[Gluster-users] How to make sure self-heal backlog is empty ?

[Ben Turner]

You can try kicking off a client side heal by running:

ls -laR /your-gluster-mount/*

Sometimes when I see just the GFID instead of the file name I have found that if I stat the file the name shows up in heal info.

Before running that make sure that you don't have any split brain files:

gluster v heal your-vol info split-brain

If you do have split brain files follow:

HTH!
