June 10, 20242 yr https://imgur.com/a/vctkeTG I thought it would just re-balance itself? https://imgur.com/a/q9NqeOl I also noticed in this FAQ did pretty much what I did. Stop Array Set cache drive 3 to no disk Start array again. Instead I get an error. Edited June 10, 20242 yr by EcN
June 10, 20242 yr Community Expert Solution You can only remove a drive from a multi-drive pool if all aspects of it are set to a RAID1 profile or something similar. According to your screenshot this is not the case as metadata, etc are set to Single profile.
June 10, 20242 yr Community Expert 48 minutes ago, itimpi said: metadata, etc are set to Single profile. And they should never be like that, unless it started as a single device and the metadata failed to balance to raid1 when more devices were added.
June 11, 20242 yr Author Thanks, I may have started with a single drive, then immediately added a second one? Then added third one a week or so later. I assume the fix here then is to move all shares off cache, set new config and add the drives/drives back to cache. What's the correct procedure to add to a cache pool and what do I look at to make sure it's balanced correctly?
June 11, 20242 yr Community Expert You can first try to re-balance to raid1 using the GUI, click on the pool and scroll down to the balance option, then post new diags.
June 11, 20242 yr Author Thanks, I'll try that next time if I run into the same issue. Ended up making a new config already.
