I only checked cursorily with 'ls thisdir' and 'ls thatdir' to see if things looked OK and they did. But it can't hurt to also try checksumming some (non-)random files, so I did that too. They all match. Note: I did the checksums on /gfsroot/volname/.glusterfs/hex/hex/uuid and not on the fuse mounts, partly for speed and partly to eliminate the risk of the client reading from a non-local brick: count=0; for f in `find /vol/gfs/gv0/.glusterfs/[0-9a-f][0-9a-f]/ -type f`; do count=$(($count + 1)); echo $count; if [ $(($count % 10000)) -eq 0 ]; then sha256sum $f >>sha`hostname`; fi; done BTW, I saw an error in the documentation of my previous mail. Where it says "rsync -vva /datasource/blah 127.0.0.1:gv0/" it should say "rsync -vva /datasource/blah /mnt/fuse/gv0mountpoint/". Sorry for that. ________ Community Meeting Calendar: Schedule - Every 2nd and 4th Tuesday at 14:30 IST / 09:00 UTC Bridge: https://meet.google.com/cpu-eiue-hvk Gluster-users mailing list Gluster-users@xxxxxxxxxxx https://lists.gluster.org/mailman/listinfo/gluster-users
