[Gluster-users] File\Directory not healing

[David Dolan]

Just to confirm I've got this correct?

So I'll move the directory with the different gfid on the Arbiter brick to
somewhere else
I then touch this directory on another brick(software is not sensitive to
atime update)

I guess the healing should then take place automatically?

Thanks
David
