Bug#947806: systemd doesn't like my raid, times out waiting for online partitions to come online, and can't continue boot

[Joshua Hudson]

>> Dec 31 08:27:23 nova dmraid-activate[554]: ERROR: Cannot retrieve RAID
set information for isw_cfbejbfeib_Volume1
> Have you further investigated those error messages?

I have now investigated and it's clearly spurious.

udev tries to run the following commands:

/sbin/dmraid-activate /dev/sda
/sbin/dmraid-activate /dev/sdb
/sbin/dmraid-activate sda
/sbin/dmraid-activate sdb

The first two are correct and succeed. The second two are not correct
and fail. The failure results in log spam.

> Have you tried with mdadm instead?

mdadm doesn't recognize the raid descriptor.

> udevadm info /dev/mapper/isw_cfbejbfeib_Volume14

output of this command for this device and all similar devices attached.
