We have 135 TB capacity with about 75 TB in use on zfs based storage.
zfs use started about 2 years ago, and has grown from there. This spans
9 SAN appliances, with 5 "head nodes", and 2 more recent servers running
zfs on JBOD with vdevs made up of raidz2.
So far, the experience has been very positive. Never lost a bit of
data. We scrub weekly, and I've started sleeping better at night. I
have also read the horror stories, but we aren't seeing them here.
We did have some performance issues, especially involving the SAN
storage on more heavily used systems, but enabling the cache on the SAN
devices without pushing fsync through to disk basically fixed that.
Your zfs layout can profoundly effect performance, which is a down
side. It's best to test your setup under an approximate realistic work
load to balance capacity with performance before deploying.
BTW, most of our zfs deployment is on Solaris 10{u4,u5}, but two large
servers are on OpenSolaris svn86. The OpenSolaris servers seem to be
considerably faster, and more feature rich, without any reliability
issues, so far.
