1 of 2 Cache Drives has failed.

Now I can't seem to replace it as it keeps on saying it is unmountable and the file system doesn't seem to exist. I have tried the first part on here to no avail but I can't get the second part to work. Any help would be greatly appreciated.

The pool, or at least some part of it, was not redundant:

 

Jul 13 01:45:31 Tower kernel: BTRFS warning (device sde1): chunk 6170883391488 missing 1 devices, max tolerance is 0 for writable mount
Jul 13 01:45:31 Tower kernel: BTRFS warning (device sde1): writable mount is not allowed due to too many missing devices

 

Is the old device still available or it's completely dead?

[GreenGoblin]

The old drive is completely dead for what I can tell. I removed it from the case thinking I could just replace it with another 2tb SSD. or is that not the case? as of right now I'm still getting the error for file system not existing. I have been away so not been able to deal with this for a while.

You can try these recovery options here but most likely at least some data will be incomplete.

Hi @JorgeB,

 

Thanks for that.

 

I have been away so I'm now coming back to this and I see this:

Any ideas on how I should proceed? I have a spare SSD connected and unassigned which has the data form the cache drives backed up on it.

Suggests copying what you can/need from the pool and re-formatting.
