Recently, I purchased an external USB hard drive for backups at home. Specificly, I purchased a Western Digital 120GB USB 2.0 drive. I hooked it up to my Ultra 60. I was not able to see the drive in format and even with vold turned off, I could not label the drive. However, with "format -e", I could atleast see the drive:
# format -e

So, I decided to just create a ZFS pool called "usbstorage":
# zpool create usbstorage c5t0d0s2
# zpool list usbstorage
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
usbstorage 111G 24K 111G 0% ONLINE -
So that worked and I was able to create the file systems I wanted:
# zfs create usbstorage/backups
# zfs set mountpoint=/export/backups usbstorage/backups
# zfs set sharenfs=on rw usbstorage/backups
# share
- /export/backups rw ""
# df -h /export/backups
Filesystem size used avail capacity Mounted on
usbstorage/backups 109G 24K 109G 0% /export/backups
Pretty easy eh? I've already started to use this drive to backup my data. So far, the performance has been excellent. The next thing is to mount this share onto my iMac and backup my data:)
