[Gluster-users] Rsync in place of heal after brick failure

[Tom Fite]

Hi all,

I have a very large (65 TB) brick in a replica 2 volume that needs to be
re-copied from scratch. A heal will take a very long time with performance
degradation on the volume so I investigated using rsync to do the brunt of
the work.

The command:

rsync -av -H -X --numeric-ids --progress server1:/data/brick1/gv0
/data/brick1/

Running with -H assures that the hard links in .glusterfs are preserved,
and -X preserves all of gluster's extended attributes.

I've tested this on my test environment as follows:

1. Stop glusterd and kill procs
2. Move brick volume to backup dir
3. Run rsync
4. Start glusterd
5. Observe gluster status

All appears to be working correctly. Gluster status reports all bricks
online, all data is accessible in the volume, and I don't see any errors in
the logs.

Anybody else have experience trying this?

Thanks
-Tom
