Hmm... Maybe I got lucky/had an empty filesystem/hallucinated last time,
but in any event when I try pulling the power on a drive now I get an
error about a block not being found... Less than reassuring:
drive 1:
/dev/gvinum/big: CAN'T CHECK FILE SYSTEM
/dev/gvinum/big: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
drive 2:
/dev/gvinum/big: CANNOT READ BLK: 1401158656
/dev/gvinum/big: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
drive 3:
/dev/gvinum/big: CANNOT READ BLK: 1401158656
/dev/gvinum/big: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
drive 4:
Cannot find file system superblock
/dev/gvinum/big: CANNOT READ BLK: 1401158656
/dev/gvinum/big: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
/dev/gvinum/big: CANNOT WRITE BLK: 12000
/dev/gvinum/big: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
---
THE FOLLOWING FILE SYSTEM HAD AN UNEXPECTED INCONSISTENCY:
ufs: /dev/gvinum/big (/home)
Automatic file system check failed; help!
Pulling power on the RAID0/RAID1 arrays I have does what I expect it to
do... Anyone have any idea what's going on here?
Cheers,
