Hi all, the past few days I've noticed that my docker containers have been failing, whether adding a new container, trying to restart a container, etc. I've figured that my cache drives are starting to fail (these are 11-12 year old Kingston drives), because I'm seeing corruption errors for both drives on the the BTRFS pool. (even increased a bit).

SMART tells me that they're fine, however I'm not 100% convinced on it.

I am currently trying to move the docker files out of it with Mover however it's not working properly, not all the files are being moved out of it (I'm thinking i might need to use MC, or file manager?)

I've already ordered replacements however would like a 2nd opinion from the community. Am i overreacting and just need to recreate docker.img or are the drives at the point of replacement?

I've not touched the hardware on these since I added another array drive earlier in the summer, so id highly doubt its that.

The Mover somehow duplicated files when copying to my array, it didn't fully move them. Luckily, i had a spare external drive that I just copied the folders to, however not all of them were able to copy, it was complaining about input/output error. When i looked at the screen through my jetkvm, it had more errors about BTRFS. I think I'm confident that the drives are at the point of replacement. As of writing this, the corruption errors increased to 153.

Btrfs detecting data corruption is most often bad RAM, start by running memtest.

Well, I was really hoping it wouldn't get to that, but started a memory test while waiting for the new drives to arrive...

I guess have to get new RAM sticks as well...

Wait hold on I just remembered I had XMP on, let me try again with it off, hopefully that'll tell me something.

Nevermind, looks like it still errored out. Time to play the game of figuring out which is the bad stick.

Alright, I'm still not done the testing but it appears that ram stick 3 has issues. I can probably run in a 1x32GB and 2x16GB configuration, will not be ideal, but i can still get 64GB of RAM for the time being while I source another 32GB stick.

I will probably still do a drive replacement however, since it's already been shipped from Amazon and it'll arrive in a few hours, might as well get that out of the way and to ensure that BTRFS doesn't go corrupt again. Any tips for a new BTRFS pool would be great.

Appreciate the assistance though, I was hoping the RAM would last a lot longer but I guess it being online 24/7 doesn't really help it that much...

Update.

Swapped the cache pool, recopied the files directly to the pool. All dockers seem to be working for now. Had a bit of a kerfuffle when trying to delete the duplicates.

Hopefully it's stable for the week.
