- placatedmayhem 5y agoI do wish access times were disabled by default. In my experience, they don't generally provide any useful information, but place unneeded stress on the storage.
- chasil 5y agoTheir original purpose was to help administrators identify unused files to migrate to auxiliary storage. This is discussed in a BtrFS post on the atime impact to snapshots (quite harmful). Definitely mount BtrFS with noatime when snapshots are in use (likely best with ZFS also). https://lwn.net/Articles/499293/ https://lwn.net/Articles/499293/
