* config: add 'homehost' option to 'AUTO' line.NeilBrown2010-03-031-2/+16
| | | | | | This allows basing auto-assembly decisions on whether the array is recorded as belonging to this host or not. Signed-off-by: NeilBrown <neilb@suse.de>

* mapfile - when rebuilding, choose an appropriate name is none is found.NeilBrown2009-05-111-0/+70
| | | | | | | | When rebuilding the mapfile (mdadm -Ir), if not appropriate name is found in /dev/md/, try to find an appropriate name, either by looking in mdadm.conf or by using the name in the metadata. Signed-off-by: NeilBrown <neilb@suse.de>
* config: enhance name matching in conf_get_ident.NeilBrown2009-05-111-1/+1
| | | | | | | | | | Use when searching mdadm.conf for a device, use more flexible matching that e.g. ignores leading /dev/md/ or /dev/ As mdadm now accepts both "/dev/md/foo" and "foo" is many places as equivalent, they should compare as the same. Signed-off-by: NeilBrown <neilb@suse.de>
* Allow homehost to be largely ignored when assembling arrays.NeilBrown2009-05-111-2/+62
| | | | | | | | | | | | | | | | | | | | | | | | If mdadm.conf contains HOMEHOST <ignore> or commandline contains --homehost=<ignore> then the check that array metadata mentions the given homehost is replace by a check that the name recorded in the metadata is not already used by some other array mentioned in mdadm.conf. This allows more arrays to use their native name rather than having an _NN suffix added. This should only be used during boot time if all arrays required for normal boot are listed in mdadm.conf. If auto-assembly is used to find all array during boot, then the HOMEHOST feature should be used to ensure there is no room for confusion in choosing array names, and so it should not be set to <ignore>.

* config: allow Array line to contain array name without /dev/md/ prefix.NeilBrown2009-05-111-5/+40
| | | | | | | | | | | | | | | For consistency with --create and --assemble, allow the array name given in mdadm.conf to exclude the "/dev/md/" prefix. So e.g. ARRAY home uuid=whatever is treated like ARRAY /dev/md/home uuid=whatever Also exclude names which create_mddev will reject. Signed-off-by: NeilBrown <neilb@suse.de>
* Fix tests on ->container and ->memberNeilBrown2009-05-111-1/+1
| | | | | | | | For container= and member= to be effective in an mdadm.conf line they must both be present. So when checking for their absence we need container != NULL || member != NULL. Signed-off-by: NeilBrown <neilb@suse.de>
* conf/assemble: new config line "auto".NeilBrown2009-05-111-2/+63
| | | | | | | | | | | | | | | | | | | The line 'auto' in mdadm.conf can be used to disable assembly of specific metadata types, or of all arrays. This does not affect assembly of arrays listed in mdadm.conf or on command line. auto -all will disable all auto-assembly. auto -ddf will cause mdadm to ignore ddf arrays that are not explicitly mentioned, and auto assemble anything else it finds. Signed-off-by: NeilBrown <neilb@suse.de>
* config: support "ARRAY <ignore> ..." lines in mdadm.confNeilBrown2009-05-111-1/+1
| | | | | | | | | | | | | | Sometimes we want to ensure particular arrays are never assembled automatically. This might include an array made of devices that are shared between hosts. To support this, allow ARRAY lines in mdadm.conf to use the word "ignore" rather than a device name. Arrays which match such lines are never automatically assembled (though they can still be assembled by explicitly giving identification information on the mdadm command line.

* | Assemble: allow members of containers to be assembled and auto-assembled.NeilBrown2008-11-041-0/+3
| | | | | | | | | | | | | | | | | | | | Try to treat members of containers much like other arrays for assembly. We still look through the list of devices for a match (it will be the container), then find the relevant 'info' and try to assemble the array. Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | | | | | | | | | | | mdadm.conf When mdadm.conf is automatically generated, we might not know a suitable /dev/name. But we do know the uuid of the container. So allow that as an option. Signed-off-by: NeilBrown <neilb@suse.de>
* | config: Don't require an array to have a device name.NeilBrown2008-11-041-5/+4
| | | | | | | | | | | | | | | | | | | | i.e. in mdadm.conf you can have a line like ARRAY uuid=whatever and it will use auto-name-generation to give a name to the array at assemble-time. The is different from blind auto-assembly in that the array will be treated as 'local'.

* | Add support for assembling specific subarrays.NeilBrown2008-09-181-0/+6
|/ | | | | This normally isn't needed as --incremental does all the work. But it is needed to recognise member= and container= in mdadm.conf
* Fix for segfault when reading /proc/mdstatNeil Brown2008-04-281-0/+13
| | | | | | | | | Some kernel versions don't put a space between 'active' and '(auto-read-only)' in /proc/mdstat. This causes a parsing problem leaving 'level' set to NULL which causes a crash. So synthesise a space there if it is missing, and check for 'level' to be NULL and don't de-ref if it is.

* Add new mode: --incrementalNeil Brown2006-12-211-1/+17
| | | | | --incremental allows arrays to be assembled one device at a time. This is expected to be used with udev.
* Default to --auto=yesNeil Brown2006-12-141-0/+1

* Strdup the bitmap file name found in the config fileNeil Brown2006-11-091-1/+1
| | | | Otherwise we quickly lose it...
* Allow a number after --auto=yesNeil Brown2006-10-131-0/+2
| | | | | | So if the device name is /dev/md/d0, then the number of partitions is as given. This is useful in 'CREATE' in mdadm.conf
