October 2, 20232 yr Hey there, this morning I woke up to an error on my server. The Docker service didn't come up after the backup process this night. It seems like one of the cache drives in my application cache pool is failing. Both drive logs threw btrfs errors. After a reboot the cache and docker service are up and running again. I've read a little bit here in the forums and it seems like one of the two drives is failing. But I can't really figure out which one. Could somebody help me figuring out which one or if I have to switch both? Here the diagnostics and the smart logs of both drives. Thanks in advance! dringenet-ms-diagnostics-20231002-0808.zip dringenet-ms-smart-20231002-0822.zip dringenet-ms-smart-20231002-0823.zip Edited October 2, 20232 yr by pappaq
October 2, 20232 yr Community Expert Both btrfs pools are detecting data corruption, suggest running memtest.
October 2, 20232 yr Author Looks like we have a Winner. It was up to 25 errors when I stopped the test. I'm thinking about getting unregistered ECC memory now for replacement. My Ryzen setup should support it. I'm currently reading up about it, my knowledge about memory is a bit rusty. Would it prevent errors like these?
October 2, 20232 yr Author JorgeB, you have answered my question in another post: Just ordered unregistered ECC! Thanks for the support!
October 2, 20232 yr Author I've removed two RAM modules and ran the test again for an hour and did not get any errors. Tried now to get the server back to run until the new RAM arrives but the docker service fails to start anyway. I'm getting this error. Did the RAM corrupted something? I've got a backup of all my appdata... New diagnostics are attached. dringenet-ms-diagnostics-20231002-1402.zip Edited October 2, 20232 yr by pappaq
October 2, 20232 yr Community Expert Solution It's normal that some things will be corrupted after running some time with bad RAM, docker image can easily be recreated, pools hsould be scrubbed, any corrupt files will be listed in the syslog, and if there are any they should be deleted/restore from a backup
October 2, 20232 yr Author I am moving the files off of the App_Cache to my array, will replace the RAM on Thursday and replace the older 500GB SSD in the App_Cache for a 1TB SSD, to get an even 1TB App_Cache instead of the 1Tb + 500GB combo which resulted in 750GB. Was on my list anyway. I will recreate the docker-image then as well. How do I scrubb the two pools? Starting with the Data_cache, because the data of the other pool is currently moved. Thanks for your support!
