#wishihadbackups

I had plans for tonight.

I was going to

Critical Alerttweak the rc script in the MediaBrowser FreeBSD port,

update my GitHub pull request to plexhometheater to upstream my FreeBSD patches, and

work on getting OpenWrt installed on my new TP-Link Archer D9 wireless modem router.

But then this happened:

Hmmm... that doesn't look good! Let's see what we've got here...

freenas% zpool status pool: zstore state: DEGRADED status: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Attach the missing device and online it using 'zpool online'. see: http://illumos.org/msg/ZFS-8000-2Q scan: scrub repaired 0 in 1h53m with 0 errors on Tue Nov 11 17:10:55 2014 config:

Since I am running raidz2 with 4 disks, having 2 failures means I am on my last legs here; if either of the remaining drives fails I lose ALL my data! Damn I wish I had that backup I've been talking about...

To cut a long story short, I shutdown, checked all the wiring connections in the FreeNAS mini, and after rebooting I had 4 drives showing again. I have read that resilvering can stress the remaining good disks, so I was nervous. But I charged forth and used the FreeNAS GUI replace button, and the first drive has just now finished resilvering (3 hours later for 1.7Tb of data).

The heat is off... at least I have some redundancy back. I'm off now to get that 4th disk back.
