About six months ago I applied the ZFS config I described above to the actual hardware, running FreeBSD 8.1. Current usage is:
Code:
Filesystem Size Used Avail Capacity Mounted on
/dev/ad1s1a 3.9G 266M 3.3G 7% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/ad1s1d 9.7G 12K 8.9G 0% /tmp
/dev/ad1s1e 58G 410M 53G 1% /usr
/dev/ad1s1f 150G 116G 22G 84% /var
tank 689G 22K 689G 0% /tank
tank/Backups 689G 18K 689G 0% /tank/Backups
tank/MyStuff 690G 1.1G 689G 0% /tank/MyStuff
tank/Warehouse 1.6T 909G 689G 57% /tank/Warehouse
My experience with the setup has been very good, with NFS access provided to a variety of machines over my network. The only thing I have found is that the system can be quite slow at times, I think that this is down to it being ZFS overhead etc but I am investigating this. That said, I've had no crashes or errors. I have been keeping monthly rsync'd backups to several large external hard disks just in case.
Next steps are to setup some automated monitoring of the health of the zpool etc and mail the results out to me nightly.
