That might be close enough. I need to set up a test system and play
around with zfs and btrfs.
Thanks.

The most recent release of OpenSolaris was over 5 years ago. You're

Hey guys, I am running it on freeBSD. (nas4free)
It's my understanding that when a resilver happens in a zpool, only the
data that has actually been written to the disks gets used, not the whole
array like traditional raid5 does, reading even empty blocks. I know I
should be using RAIDZ2 for this

This is the normal type of quota within ZFS. it is applied to a

Disk space by uid (by group is a plus but not critical), like BSD and

may not (certainly not) be called inodes but an upper limit to the

As for conversion between RAID levels; usually dump and restore are
your best bet.
Even if your controller HBA supports a RAID level migration; for a

I keep reading zfs vs btrfs articles an
+1 on both. Mostly SmartOS, some FreeNAS (which is FreeBSD underneath).

Are you running ZFS and RAIDZ on Linux or BSD?

Well, it depends on what you mean by

because it is not production on linux, which i have to use because
freebsd does not have kvm/ganeti. want zfs very very badly. snif.

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

How do you detect it? A man with two watches is never sure what time it is.
