensible version of 'mkfs' which supports optional arguments. There is now no need for 'mkfs_b' since you should use 'mkfs_opts' with the optional 'blocksize' argument instead.
* New API: lvm-canonical-lv-name: make LV name canonical.Richard W.M. Jones2010-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When logical volume names appear in places like /etc/fstab files they can have the form "/dev/mapper/foo-bar". This function takes such names and makes them canonical. Note that this operation cannot be performed using the current API, because 'guestfs_stat' does not work on device names, and we don't really want to make a 'stat-device' call since that exposes too much non-useful detail about the appliance. With this patch you can do this: ><fs> debug ll /dev/mapper total 8 drwxrwxr-x 2 root root 4096 Oct 25 12:51 . drwxr-xr-x 16 root root 4096 Oct 25 12:51 .. crw------- 1 root root 10, 62 Oct 25 12:51 control lrwxrwxrwx 1 root root 7 Oct 25 12:51 vg_f13x64-lv_root -> ../dm-0 lrwxrwxrwx 1 root root 7 Oct 25 12:51 vg_f13x64-lv_swap -> ../dm-1 ><fs> lvm-canonical-lv-name /dev/mapper/vg_f13x64-lv_root /dev/vg_f13x64/lv_root ><fs> lvm-canonical-lv-name /dev/mapper/vg_f13x64-lv_swap /dev/vg_f13x64/lv_swap ><fs> lvm-canonical-lv-name /dev/mapper/foo libguestfs: error: lvm_canonical_lv_name: lvm_canonical_lv_name_stub: /dev/mapper/foo: No such file or directory ><fs> lvm-canonical-lv-name /dev/mapper/control libguestfs: error: lvm_canonical_lv_name: /dev/mapper/control: not a logical volume ><fs> lvm-canonical-lv-name /dev/vg_f13x64/lv_root /dev/vg_f13x64/lv_root
* New API: pread-device, partial read for devices.Richard W.M. Jones2010-09-271-1/+1
|
* New API: pwrite-deviceRichard W.M. Jones2010-09-261-1/+1
| | | | | This is the same as the existing 'pwrite' API call, but allows you to write to a device.
* New APIs: upload-offset and download-offsetRichard W.M. Jones2010-09-211-1/+1
| | | | | These APIs allow you to efficiently write and read parts of files or devices.
* New API: part-to-dev: Convert partition name to device name.Richard Jones2010-09-151-1/+1
| | | | | This adds a formal API for going from a partition to the containing device, eg. /dev/sda1 -> /dev/sda
* New APIs: is-chardev, is-blockdev, is-fifo, is-symlink, is-socketRichard Jones2010-09-091-1/+1
| | | | These complement the existing is-file and is-dir APIs.
* New APIs: findfs-label and findfs-uuidRichard Jones2010-08-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | These two calls wrap up the /sbin/findfs command, allowing you to find a filesystem by only knowing its label or UUID. This is especially useful when resolving LABEL=... or UUID=... entries in /etc/fstab. Sample guestfish session: ><fs> vfs-uuid /dev/vda1 277dd61c-bf34-4253-a8dc-df500a05e7df ><fs> findfs-uuid 277dd61c-bf34-4253-a8dc-df500a05e7df /dev/vda1 ><fs> vfs-label /dev/vda1 /boot ><fs> findfs-label /boot /dev/vda1 ><fs> vfs-uuid /dev/VolGroup00/LogVol00 40ce7c36-82ce-4a12-a99d-48f5e054162c ><fs> findfs-uuid 40ce7c36-82ce-4a12-a99d-48f5e054162c /dev/mapper/VolGroup00-LogVol00 ><fs> findfs-uuid 12345678 libguestfs: error: findfs_uuid: findfs: unable to resolve 'UUID=12345678'
* New API: is-lv: check if a block device is a logical volume (RHBZ#619793)Richard Jones2010-07-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, guestfs_is_lv (g, device), which returns true iff the named device is an LVM2 logical volume. A sample guestfish session: ><fs> lvs /dev/vg_f13x64/lv_root /dev/vg_f13x64/lv_swap ><fs> list-devices /dev/vda ><fs> list-partitions /dev/vda1 /dev/vda2 ><fs> is-lv /dev/vg_f13x64/lv_root true ><fs> is-lv /dev/vg_f13x64/lv_swap true ><fs> is-lv /dev/vda false ><fs> is-lv /dev/vda1 false ><fs> is-lv /dev/vda2 false
* New APIs: Support for creating LUKS and managing keys.Richard Jones2010-07-221-1/+1
| | | | | | | | | | | | | | | | | | | This commit adds four APIs for creating new LUKS devices and key management. These are: luks_format Format a LUKS device with the default cipher. luks_format_cipher Format with a chosen cipher. luks_add_key Add another key to an existing device. luks_kill_slot Delete a key from an existing device. This enables all the significant functionality of the cryptsetup luks* commands. Note that you can obtain the UUID of a LUKS device already by using vfs-uuid. This also includes a regression test covering all the LUKS functions.
* New APIs: Support for opening LUKS-encrypted disks.Richard Jones2010-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for opening LUKS-encrypted disks, via three new APIs: luks_open: Create a mapping for an encrypted disk. luks_open_ro: Same, but read-only mapping. luks_close: Close a mapping. A typical guestfish session using this functionality looks like this: $ guestfish --ro -a encrypted.img ><fs> run ><fs> list-devices /dev/vda ><fs> list-partitions /dev/vda1 /dev/vda2 ><fs> vfs-type /dev/vda2 crypto_LUKS ><fs> luks-open /dev/vda2 luksdev Enter key or passphrase ("key"): ><fs> vgscan ><fs> vg-activate-all true ><fs> pvs /dev/dm-0 ><fs> vgs vg_f13x64encrypted ><fs> lvs /dev/vg_f13x64encrypted/lv_root /dev/vg_f13x64encrypted/lv_swap ><fs> mount /dev/vg_f13x64encrypted/lv_root / ><fs> ll / total 132 dr-xr-xr-x. 24 root root 4096 Jul 21 12:01 . dr-xr-xr-x 20 root root 0 Jul 21 20:06 .. drwx------. 3 root root 4096 Jul 21 11:59 .dbus drwx------. 2 root root 4096 Jul 21 12:00 .pulse -rw-------. 1 root root 256 Jul 21 12:00 .pulse-cookie dr-xr-xr-x. 2 root root 4096 May 13 03:03 bin NOT included in this patch: - An easier way to use this from guestfish. - Ability to create LUKS devices. - Ability to change LUKS keys on existing devices. - Direct access to the /dev/mapper device (eg. if it contains anything apart from VGs).
