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 […]
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 […]
The UK seems to be embarking on a big nuclear power plant building exercise, to replace existing plants about to be decommissioned, to help reduce reliance on oil and gas, to reduce the carbon footprint and to increase availability of power for increasingly power-hungry consumers. These new plants will most likely be the new EPR […]
I knew it was only a matter of time before this happened, due to seeing high traffic in the web server logs and lots of links appearing, but today my website was Slashdotted. If you are a webmaster, this is either your best day ever, or your worst nightmare, depending on how robust your web […]
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.
Backups are critical to keeping your data protected, so let’s discover how to use ZFS snapshots to perform full and incremental backups.
The next thing you will want to master when running your own ZFS home fileserver is how to perform snapshots of your file systems, as this is a crucial part of helping to protect your data.
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…
Considering that a fileserver at home will spend a lot (most) of its life idle, it makes sense to look at its power usage and see what steps can be taken to reduce its operational costs — i.e. power consumption.
