Hi,while verifying the heal information for one of the hosted bricks I found out a few entries were not properly in sync anymore (I wondered how that could be possible as just one node is serving the data and the other is there as a backup and no, I had no downtime that could have made the gluster fuse client to switch to the other available node), after following the documentation at [1] I removed both the offending files and the respective hard links from the .glusterfs directory, (I found the '-samefile' flag of 'find' very handy for this job) but then I still had a few standing entries that would not report what file they were affecting but just the relevant gfid, in particular:sudo gluster volume heal mailman infoBrick brick01:/mnt/gluster_volumes/mailman/<gfid:7220e73e-d0c6-4f03-a541-b59fa713db7b><gfid:a58e2209-0281-46e6-91d7-44e3fb06d6fa><gfid:c5bd1fe9-a19a-4b32-a5a5-83f9f6d5d425><gfid:5985ae98-78c0-4b84-840a-7149093e79dc>Number of entries: 4Brick brick02:/mnt/gluster_volumes/mailman/7220e73e-d0c6-4f03-a541-b59fa713db7bNumber of entries: 1The relevant log entries:[2014-08-17 21:04:07.747654] E [afr-self-heal-common.c:233:afr_sh_print_split_brain_log] 0-mailman-replicate-0: Unable to self-heal contents of '7220e73e-d0c6-4f03-a541-b59fa713db7b' (possible split-brain). Please delete the file from all but the preferred subvolume.- Pending matrix: [ [ 0 4 ] [ 2 0 ] ]Am I in presence of another split brain situation? additionally the process that should be accessing the files I touched is reporting me an "Input/Output" error when trying to write to the glusterfs-mounted directory. (not on the whole brick but just on the directory that had the original split-brain)Thanks in advance!
