Hi all
a colleague of mine created a raid 1 on a fairly recent machine
Kernel 3.5.0-sabayon
mdadm - v3.2.3 - 23rd December 2011
During operation sda seemed to have been disconnected by the
system/motherboard/whatever but this was not detected before a reboot
was done, after the reboot, sda re-appeared but of course with a much
older version of the mirror:
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5]
[raid4] [multipath] [faulty]
md126 : active raid1 sdb1[1]
4194240 blocks [2/1] [_U]
md127 : active raid1 sdb3[1]
235808704 blocks [2/1] [_U]
md0 : active raid1 sda1[0]
4194240 blocks [2/1] [U_]
md1 : active raid0 sda2[0] sdb2[1]
8387584 blocks 512k chunks
md2 : active raid1 sda3[0]
235808704 blocks [2/1] [U_]
unused devices: <none>
As no vital information were on these disks, my question for the list is
just if this is an expected/wanted behavior after such an event and what
one could do to prevent this (besides monitoring via mdadm).
Cheers
Carsten
