Remove device in raidz1 pool

1738285

Hello,

I run a ZFS raidz1 pool under Solaris 11.1 which has one failed device that has to be replaced. The storage appliance is about 5 years old, no warranty or service contract, and spares are getting expensive...

Is it possible to remove (not replace) the failed disk-device, then rebuild the pool, thus making the pool smaller? Or do I have to backup my data, and set up a new pool?

Thanks in advance,

Robert

Hi.

You can not decrease pool size.

You need backup data, build new pool and restore data.

But check, may be you have free hotspare disks.

Hi,

Can you please show the pool detail with "zpool status -v poolname" ?

If you need to replace 1 faulty disk...you can assign new Lun/disk to your OS and use zpool replace command.
