| * | map: rebuild map if it doesn't exist.NeilBrown2008-12-182-47/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible for some arrays to be created e.g. by initrd, and so not get mentioned in /var/run/mdadm/map. As "-I" depends on things being listed in 'map', we create it by scanning all devices if it doesn't exist. Signed-off-by: NeilBrown <neilb@suse.de>
| * | Assemble: set stripe_cache_size properly when restarting a reshape.NeilBrown2008-12-181-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | Reshape with large chunk size can require a large stripe_cache. We make this work when starting the reshape but not when restarting at assemble time. So fix that. Signed-off-by: NeilBrown <neilb@suse.de>
| * | Assemble: don't assume array is 'clean' unless all devices think it is.NeilBrown2008-12-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This is only significant for --assemble --force where some old devices might be included into the array. If anything looks like it isn't clean, the kernel will not allow a degraded array to be started. Signed-off-by: NeilBrown <neilb@suse.de>
| * | Kill: Don't use O_EXCL when --force is used.NeilBrown2008-12-181-1/+1
| | | | | | | | | | | | | | | | | | | | | We really want --zero-super --force to zero the superblock in all situations. So don't open with O_EXCL - trust the user. Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolves issues like: mdadm -Ss mdadm: unable to open /dev/md/r1: No such file or directory ...where /dev/md/r1 points to a removed device. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* | | Create: support autolayout when creating in a DDFNeilBrown2008-12-044-47/+205
| | | | | | | | | | | | | | | | | | | | | | | | | | | If, when creating an array, a signal target device is given which is a container, then allow the metadata handler to choose which devices to use. This is currently only supported for DDF. Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | | | | | | | | | That way it is the same a *freesize, and generally less confusing. Signed-off-by: NeilBrown <neilb@suse.de>

| * Assemble: allow --force to work even when event counts are 0.NeilBrown2008-11-271-2/+0
| | | | | | | | | | | | | | | | | | | | If any superblocks in a confused array had an event count of 0, "mdadm -Af" would not update the event counts to assemble the array. I don't remember why that text is there, and it has caused at least one situation to be difficult to recover from. So remove the test. --force means --force! Signed-off-by: NeilBrown <neilb@suse.de>
* | Assemble: wait for device to appear via udevNeilBrown2008-11-271-0/+1
| | | | | | | | | | | | | | Use the new "wait_for" function to make sure udev has created the device before completion the 'assemble'. Signed-off-by: NeilBrown <neilb@suse.de>
* | imsm: fix metadata reservationDan Williams2008-11-271-0/+7
| | | | | | | | | | | | | | | | | | | | 1/ When truncating the space reserved for the metadata round down to an even numbered sector count to avoid an off-by-one error when sysfs_add_disk rounds up. 2/ Set the current metadata parameter block size as a floor. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
* | Tidy error messages for add_to_super failure.NeilBrown2008-11-273-7/+10
| | | | | | | | | | | | | | Make sure every failure from add_to_super prints a suitable error message, and then don't print any error in the caller. Signed-off-by: NeilBrown <neilb@suse.de>
* | allow add_to_super to return errorsDan Williams2008-11-277-18/+35

* | Support --wait-clean --scanDan Williams2008-11-272-8/+17
| | | | | | | | | | | | | | Its cumbersome to determine which devices to wait for in a system shutdown script, so hook up --scan. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

* | Assemble: don't auto-assemble if any arrays are listed in mdadm.confNeilBrown2008-11-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Auto-assembly and planned assembly don't really work well together, it can be confusing. In particular in mkinitrd or similar creates an mdadm.conf to assemble a particular array, we shouldn't go assembling any other arrays as well. If you want auto assembly, you need to give mdadm a config file with no ARRAY lines. mdadm -Ascpartitions can do this. Signed-off-by: NeilBrown <neilb@suse.de>
* | mdmon: pass symbolic name to mdmon instead of device name.NeilBrown2008-11-204-9/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that names in /dev are usually created (eventually) by udev, it isn't really safe to rely in finding a name in /dev to pass to mdmon to identify which array to monitor. And it isn't really necessary to have a name in /dev. So just pass the symbolic name, e.g. md127 or md123. Change util.c to pass that name, and change mdmon to process the name sensibly.

* | Stop: drop any partitions that may be associated with an array when stopping it.NeilBrown2008-11-041-1/+4
| | | | | | | | | | | | | | Not all kernels automatically discard partitions when the array is stopped, so call the RRPART ioctl to force it. Signed-off-by: NeilBrown <neilb@suse.de>
* | Wait for name to appear after create/assemble etc.NeilBrown2008-11-046-3/+23
| | | | | | | | | | | | | | We don't really want mdadm to exit until udev has created the names in /dev. So wait. Signed-off-by: NeilBrown <neilb@suse.de>
* | mapfile: validate entries before they are returned.NeilBrown2008-11-042-10/+30
| | | | | | | | | | | | | | It is possible for the mapfile to become wrong, and that gets very confusing. So validate entries before returning them. Signed-off-by: NeilBrown <neilb@suse.de>

* | test: always start with a clean slate.NeilBrown2008-11-041-0/+2
| | | | | | | | | | | | | | To avoid confusion with old array, also zero superblocks before starting a test. Signed-off-by: NeilBrown <neilb@suse.de>
* | Incrmental: cope with udev slowness and errors in map file.NeilBrown2008-11-041-3/+10
| | | | | | | | | | | | | | | | | | | | If udev hasn't created the array yet, we might still want to open it. So open directly by major:minor. Also, of array in map file doesn't appear to exist, do use the name associated with it. Signed-off-by: NeilBrown <neilb@suse.de>
* | Abort sysfs_read early if no device found.NeilBrown2008-11-041-0/+5
| | | | | | | | | | | | | | sysfs_read currently tried to look in sysfs even in no valid sys_name was found. Don't to that. Signed-off-by: NeilBrown <neilb@suse.de>
* | mdopen: only let numeric name set minor number if it doesn't cause a conflict.NeilBrown2008-11-041-1/+4
| | | | | | | | | | | | | | So if the array with minor number matching the name of a new array already exists, just assemble with a different minor number. Signed-off-by: NeilBrown <neilb@suse.de>

* | test: make sure udev isn't opening a device before closing it.NeilBrown2008-11-041-0/+3
| | | | | | | | | | | | | | As we open and close so quickly, udev might still have the device open. so call udevsettle before stopping an array during testing. Signed-off-by: NeilBrown <neilb@suse.de>
