Hi, I tried to do a quick search to see if something in proxmox uses access time and might have problems with noatime, but I couldn't find anything for sure.
I found many posts where noatime is used on zfs, but I'm not sure if done with the certainty that it does not cause any unforeseen events.
relatime which is default should not cause problems and reduces extra writes to data but on cow filesystems (btrfs and zfs) with snapshots it has an impact on metadata when you have snapshots, noticeable if there are many, noatime will avoid this.
I was therefore asking this question, mainly to see possible improvements to the btrfs support, which is limited for now.
For additional storage of data only and the default storage subvolume I think it can be enabled without problems and if there were for atime use I would have found some posts about it in the search, a confirmation would be useful though.
While where I have doubts is mainly its use in the root, so I ask if anyone can tell me if there are parts of proxmox in the root or other programs used that use access time
