January 13, 20251 yr Hello, the dockers will not start. I ran Fix Common Problems and there is an error "Unable to write to cache Drive mounted read-only or completely full." It says that this means the drive is currently full or the mounted read-only. The drive has a lot of free space and I'm uncertain how to check if the drive is set to read-only. This happened while I was watching plex, so I'm uncertain how something could have been changed. I've included 2 screen captures and the diagnostics file. Any help is greatly appreciated, I am a beginner user of Unraid. tower-diagnostics-20250113-0129.zip
January 13, 20251 yr Community Expert The pool has filesystem issues, and since btrfs was detecting data corruption, start by running memtest.

January 22, 20251 yr Community Expert You shouldn't even attempt to run any computer unless RAM is working perfectly. Everything goes through RAM. The OS and other executable code, your data, everything. The CPU can't do anything with anything until it is loaded into RAM.
January 22, 20251 yr Community Expert You should do whatever is necessary to have zero errors in memtest. Try memtest with only one stick, if it passes, try another, etc. If you are overclocking, don't. Your data is more important than marginal speed gains.
January 23, 20251 yr Author I tested each one separately and they all passed except for one. I started the server with 2 sticks installed and the dockers still do not start. I still get the same message in "Fix Common Problems"
January 23, 20251 yr Community Expert Fixing RAM is the first step in being able to fix other problems. Fixing RAM won't fix the damage already done to your data from the bad RAM. Post new diagnostics
January 23, 20251 yr Community Expert Probably best if you disable Docker and VM Manager in Settings until you get cache working again. The related shares (appdata, domains, system) aren't really configured in the best way anyway. You will probably have to reformat cache. Mover won't work on read-only filesystem, so if you need any of its data you will have to try to copy it off.

Ideally, these user shares would have all files on a pool (such as cache), with no files on the parity array, so Dockers/VMs will perform better, and so array disks can spin down since these files are always open. 52 minutes ago, trurl said: disable Docker and VM Manager in Settings until you get cache working again. and you get those shares where they belong.
January 29, 20251 yr Author I was able to reformat the cache drive and I got the dockers set back up. All the dockers are running very slow, can you look at the config file to see if you see any issues? tower-diagnostics-20250129-1112.zip

These shares have files on the array, and in fact, are currently configured to be moved to the array. Disable Docker in Settings. Set these shares to Primary:cache; Secondary:array; Mover action:array->cache Go to MAIN - Array Operations, click Move, wait for it to complete. Then post new diagnostics.
January 30, 20251 yr Community Expert appdata still has some files on the array. Mover won't overwrite files, so if there are duplicates, you will have to clean those up yourself. Dynamix File Manager plugin (built-in on Unraid v7) will let you work with files and folders directly on the server from the webUI.
January 30, 20251 yr Author Thank you for all the help! I installed Dynamix File Manager and I found one appdata folder in one of the drives and deleted it. Here is the latest diagnostics. tower-diagnostics-20250130-1101.zip
January 30, 20251 yr Author It seems to be working better, but Radarr and Sonarr seems a bit sluggish compared to how they use to run.
