hi friends,
I am having issues with adding a spare device to a failed array.
I have created RAID 1 with 3 partitions using mdadm command. Later I added a spare with
Code:
mdadm --add /dev/md0 /dev/sdb6
This works fine and when I check this with mdadm --detail command it just sits there as a spare device.
And now, if I set one of the active raid device in the array as faulty, the spare device becomes active and the failed device becomes faulty spare. This looks perfect, but once i reboot the machine and type mdadm --detail /dev/md0, both the failed device as well as the spare device are not seen in the array..
Number Major Minor RaidDevice State
0 3 11 0 active sync /dev/hda11
1 3 12 1 active sync /dev/hda12
2 3 13 2 active sync /dev/hda13
3 3 14 - spare /dev/hda14
after the mdadm --fail /dev/hda13
Code:
Number Major Minor RaidDevice State
0 3 11 0 active sync /dev/hda11
1 3 12 1 active sync /dev/hda12
2 3 14 2 active sync /dev/hda14
3 3 13 - faulty spare /dev/hda13
after rebooting..
both the faulty spare (/dev/hda13) and the newly active raid device (/dev/hda14) are removed from the array... and only /dev/hda11 and /dev/hda12 are active.
I touched a file named /etc/mdadm.conf, but nothing is configured there nor any output from that file..

It is a conf file, not a log, so you won't get output. This is probably why you are having your issues. I have given the command on how to create this file.
hi mark,
thanks. I will do as u guided and let u know the results.bye.

mark, I have tried as you mentioned, but i am not successful. The same things happen after I set one of the active device as faulty, (both the faulty device as well as the spare device gets removed...).
