Delete disk from stripe

[elangley]

Hello All,

I inadvertently added a disk to a volume as a stripe instead of mirror.

Is there a way to remove it and if so how?

FreeNAS 9.10.2-U6

Thanks in advance,

Nope. You will have to backup and rebuild the pool.

Bummer, that's what I thought.
Thanks.

...or upgrade to 11.2 and remove it using the CLI.

Dan, nice to know that removing a disk is possible in 11.2. What does the command for that look like?

 

[danb35]

zpool remove [-np] pool device ...
man zpool for more detail.

man zpool for more detail.

@danb35 , does that command work for a disk removal today? I just read the detailed description and could not conclude that it covered disks presently. Or is there more promising explanation somewhere else?

I believe that comes in with 11.2. It isn't there in 11.1.

I have 11.2-RC2 up and that's where I looked. Perhaps it's coming in the final release.

No, zpool remove should work in 11.2-RC2. But it only works when all vdevs in the pool are either single disks or mirrors.
