I did a very stupid thing: my cache pool has 1 TB nvme + 500GB SDD, total usable space was 1.5TB because it was on single mode.

 

I had plans on replacing the 500GB SSD by a 1TD SDD - I can't add more disks to the cache as I don't have SATA ports left on the server.

The space left on the disk was about 600 GB, meaning I had 900GB being used. When I converted the pool to raid1 the total space became 750GB with full usage, ie, 0% free space, so all dockers have stopped as there is no space.

 

You can't imagine my face... I somehow thought I had two disks of 1TB so my pool would be from 2 TB to 1 TB.

 

Anyway, what's done is done. I have backups of everything of course... except Plex because it's huge, but now I'm thinking I should have done at least a backup a month... as that would be a pain to rebuild. Well the files are still on the

 

I've copied the whole cache disk into the array just to salvage what I can at a later stage, but using MC I get some read errors, I guess from files that are now corrupted and irrecoverable.

 

I can't do anything other than copying from the cache, so what is your suggestion?

 

I've added another disk to the cache to see if that solves anything but actually it didn't increase on size nor changed anything at all. The options to scrub or migrate to single, raid, balance, etc don't do anything at all.

 

Could someone give me some guidance on how to try to solve this mess?

Thanks!

Pool if failing to balance because it's running out of space, you can copy the data and redo the pool or try to cancel the balance, free up some space, then continue, I can post more detailed instructions for the latter if you want to try that.

I can't delete any data because it's read-only, because it's full but the fact that it says is using less space than it actually has is concerning.

 

I've copied all data already.

 

If I redo and copy the data back, would the dockers appear there? Where is the actual docker configuration stored?

 

I have the app data folder backup from the CA plugin but that won't create the actual dockers if I understand correctly.

 

Right now docker service won't initiate but I've stopped anyway. 

 

Thanks

first to avoid that, then free up some space.

 

But if you have already copied the data you can just re-format and then restore, if you restore the appdata you can then use CA to restore the containers:
