Until today I had never encountered even one read, write or checksum error on my ZFS NAS. Today I saw one checksum error coming from the mirrored SSD root boot pool which I have just installed. Unless you’re using a file system like ZFS (or NetApp / Veritas…$$$), then you’ll almost certainly never even know […]

Home Fileserver: ZFS boot pool recovery
If you should be unlucky enough to be unable to boot your OpenSolaris NAS one day, then these notes taken from a real restoration test might help you get back up and running again quickly.

Home Fileserver: OpenSolaris 2009.06
After running SXCE for the last year, due to a failed hardware upgrade, it was time to install OpenSolaris 2009.06.

His guide covers all the necessary areas like: configuring Kerberos, synchronizing time/dates, enabling the CIFS server, joining the domain, user and group mapping, ZFS datasets, setting ACLs and auto-sharing […]
Home Fileserver: RAIDZ expansion
Recently I decided to expand the storage capacity of my ZFS home fileserver’s ZFS storage pool, which was configured to use a single RAIDZ vdev comprising of three 750 GB drives. I wanted to expand the RAIDZ vdev by adding one extra 750 GB drive. As you may or may not be aware, it is […]
Linux to get ZFS?
An intriguing post appeared yesterday on the blog of Jeff Bonwick, where it simply shows photos of an informal meeting between Jeff and Linus Torvalds — could it be that Linux will get ZFS soon, due to changes in licensing, or could Linus be joining the ZFS team with Sun, or something else?

With the summer coming on, the ambient room temperature is increasing, and so here’s a handy script to help you monitor your drive temperatures to help prevent heat-related data loss.
Home Fileserver: Backups from ZFS snapshots
Backups are critical to keeping your data protected, so let’s discover how to use ZFS snapshots to perform full and incremental backups.
Home Fileserver: Trunking
I had two Gigabit ethernet ports sitting on this motherboard and I was only using one. So I decided to take the path less travelled, as you never know where it can lead…
