Subject: Raid failing, which command to remove the bad drive?
Date: Fri, 26 Aug 2011 13:13:01 -0700 [thread overview]
Message-ID: <4E57FE4D.5080503@vorgon.com> (raw)
I have 4 drives set up as 2 pairs. The first part has 3 partitions on
it and it seems 1 of those drives is failing (going to have to figure
out which drive it is too so I don't pull the wrong one out of the case)
It's been awhile since I had to replace a drive in the array and my
notes are a bit confusing. I'm not sure which I need to use to remove
the drive:
sudo mdadm --manage /dev/md0 --fail /dev/sdb
sudo mdadm --manage /dev/md0 --remove /dev/sdb
sudo mdadm --manage /dev/md1 --fail /dev/sdb
sudo mdadm --manage /dev/md1 --remove /dev/sdb
sudo mdadm --manage /dev/md2 --fail /dev/sdb
sudo mdadm --manage /dev/md2 --remove /dev/sdb
or
sudo mdadm /dev/md0 --fail /dev/sdb1 --remove /dev/sdb1
sudo mdadm /dev/md1 --fail /dev/sdb2 --remove /dev/sdb2
sudo mdadm /dev/md2 --fail /dev/sdb3 --remove /dev/sdb3
I'm not sure if I fail the drive partition or whole drive for each.

A Fail event had been detected on md device /dev/md0.
It could be related to component device /dev/sdb1.
Faithfully yours, etc.
P.S. The /proc/mdstat file currently contains the following:
