Correction: "ZFS has run VERY stably for us with data integrity issues at all." should read "ZFS has run VERY stably for us with NO data integrity issues at all."

Hi Jeff, We're running a FLX210 which I believe is an Engenio 2884. In our case it also is attached to a T2000. ZFS has run VERY stably for us with data integrity issues at all. We did have a significant latency problem caused by ZFS flushing the write cache on the array after every write, but that can be fixed by configuring your array to ignore cache flushes. The instructions for Engenio products are here: http://blogs.digitar.com/jjww/?itemid=44 We use the config for a production database, so I can't speak to the NFS issues. All I would mention is to watch the RAM consumption by ZFS. Does anyone on the list have a recommendation for ARC sizing with NFS?

I have configured a couple of zpools from Volume groups on the Engenio box - 1x2.5TB and 1x3.75TB. I then created sub zfs systems below that and set quotas and sharenfs'd them so that it appears that these "file systems" are dynamically shrinkable and growable. It looks very good... I can see the correct file system sizes on all types of machines (Linux 32/64bit and of course Solaris boxes) and if I resize the quota it's picked up in NFS right away. But I would be the first in our organization to use this in an enterprise system so I definitely have some concerns that I'm hoping someone here can address. > > 1. How stable is ZFS? The Engenio box is completely configured for RAID5 with hot spares and write cache (8GB) has battery backup so I'm not too concerned from a hardware side. I'm looking for an idea of how stable ZFS itself is in terms of corruptability, uptime and OS stability. > > 2. Recommended config. Above, I have a fairly simple setup. In many of the examples the granularity is home directory level and when you have many many users that could get to be a bit of a nightmare administratively. I am really only looking for high level dynamic size adjustability and am not interested in its built in RAID features. But given that, any real world recommendations? > > 3. Caveats?

Since all data access is via NFS we are concerned that 32 bit systems (Mainly Linux and Windows via Samba) will not be able to access all the data areas of a 2TB+ zpool even if the zfs quota on a particular share is less then that.
