Hi Paul,

I have been testing ZoL for a while now (somewhere around a year?) on two separate machines:


1) dual Socket 771 Xeon , 8GB ECC RAM, 12 Seagate 1TB ES.2 HD (2x6 disk raidz2), ubuntu oneiric, with the zfs-native/stable PPA 2) Intel Xeon CPU E31120, 8GB ECC RAM, 4 x 400GB WD RE2 ( 1 4 disk raidz1), ubuntu oneiric, zfs-native/daily PPA

I would consider neither the daily nor the stable good enough for production use.

I frequently get pools with all or nearly all of the disks marked as removed (a simple zfs export; zfs import -f fixes this). I also got kernel panics under heavy random IO (backuppc) on #1. I recently switched to openindiana on that machine, which is stable for the same workload.

On machine #2 (my office workstation) I get routine crashes and slow performance (the raidz holds my home directory)

That being said, I haven't lost any data yet, and bugs that have been affecting me are quickly fixed, so I think that at some point it will be stable, just not right now.

This may fall into the realm of a religious war (I hope not!), but recently several people on this list have said/implied that ZFS was only acceptable for production use on FreeBSD (or Solaris, of course) rather than Linux with ZoL.

I'm working on a project at work involving a large(-ish) amount of data, about 5TB, working its way up to 12-15TB eventually, spread among a dozen or so nodes. There may or may not be a clustered filesystem involved (probably gluster if we use anything). I've been looking at ZoL as the primary filesystem for this data. We're a Linux shop, so I'd rather not switch to FreeBSD, or any of the Solaris-derived distros--although I have no problem with them, I just don't want to introduce another OS into the mix if I can avoid it.

So, the actual questions are:

Is ZoL really not ready for production use?

If not, what is holding it back? Features? Performance? Stability?

If not, then what kind of timeframe are we looking at to get past whatever is holding it back?
