[Gluster-users] Solving healing and split-brain problems

[Pranith Kumar Karampuri]

hi Alan,
      Could you please send me
1) logs from all the machines.
2) heal info full output
3) gluster volume info <volname> output.
4) "getfattr -d -m. -e hex <backend-brick-dir>/file-path" and "stat <backend-brick-dir>/file-path" outputs for the files on which the self-heals are attempted. 

Pranith
