Speeding ahead with ZFS and VirtualBox | FreedomPenguin
I have created a lot of VMs with VirtualBox and I organize their snapshotting with ZFS.

Replacing a loud fan in my home ZFS NAS
The blue-LED fan I have in my ZFS on Linux NAS is a bit louder than the other fans that I’ve been hoping for. I am going to replace it with a 600rpm fan. You will notice that I have drilled extra ventilation into the top case panel. Notice the clear-plastic fan. It…

Raw ZVOL access in ZFS on Linux not an option for VirtualBox?
I have gotten about as far as I can go…I can boot a Fedora netinstall cd, and I can attempt to fdisk /dev/sda, but this device will not open in fdisk. This might be consistent with no “rdsk” device in the dev tree. Funny though, I can fdisk /dev/zd0, and it lists partitions. Could this…

Converting Virtualbox disk to ZFS volumes
I am trying to create zvol backed virtualbox guests using ZFS on Linux. Hopefully this is not too ambitious. Find size of original .VDI disk image: vboxmanage showhdinfo Fedora19.vdi Pass that file size into zfs create: zfs create -V40960M tank/VMs/Fedora19 Convert .vdi file to raw, best if you can do this from one hd to…

Replacing a Four Drives at Once
I would not have considered this tactic possible, but then I’ve often come from small raid setups or hardware raid setups that are unlikely to want to replace multiple disks at a time. Replacing four at a time!

Two drives fail at once? Oh yeah…
Just as I thot I was all cool for having a sixteen drive NAS, today’s opening of it and trying a new network card (did not fit) left me with bad news on the next powerup. > dmesg | grep ata | grep error: [ 23.223221] ata13.00: error: { ABRT } [ 23.234448] ata13.00: error:…

ZFS on Linux machine
Here is my ZFS on Linux story, and some of you might have seen these pictures when I started this project last year: I recycled an old Athlon system from work and placed an 35 Watt AMD A2 processor with 8GB 1600 ram on an Asus mobo in it. I name my home systems after…

Resilvering: Just what I want to see
I love replacing failed hard drives. Mostly, because I hate having hard drive failures. root@cholla ~ $ zpool attach -f tank ata-ST2000DM001-9YN164_W1E16BJB ata-ST2000DM001-1E6164_W1E5W99Y root@cholla ~ $ zpool status -v pool: tank state: ONLINE status: One or more devices is currently being resilvered. The pool will continue to function, possibly in a degraded state. action: Wait…

Disk Performance Analysis on Linux
Really Into the Guts of LinuxIt is possible to find out how hard your disks are running. Some you don’t want to run as hard as others. For instance, if you wanted to save on write cycles for your SSD you could move small frequent writes into a ram filesystem, and that seems to be…
