Hello all...
I'm looking for a suggestion or two... I have a server running with 2
Western Digital WD4000YR drives running a RAID1 mirror... the other day, I
was lucky enough to have one of the drives fail. Being as they are new(er)
drives, they are still under warrenty, and I'm looking to do an advanced
replacement RMA to swap the drive and allow it to rebuild. The problem is...
I don't have the serial numbers of the hard drives. No big deal... except,
they are SATA drives, and I'm running 2.6.14.6.... honestly, with the main
drive of the mirror failed, I'm afraid to upgrade. I'm also afraid to
upgrade, because I'm still using mdadm v2.2 with v1.00.02 superblocks. I had
a recent raid disaster here at home (see another thread, long story short -
every reboot, the raid 5 rebuilds... during one of those rebuilds, a disk
really failed. bye bye data) - during all my attempts to recover from it, I
upgraded to a newer mdadm and kernel, and it refused to recognize my raid
superblocks! I had to revert to mdadm 2.2, and the old kernel to see the
superblocks again (still... 26 of 28, did me little good... and forcing 27
of 28 with 1 missing using the partially rebuilt disk, I think did even less
good).
What options do I have to retreive the serial number without driving out to
the datacenter and looking at the drive? Do I need to be afraid of upgrading
my kernel and mdadm and having my superblock go poof?
