June 17, 20215 yr Hi, I'm new to unraid having just converted my home media server from debian. First off I just want to thank the community, it was with the help of the forums and community apps I was able to resolve all of my questions and setup the server to my liking. All but 1 that is. The server consists of a 5 spindle disk array (with 1 parity disk), 2 SSD identical drives and 1 NVMe drive. The server only hosts docker containers, no VMs. Need to point out also that all docker containers's data/config volumes is pointing directly to "/mnt/app_data/appdata" instead of through "/mnt/user/appdata" with the consumption data on the array, I read pointing to "/mnt/user/appdata" this can cause unnecessary shfs requests in this type of setup. Originally I set it up to use the 1 NVMe as a temporary download cache for all my "Cache: yes" shares and the 2 SSD drives was in a raid 1 btrfs encrypted pool for AppData and SystemData with the shares set up "Cache: Only". I noticed the 2ssd drives having constant write actions even when the server was idle. After looking through the forums I came to the conclusion it might be due to the btrfs encrypted volumes causing the writes and set out to split the volumes and change it to xfs encrypted volumes, with a physical backup to be made instead of the raid 1 parity. After the change I have the NVMe for AppData and SystemData, 1xSSD for temporary data and 1xSSD for the backups of the nvme, with all of the volumes being xfs encrypted. The problem is that there is still constant writing activity (13'000 write commands in 30min) happening while the server is idle and still only on the AppData/SystemData shares. It doesn't seem to be writing too much actual data, but there is write commands happening and I'm worried about the longevity of the SSDs if this goes on too long. I've gone through all my docker logs and even stopped all containers but the writing continues. Anyone have an idea of where next to look or try to resolve the issue? My only thought would therefore be that it has to do with either the docker image or the libvirt image files. regards Edited June 17, 20215 yr by NLynzaad clarification
