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.

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. After setting up a supposedly robust mirrored ZFS root boot pool here using two SSD drives, I decided to give […]
Home Fileserver: Mirrored SSD ZFS root boot
When I started using this ZFS NAS for additional tasks, I realised that my boot environment was becoming more important, and was a weak point in this system.

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.

Home Fileserver: Active Directory Integration
Matt Harrison wrote to me recently, to notify me about a guide he’d written showing how to integrate a ZFS-based OpenSolaris fileserver with Microsoft Active Directory. 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 […]
