Just checking to see if people are having success with storage daemon
running on FreeBSD 9.0 with ZFS and compression enabled? I ask because I'm
having issues with the backups completing without any errors reported, but
then an immediate restore attempt fails due to block checksum mismatches,
or trying something like 'bls -j -v -V Full-0079 FileStorage1' will fail
and exit with a block checksum mismatch.
The pool is a raidz1 made up of 5 1.5TB drives. I can run a scrub, get a
clean result, run a backup, then have a restore from that backup fail (only
for larger backups, small ones seem fine). A scrub run after that will
also report errors, usually 1 or 2 out of roughly 600GB of data, and it
will show them as repaired. I'm just trying to determine if I'm being
bitten by the SATA controller, it's an ' <ATI IXP700 AHCI SATA controller>'
and I have to set the storage type to IDE instead of AHCI and set
'hint.ahci.0.msi=0' in loader.conf or the system can't even see the drives.
Or maybe what I'm trying here is a bad idea? I'd just like the
compression without the overhead and slowdown on the clients that comes
from enabling compression in the fileset. I'm a FreeBSD neophyte, is the
SATA/AHCI stuff just not good yet or would much better results be likely
with a newer board/controller?
Thanks for any info,
Mark
