next in thread | raw e-mail | index | archive | help
I'm running 8.0-RELEASE-p2 (amd64) on a larger number of Supermicro
SBI-7425C-T3 blades. Each of the blades has 2 x 500GB disks striped
into a single volume via the on-board ICH9 RAID controller.
However, after running fine for a while (days), the blades crash
eventually with file system problems such as the one below.
Initially I thought that must be a bad disk, but by now 5 different
blades have shown similar problems so I'm suspecting some OS issue.
Has anybody seen something similar before? Could this be an
incompatibility with the RAID controller (I haven't found much
recent on Google but there are a number of older threads indicating
that it might not be well supported. Not sure though whether those
still apply).
Any other thoughts?
Thanks,
Robin
