Today I had a disk fail in my ZFS pool...


Recommended Posts

It was a complete non event, even the music kept playing. I pulled the bad disk, plugged in a replacement, resilvered the pool and we're back up and running.

 

At no time did music playback stop until I manually stopped it just to let the resilvering go without the need to play music at the same time. IMO this is the best reason to have music stored on a system with fault tolerance and redundancy built in. If I hadn't had a replacement on hand, I could still be listening to music with a degraded pool until the drive arrived.

 

For those curious, this is a Seagate Ironwolf 10TB drive less than a year old. I am sure Seagate will honor their warranty with no hassles.

 

For me, the administration and learning curve to use ZFS on Ubuntu for storage has been pretty easy as well. If I can do it, anyone can do it.

No electron left behind.

I have been using ZFS on Sun hardware since the Sun days. There was a bad problem if you exported and then tried to import a root pool to another machine. That led to a kernel panic and loss of filesystem. Other than that, ZFS has been great.

 

I have a concern since ZFS has forked so much and most of the guys who wrote it are in vendor-land and some/most of their code doesn't make it into ZFS on Linux and elsewhere that things will be hopelessly incompatible. I have been waiting on FreeBSD 12 stable and I have no plans to go to 13 until all the bugs have been worked out.

 

I do agree for somebody comfortable with command line *NIX that ZFS is intelligible and not hard to manage. But I think most people are better off with a generic Linux or BSD filesystem. I would also suggest taking a long hard look at the features in the next level(s) before you zpool upgrade. The higher you go, the less compatible you will be. If you stay on a zpool version that has the features you need, you will be able to move your filesystems to another OS or box if you want.

That must have been very early in ZFS because I have moved pools from machine to machine across operating systems for awhile. The problem now is that versions/features aren't kept in sync but Linux will be around forever.

 

ZFS comes packaged in Ubuntu.
