Hello,
I have reviewed the Linux Raid Wiki regarding rebuilding and it
recommended writing a note to the list.
I am running an mdadm raid on CENTOS 6.5 with 6 disks in a Raid 6 off of
my motherboard's SATA controller.
I added a 7th disk as a spare.
When I rebooted the raid after adding the spare, it would not mount and
the OS would only boot into recovery mode. I changed my fsck file to
exclude the raid and can now boot into the GUI.
I have tried to reassemble the array using --assemble and I get the the
following message:
mdadm: we match both /dev/md/BigBlue:0 and /dev/md0 - cannot decide
which to use.
I am including the output of the mdadm --examine below.
I am considering using --force to assemble the array, though I suspect
that this is something simple that I am overlooking -- I am quite new to
linux.
Any input would be appreciated.
- Justin
