* Fix autoassemble for stack arrays.Neil Brown2008-05-201-2/+4
| | | | | | | | If you have stacked arrays, then mdadm -As --homehost=fred should work but doesn't. It gets into an infinite loop! So write some tests, and fix the bugs.

* Reject '--bitmap none' for build and create.Neil Brown2007-07-231-1/+7
| | | | | We don't want to create a file called 'none', and it isn't needed, so just reject it.
* Allow "--write-behind=" to be done in grow mode.Ian Dall2007-07-091-0/+1
| | | | | | | | | From: Ian Dall <ian@beware.dropbear.id.au> I have a small patch to mdadm which allows the write-behind amount to be set a array grow time (instead of currently only at grow or create time). I have tested this fairly extensively on some arrays built out of loop back devices, and once on a real live array.
* Fix parsing of "-a" in various contexts.Doug Ledford2007-07-091-3/+5
| | | | | | | | | | | | From: Doug Ledford <dledford@redhat.com> This one fixes a bug where once manage mode is set, the -a short option is no longer parsed correctly (true of grow mode as well). This happens because when you switch the short opts to the bitmap_auto version, it specifies that the argument must follow a, yet the loop expects to get an undecorated option and parse it as the disk dev instead of trying to parse optarg. So, create a new short opt array that is used for manage and grow that doesn't list a as having an argument.
* Improve error message for adding bitmap to a level that cannot support it.Neil Brown2007-05-211-0/+10
| | | | Also give error on --build if no devices given.
* Add --auto-detect for in-kernel autodetect.Neil Brown2007-05-211-0/+7
| | | | This is equivalent to raidautorun that some distros provide.
* Add --export option to --detail to use key=value pairs.Kay Sievers2007-05-081-2/+10
| | | | | | | | udev likes to get information about a device as key=value pairs so it can create disk/by-id links etc. So add --export flag which causes the output of --detail to easily parsable. From: Kay Sievers <kay.sievers@novell.com>
* Send help text to stdout rather than stderr.Neil Brown2007-05-081-9/+17
| | | | This helps with piping to a pager for example.
* Add new mode: --incrementalNeil Brown2006-12-211-0/+39
| | | | | --incremental allows arrays to be assembled one device at a time. This is expected to be used with udev.
* Support --uuid= with --create to choose your own UUID.Neil Brown2006-12-141-0/+2

* Support --examine --brief --verbose properlyNeil Brown2006-10-231-0/+2
| | | | | Similar to -Esv, this combination should print out the 'devices=' line in the otherwise --breif output.
* Improve error message when wrong --update option is given.Neil Brown2006-10-231-1/+7
|
* Don't trigger and error on -As if all arrays are already started.Luca Berra2006-10-161-1/+1
| | | | | | | From: Luca Berra <bluca@comedia.it> Put another way, if we find any active arrays, then assume things are going as planned.
* Allow symlink creation to be disabled from command line or mdadm.confNeil Brown2006-08-111-0/+20
|
* Fix starting of degraded arrays.Neil Brown2006-08-071-5/+3
| | | | | Recent change broke assembling of degraded arrays, making it require --run. This fixes that.
* More consistent honoring of --configfileNeil Brown2006-06-261-15/+16
| | | | | Never use /etc/mdadm.conf if --config file is given (previously some code used one, some used the other).
* Get --stop to honour --quietNeil Brown2006-06-021-4/+4
| | | | | | | And as a side effect, if --quiet isn't given, stopped devices are reported. Signed-off-by: Neil Brown <neilb@suse.de>

* New flag --no-degradedNeil Brown2006-05-191-0/+4
| | | | | | | | | Use to avoid starting arrays if there are fewer devices available than last time the array was started. This is only needed with --scan, as with --scan, that behaviour is the default. Signed-off-by: Neil Brown <neilb@suse.de>
* Arrange the 'auto' setting in mdadm.conf can choose default type.Neil Brown2006-05-161-10/+12
| | | | | | | | | | | | So when you say auto=md or auto=part in mdadm.conf, it give a preference for type of array, but standard name will override. But --auto=md is more insistant. FIXME I'm not at all happy about handling of names that already exist. I don't think that should be removed if the device is active. Signed-off-by: Neil Brown <neilb@suse.de>

* Limit size of bitmap to 2million chunks.Neil Brown2006-05-151-1/+0

* Allow resize to backup to a file.Neil Brown2006-03-271-7/+37
| | | | | | | | | | To support resizing an array without a spare, mdadm now understands --backup-file= which should point to a file for storing a backup of critical data.
