Hi,
My server seems to have had a bad night, and so I'm not having the
best morning. Overnight three drives failed in my RAID6 array. Worse,
that's on top of one failure I already knew about, so 4 drives in
total.
I put this down to problems with the controller - I had been using
3ware 9650 controllers (in JBOD mode). This morning I've loaded the
drives into another server connected to the on board Intel AHCI SATA
ports and an extra Sil3132 controller.
My first naive attempt was to try re-assembling the array from the
eight most up-to-date member devices:
hermes:~# mdadm -A /dev/md5 /dev/sd[cefghijk]1
mdadm: failed to RUN_ARRAY /dev/md5: Input/output error
I assume that's not an I/O error with the underlying device? I can't
see anything indicating that dmesg/syslog.
Output from "mdadm -E /dev/sd[cdefghijkl]1" included below.
Any advice would be much appreciated.
(and now, back to scouring the mail archives for clues).
Cheers,
Kevin.
