Hi, I'm running a 3Tb RAIDZ2 array and was wondering about the zfs scrub function.
This server runs as my backup server and receives an rsync every night. I was wondering if I _need_ to explicitly run a zfs scrub on my zpool periodically. There's a lot of info on google about running a scrub but not whether it's actually needed or under what circumstances you might run one - so I thought I'd ask the list it's opinions on this. If zfs does a background scrub continually anyways - is there any need to manually run a scrub? I'd imagine a scrub of a 3Tb array would take quite a while (its 7200rpm SATA disks) and if I ran a scrub this would likely overlap with my nightly rsyncs causing yet more I/O. Wouldn't this stress the disks more? If it is necessary - how often are people running a manually scrub? Once a week? month? regards D -- Douglas Walker Systems Administrator Jones Coulter Young Architects 321 Murray St, Perth WA, 6000 _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
