* Uclibc has deprecated 'random' so use 'rand' instead.Neil Brown2006-05-291-0/+3
| | | | | | | | | | | glibc says of rand Do not use this function in applications intended to be portable when good randomness is needed. Go figure... Signed-off-by: Neil Brown <neilb@suse.de>
* add CFLAGS to mdassemble build and fix a couple of non-returning functionsNeil Brown2006-05-291-4/+2
| | | | | | | | pass CFLAGS to mdassemble build, enabling -Wall -Werror showed some issues also fixed by the patch. From: Luca Berra <bluca@vodka.it> Signed-off-by: Neil Brown <neilb@suse.de>
* Support --auto-update-homehostNeil Brown2006-05-261-0/+1
| | | | | | | | | This can be used to bootstrape homehost tagging. If no arrays are found that are tagged, we look for any array and tag it. Signed-off-by: Neil Brown <neilb@suse.de>
* When assembly arrays using incomplete detail, prefer arrays built for this host.Neil Brown2006-05-231-0/+1
| | | | | | | | i.e. if assembling with --name or --super-minor, then if we find two different arrays with the same apparent identity, and one was built for 'this' host, then prefer that one instead of giving up in disgust. Signed-off-by: Neil Brown <neilb@suse.de>
* Reorganise Assemble code somewhat.Neil Brown2006-05-231-0/+1
| | | | | | | | | | | We make sure all devices can are consistent before doing any --update This saves us from updating some but not all of an array, and then aborting. It also means we can backtrack on out decisions, which we might want to do later. Signed-off-by: Neil Brown <neilb@suse.de>
* Make sure homehost is set correctly when --update=uuidNeil Brown2006-05-231-2/+4

* Include homehost information in --examine as appropriateNeil Brown2006-05-191-2/+2

* Include homehost information in --detail where appropriate.Neil Brown2006-05-191-2/+2
| | | | Signed-off-by: Neil Brown <neilb@suse.de>
* Make homehost information appear in superblock.Neil Brown2006-05-191-2/+2
| | | | | | | | When an array is created, if the homehost is know, the superblock gets it, either in the uuid, (via sha1) or in the name field. Signed-off-by: Neil Brown <neilb@suse.de>
* Allow homehost to be set on command line or in config fileNeil Brown2006-05-191-0/+15

* Arrange the 'auto' setting in mdadm.conf can choose default type.Neil Brown2006-05-161-1/+1
| | | | | | | | | | | | 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>
* When updating uuid, update the bitmap as well - external bitmapsNeil Brown2006-05-161-0/+1

* Allow default creation info to to be stored in mdadm.confNeil Brown2006-05-151-1/+9
| | | | | | Default owner, group, mode and 'auto' flag can be given in a 'CREATE' line. Signed-off-by: Neil Brown <neilb@suse.de>
* Support 'mailfrom' line in mdadm.conf so the From: line in alert emails can ↵Neil Brown2006-05-151-0/+1

* Use O_DIRECT to read bitmap files.Neil Brown2006-05-151-2/+1
| | | | | | | | A pending patch to the kernel causes bitmap file updates to not go through the page cache, so O_DIRECT is needed to ensure that we read current data. Signed-off-by: Neil Brown <neilb@suse.de>
* Support 'bitmap=' in mdadm.conf for auto-assembling arrays with write-intent ↵Neil Brown2006-03-291-0/+1
| | | | | | bitmaps in separate files. Signed-off-by: Neil Brown <neilb@suse.de>
* Kill old superblocks on create.Neil Brown2006-03-281-1/+1
| | | | | | | Make sure old-version superblocks are not around to confuse anything when a new array is created. Signed-off-by: Neil Brown <neilb@suse.de>
* Create missing /dev files where needed.Neil Brown2006-03-281-1/+1
| | | | | | | Whenever we need a device file to open, if one cannot be found in /dev, create a temporary one. Signed-off-by: Neil Brown <neilb@suse.de>
* Allow resize to backup to a file.Neil Brown2006-03-271-3/+4
| | | | | | | | | | 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. This can be given to --grow which will create the file, or --assemble which will restore from the file if needed. Signed-off-by: Neil Brown <neilb@suse.de>
* Remove ident arg from getinfo_super;Neil Brown2006-03-271-1/+2
| | | | | | Add a 'name' field to 'info' to compensate. Signed-off-by: Neil Brown <neilb@suse.de>

* Create version-4 bitmaps if kernel supports it.Neil Brown2005-10-111-2/+3
