+1 on both. Mostly SmartOS, some FreeNAS (which is FreeBSD underneath). -r Ryan Brooks <ryan@hack.net> writes:

Are you running ZFS and RAIDZ on Linux or BSD?

I'm just going to chime in here since I recently had to deal with bit-rot affecting a 6TB linux raid5 setup using mdadm (6x 1TB disks)
We couldn't rebuild because of 5 URE sectors on one of the other disks in the array after a power / ups issue rebooted our storage box.
We are now using ZFS RAIDZ and the question I ask myself is, why wasn't I using ZFS years ago?
+1 for ZFS and RAIDZ

Raid10 is the only valid raid format these days. With the disks as big as they get these days it's possible for silent corruption.
How do you detect it? A man with two watches is never sure what time it is.
Unless you have a filesystem that detects and corrects silent corruption, you're still hosed, you just don't know it yet. RAID10 between the disks in and of itself doesn't help.
And with 4TB+ disks that is a real thing. Raid 6 is ok, if you accept rebuilds that take a week, literally. Although the rebuild rate on our 11 disk raid 6 SSD array (2TB) is less then a day.
I did a rebuild on a RAIDZ2 vdev recently (made out of 4tb WD reds). It took nowhere near a day let alone a week. Theoretically takes 8-11 hours if the vdev is completely full, proportionately less if it's not, and I was at about 2/3 in use.
