I am running SME 7.4 - all patches up to date.
I received this email:
A DegradedArray event has been detected on md device /dev/md2.
I then checked the "Manage disk redundancy" and got the following:
Current RAID Status:
Personalities : [raid1]
md2 : active raid1 hda2[0]
390604288 blocks [2/1] [U_]
md1 : active raid1 hda1[0] hdb1[1]
104320 blocks [2/2] [UU]
unused devices: <none>
Only some of the RAID devices are unclean.
Manual intervention may be required.
I went to this link http://wiki.contribs.org/Category:Howto (http://wiki.contribs.org/Category:Howto) and had a read on RAID and I found this section on failed RAID's
Make a note of the raid partition that has failed, shown by [_U]
In this case it is md2, the device being /dev/md2.
Mine does not show [_U] it shows [U_]
Do I still run;
# mdadm --add /dev/md2 /dev/hda2
Any advice would be appreciated.
-
mdadm --add /dev/md2 /dev/hdb2

Thanks Franco, it is running now.
-
Franco,
It has now finished and all appears OK, thank you for your advice.
-
My pleasure,
cat /proc/mdstat
should show you all good.
Thanks,
-
Franco,
Yes it showed "all good"

Check your Harddisk settings it should not be hda2 as you are using sdb2.

-
yours should be
mdadm --add /dev/md2 /dev/sda2
-
yours should be mdadm --add /dev/md2 /dev/sda2
Only after identifying why the first hard drive was thrown out of the RAID array. If the drive is or might be faulty, it should be replaced.

thanks,
rebuilding in progress now.
