With ZFS, you set a partition label on the whole-drive partition pool member, then mount the pool with something like ?zpool mount -d /dev/disk/by-partlabel?, which then shows the logical disk names in commands like ?zpool status? rather than opaque ?/dev/sdb3? type things. It is then up to you to assign sensible drive names like ?cage-3-left-4? for the 4th drive down on the left side of the third drive cage. Or, maybe your organization uses asset ta...

Morning all, I have a HP Envy dual boot system (Win8 for serious stuff, i.e. Train Sim and Flight Sim) and Centos 7 for everything else. In the past I've had the occasional problem where an update on the windows side has updated the UEFI boot sequence but using efibootmgr has always fixed it. On Friday I discovered that my HDD was failing so I tried using Clonezilla to move it on to a new

That module should be available.

Speaking of ZFS, got a weird one: we were testing ZFS (ok, it was on Ubuntu, but that shouldn't make a difference, I would think). and I've got a zpool z2. I pulled one drive, to simulate a drive failure, and it rebuilt with the hot spare. Then I pushed the drive I'd pulled back in... and it does not look like I've got a hot spare. zpool status shows config: NAME STATE
