Hello list readers, I am doing rsync backups based on Mike Rubels recipe (mikerubel.org/computers/rsync_snapshots). I am creating lvm snapshots of partitions whose contents changes fast. In order to verify if evyerthing went ok, I do md5sum checks on all files and everytime some files are failing the test. Here is a list of them: ./amavis/db/__db.001: FAILED ./amavis/db/__db.002: FAILED ./amavis/db/__db.003: FAILED ./amavis/quarantine/spam-Tj3tsKAU7G3c.gz: FAILED ./amavis/quarantine/spam-VyKl+vwlBxlY.gz: FAILED ./amavis/quarantine/spam-pAMwYjbMNhuP.gz: FAILED ./amavis/quarantine/spam-36fTxT+IWOPS.gz: FAILED ./amavis/quarantine/virus-tvUARLx2txFB: FAILED ./amavis/quarantine/spam-Zli5v0qZSomA.gz: FAILED At first I wasn't stopping services on that machine, because I thought that taking snapshots with lvm would give me a consistent state of the filesystem. Ok, maybe I really have a consistent state and rsync is to be blamed. However, I also stopped amavisd-new and all other services before I did the lvm snapshot and I still get the above failures. Any ideas why this happens and how I get rid of the errors? TIA and kind regards, Timo
