Today we received a new storage array : a Dell PowerVault MD3600f with two MD1200 expension units. In order to use those new disks, we had a bit of home work todo. Here's how we did it.
But you must be warned : this ain't my best blog post.

HOWTO : Replace a failed disk drive in a FreeBSD ZFS pool
In this blog post, we will repair a broken ZFS pool from a FreeBSD server. The machine is running FreeBSD 9.2, but so long as your FreeBSD machine runs a ZFS enabled FreeBSD, all the commands in this article should work.
A little background on this machine. It's been in production for about four years now. It was originally installed with four 750 GB disk drives as a raidz2 pool. The OS has been upgraded several times and so is the disk drives (because that's what fails of course, hence this post). This is a ZFS-only machine built by following the ZFS only FreeBSD installation wiki with GPT formated disks.

How to remove an FC LUN from a running RedHat 6 server.
This quick howto document shows how to remove a fibre channel LUN under multipathd(8) control from a running RedHat Enterprise Linux 6 machine. Be careful when performing online storage modifications. Make sure you have a valid backup. And of course I can't be held resonsible for any problems if you follow these steps ;)
