* Pass the device name to arrays_in_domain along with the domainDoug Ledford2010-04-152-3/+12
| | | | | | | | | | This allows us to pull the path information for our current device and filter the list of possible matching domains based upon that path information. Since we only support identical partition tables, if an array is comprised of -part1 partitions already, then we know that our new device will only match on -part1 as well.

* The assumption is that if tfd >= 0, then we have a valid major/minor pairDoug Ledford2010-04-131-6/+6
| | | | | | | | | | | | | | | in stb.st_rdev to use in ioctl calls. Therefore, even if we use the sysfs block/dev entry to get our major/minor pair, we should really be using tfd and not sysfd as it changes assumptions made later on. Note: I actually don't like this. I would prefer that in the case of a kernel internal name that we skipped tfd altogether and went strait to sysfs operation exclusively. But that's just my preference. I'm concerned that sometime in the future we'll make the mistake of assuming that tfd >= 0 means dv->devname is a fully qualified path name and not a kernel internal name. We don't now, but I could easily see it happening. Signed-off-by: Doug Ledford <dledford@redhat.com>

* Fix all the confusion over directories once and for all. We now haveDoug Ledford2010-04-136-65/+46
| | | | | | | | | | | | 3 directory definitions: mdmon directory for its pid and sock files, mdmonitor directory which is for the mdadm monitor mode pid file and can only be passed in via command line, and the directory for the mdadm map file. Only the mdadm map file still hunts multiple locations, and the number of locations has been reduced to /var/run and the compile time specified location. I could see lowering that to just 1 location, but I didn't do that with this patch. Signed-off-by: Doug Ledford <dledford@redhat.com>
* Update udev rules for hotplug support.NeilBrown2010-04-091-6/+6
| | | | | | | | | - split the rules for handling components of array to be clearly separate from rules for handling the arrays themselves. - add call to "-If" when removing a device - uncomment the --incremental call when adding a device. Signed-off-by: NeilBrown <neilb@suse.de>
* Add -fail support to --incrementalNeilBrown2010-04-096-9/+88
| | | | | | | | | | | | | This can be used for hot-unplug. When a device has been remove, udev can call mdadm --incremental --fail sda and mdadm will find the array holding sda and remove sda from the array. Based on code from Doug Ledford <dledford@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>
* Support fail/remove using kernel nameNeilBrown2010-04-091-20/+81
| | | | | | | | | | Allow kernel names like "sda" and "hdb1" to be used to fail/remove devices from an array. This is useful as after a device has been removed it can be difficult to get the major/minor number. Signed-off-by: NeilBrown <neilb@suse.de>
* Add mdstat_by_componentNeilBrown2010-04-092-6/+68
| | | | | | | | | | | | | This allows finding the array which contains a given component. Components are named using the kernel-internal string name such as "sda1" or "hdb". Don't return member arrays, only the contain that contains them. Also tidy up the parsing of 'inactive' arrays in /proc/mdstat. If we see 'inactive' we need to set 'in_devs' immediately as there is no level coming. Signed-off-by: NeilBrown <neilb@suse.de>
