* Assemble: don't auto-assemble if any arrays are listed in mdadm.confsles11NeilBrown2008-11-201-2/+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

* 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>

* ddf: store homehost information to allow smooth assembly.NeilBrown2008-11-041-0/+2
| | | | | | | When we create our own ddf array, store the homehost in the vendor information so it can be so to ensure 'LOCAL' name choices. Signed-off-by: NeilBrown <neilb@suse.de>
* Create: make sure chosen_name is used for array name generation in CreateNeilBrown2008-11-041-0/+1
| | | | | | | As with Assemble, one create_mddev has chosen a name, we should always use that rather than the passed 'mddev'. Signed-off-by: NeilBrown <neilb@suse.de>
* Create: Don't optimise resync as recovery when creating raid5 in a container.NeilBrown2008-11-041-1/+2
| | | | | | | | As spares are treated quite differently in containers, we cannot fake-up a spare to optimise initialisation for a raid5 in a container, so disable that code for ->external arrays. Signed-off-by: NeilBrown <neilb@suse.de>
* mdopen: use small sequence number for uniquifying array names.NeilBrown2008-11-044-10/+44
| | | | | | | | | Rather than appending the md minor number, we now append a small sequence number to make sure name in /dev/md/ that aren't LOCAL are unique. As the map file is locked while we do this, we are sure of no losing any races. Signed-off-by: NeilBrown <neilb@suse.de>
* Assemble: revise detection of 'autoassemble' mode.NeilBrown2008-11-041-1/+3
| | | | | | | | We probably should pass a flag down saying 'this is auto-assembly', but for now, if there is no identity information set, it must be auto-assemble. Signed-off-by: NeilBrown <neilb@suse.de>
* DDF: report member arrays in examine_brief.NeilBrown2008-11-042-11/+27
| | | | | | Thus an auto-generated config file will list all the arrays. Signed-off-by: NeilBrown <neilb@suse.de>
* DDF: fix irregularities with retrieval of 'name' from metadata.NeilBrown2008-11-041-3/+12
| | | | | | It is only 16 bytes, not 32. And is space padded, not nul terminated. Signed-off-by: NeilBrown <neilb@suse.de>
* Assemble: allow members of containers to be assembled and auto-assembled.NeilBrown2008-11-045-1/+113
| | | | | | | | | | 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>
* Assemble: simplify test for reporting mismatches.NeilBrown2008-11-041-11/+13
| | | | | | | Rather than open-coding a test of 'verbose' and 'inargv' in multiple places, do it one and set a variable. Signed-off-by: NeilBrown <neilb@suse.de>
* Assemble: block attempts to reassemble container membersDan Williams2008-11-041-0/+25
| | | | | | | | | | | | | Attempting to open(O_EXCL) each candidate device usually filters out all busy raid components. However, containers do not behave like components and will return container_content that may describe active member arrays. This patch just adds a function that will be used to check if a container member is busy. It will be used shortly.

* Assemble: factor out assemble_container_contentDan Williams2008-11-043-56/+76
