Swapping cache pool drives

Featured Replies

Hey all!

 

I just bought 2 new 1TB NVME SSDs for an existing cache pool in unraid. The old ones are also 1TB each and M.2.

Since VMS and dockers are running from that cache pool, i wanna make sure it just works.

Is it correct, that I can simply swap 1 of the drives, and on reboot, select the new drive, in the dropdown where it says missing disk. Start the array, let it sync the old drive to the new.

Rinse and repeat with drive 2, when the sync is done?

Yes that's fine, assuming the current pool is redundant, also make sure you're using the current stable, this didn't always work correctly with older releases.

Am on 6.9.2, and yes the pool is redundant :)

Upgrade to v6.11.1 first, v6.9 didn't stop the array from auto starting with a missing pool device, though you could add it later, and don't remember if there were other issues.

I had some trouble with a disk suddenly not being recognized, and when it booted up it didnt start the array, and i had the option of selecting the missing disk.

It did it for the array, not for pools until v6.10

It was the second m.2 NVME drive in the cache pools ;)

 

But ty for the info, will try to grow balls enough to try to update UNRAID 🥴
