Yes, I want to keep the possibility to remove huge files from snapshots that shouldnt have been on a snapshotted volume in the first place without having to ditch the entire snapshot. > Also, If some part of the OS or tools scans through the snapshot dirs > every now and then with atime creation on, metadata grows without a > real need. I mount with noatime and nodiratime anyway, and the directory the snapshots are mounted to (/mnt/snapshots) are excluded in updatedb.conf. Any other idea which tool might scan filesystems and that might not be noticed when it's running about a five digit number of snapshots?
