Hi all,
I am running a scrub on a SSD-only zpool on r018. This zpool consists of
16 iSCSI targets, which are served from two other OmniOS boxes -
currently still running r016 over 10GbE connections.
This zpool serves as a NFS share for my Oracle VM cluster and it
delivers reasonable performance. Even while the scrub is running, I can
get approx 1200MB/s throughput when dd'ing a vdisk from the ZFS to
/dev/null.
However, the running scrub is only progressing like this:
root@zfsha02gh79:/root# zpool status ssdTank

These are all Intel S3710s with 800GB and I can't seem to find out why
it's moving so slowly.
Anything I can look at specifically?
Thanks,
Stephan
