Zpool configuration, post Veritas

Zpool configuration, post Veritas

Zpool configuration, post Veritas

I need some advice on handling our new zpool (Solaris 10).

We first received the x4540 thumper which came preconfigured with raidz, which worked fine.  Then, someone in our dept decided we needed Veritas, which ended up not working out (I hate that product anyway).   Now, we're backing out Veritas, flattening the volumes to free up disk space for creation of a zpool, where the data will be re-migrated.

I read a couple of articles on "best practices" out there.  It seems that mirroring is the most recommended solution.   The server has 30+ terabytes of data, but we are quickly eating it up with the media we store, which is mostly video files and their associated data.   These volumes are in turn made available internally via NFS for different purposes.

We've managed to free up these disks for the initial zpool, which I'll then add others to (presuming mirroring):


I read about building your storage using dynamically  striped RAID-Z groups of (Y / X) devices.  Sounds a little complicated to me.

So before I go in and make a config that I can't easily back out of (grin), I thought someone out there might have some advice/tips about the zpool config I build.   

Another side issue is that we've been using rsync to replicate our nightly data (runs hourly or so).   We're going to back this out and start sending ZFS snapshots to our remote thumper (similar system), but I've read that there are problems maintaining metadata like NFS handles and such, which must be in order on the remote system (it's a failover).   Anyone know the currents status of that issue?

Thanks in advance!

RE: Zpool configuration, post Veritas

I haven't had to muck with my Solaris 10 X4500 much, but this is how we have our pools set up:

  pool: diskpool1
 state: ONLINE
 scrub: none requested

        NAME        STATE     READ WRITE CKSUM
        diskpool1   ONLINE       0     0     0

We have 3 or 4 shared spares spread across the various zfs pools.

Hope that helps.
