* Make incremental mode work with partitionable arraysDoug Ledford2008-10-291-1/+1
| | | | | | | | | | | | | | | | | | | | There were multiple problems with incremental mode and partitionable arrays. Change the logic to pay more attention to what it finds in mdadm.conf when setting up incremental arrays. Modify is_standard to differentiate between a required partitioned name format and an optionally partitioned named format. Modify open_mddev() to know about change to is_standard. Make Incremental differentiate between create default autof setting, command line autof setting, and array specific autof setting, with order of preference being command line, conf file, default. Disable the homehost test in the event there is no match for an array so we can hotplug new arrays into a running machine without them having to exist in mdadm.conf first (a random array number will be picked for the hot plugged array). Honor any name from mdadm.conf that matches the UUID of a device, not just standard names. Verify that the array name as matched in mdadm.conf allows the requested mode of operation and reject attempts to start non-partitionable arrays as partitioned and vice versa.

* Fix support for --update=swapsuperNeil Brown2008-05-151-1/+2

* Unify code into find_free_devnum.Neil Brown2008-05-051-0/+37
| | | | | Two places have code to find a free md device number. Make this a subroutine.

* Use sysfs info for metadata version info in Detail and elsewhere.Neil Brown2007-12-141-1/+3
|
* Replace sysarray with mdinfoNeil Brown2007-12-141-3/+3
| | | | | Sure, mdinfo is bigger, but having a uniform structure for lots of things will make life easier.
* Find super from fd on an array.Neil Brown2007-12-141-11/+45
| | | | | We used to use the major/minor numbers, but that isn't sufficient any more, so pass the fd, and possibly check 'text' version.
* Drop the superblock arg from all metadata methods.Neil Brown2007-12-141-11/+16
| | | | It is now in the 'supertype'
* Add 'supertype' arg to almost all metadata methods.Neil Brown2007-12-141-3/+3
| | | | The 'superblock' will be moved into this structure soon.
* Allow metadata handlers to free their own superblock.Neil Brown2007-12-141-1/+1
| | | | | | As the metadata handler allocates the superblock, it should free it too. DDF will have a more complex 'superblock' which needs more complex freeing.
* Remove spaces/tabs from ends of lines.Neil Brown2007-12-141-33/+30

* Remove bogus add_dev definition.Neil Brown2007-05-081-4/+0
| | | | | If nether ftw nor nftw are available, add_dev gets defined twice. Fix that...
* Add new mode: --incrementalNeil Brown2006-12-211-0/+8
| | | | | --incremental allows arrays to be assembled one device at a time. This is expected to be used with udev.
* Centralise code for copying uuidNeil Brown2006-12-141-0/+19
| | | | Rather than opencoding the byteswap all the time.
* Central calls to ioctl BLKGETSIZENeil Brown2006-12-141-0/+22
| | | | Instead of opencoding the same thing everywhere.
* Give useful message if raid4/5/6 cannot be started because it is not clean ↵Neil Brown2006-12-141-3/+9
| | | | and is also degraded.
* Fix bugs related to raid10 and the new offset layout.Neil Brown2006-10-191-1/+1
| | | | | Need to mask of bits above the bottom 16 when calculating number of copies.
* Mdassemble improvementsLuca Berra2006-10-161-0/+6
| | | | | | | | | From: Luca Berra <bluca@comedia.it> - Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele stacked arrays. - Allow mdassemble, when run a second time, to mark all arrays as writable. This is useful if they are started read-only as is best at boot-time.
* Don't #include blkpg.hNeil Brown2006-10-161-1/+33
| | | | Just include the content directly. It is safer.
* Remove partitions from components of an md arrayNeil Brown2006-10-131-0/+20
| | | | They do nothing but cause confusion.
* Improve ftw handling.Neil Brown2006-06-261-28/+22
| | | | | | | If not 'ftw' is available, still allow openning of devices by dev number. More recent version of uclibc support nftw, so add support to check for that.
* Stop map_dev from returning [0:0]Neil Brown2006-06-201-6/+7
| | | | | We sometimes need the NULL when major==minor==0. So make sure all callers of map_dev can cope with NULL.
* Fix memory leak in monitor modeNeil Brown2006-06-161-0/+13
| | | | | | | When rescanning /dev, we didn't free the old list. Also don't search for device with a number of 0,0 Signed-off-by: Neil Brown <neilb@suse.de>

* Make scanning of /dev work even if it is a symlinkNeil Brown2006-03-271-1/+8
| | | | | | | | We generally don't want to follow symlinks in /dev, but if /dev itself is a symlink, we want to follow it. So nftw needs a bit of help. Signed-off-by: Neil Brown <neilb@suse.de>
