Cache drive unmountable - how to save Dockers?

3 posts in this topic Last Reply

Hello, I have a 128GB SSD cache drive that I pretty much only use to hold my docker stuff (plex metadata, etc)

I added two disks to the array, as my Disk 1 (HDD) is failing, and so I wanted to replace that disk and also add some more storage while I was in there.

 

I may have jostled the cable for the SSD a little while I was installing it, but when I initially booted back up everything was 100%. All dockers running, the two new drives recognized as unassigned and I started my preclear. For the next 25 hours everything stayed normal while the pre-clear ran.

 

So last night, I stop the array and remove Disk 1, setting it to be a different disk. (One of the unassigned devices I precleared).. The array began the parity rebuild and everything seems to be going peachy. However, this morning I noticed the cache drive is unmountable...  I haven't physically opened the case since the drive WAS mountable... I really need the information from my dockers!!!

 

I only have a Windows PC and a Mac besides the server - what is the best way (If its even possible?) to save my docker information?

 

 

Another small thing - when I started the array rebuild, the "READS" on my unmountable SSD was like 600... now, it is up to 18,089, so it is somehow doing reads to the disk... I don't even know!!

 

Please help! (Rebuild will be done in 11 hours)
