The only problem at the moment is that arbiter brick offline. You should only bother about completion of maintenance of arbiter brick ASAP.Bring this brick UP, start FULL heal or index heal and the volume will be in healthy state.
Doesn't the arbiter only resolve split-brain situations? None of the files that have been marked for healing are marked as in split-brain.
The arbiter has now been brought back up, however the problem continues.
I've found the following information in the client log:

As you can see from the logs I posted previously, neither of those two files, on either of the two servers, have any of gluster's extended attributes set.
The arbiter doesn't have any record of the files in question, as they were created after it went offline.

How do I fix this? Is it possible to locate the correct gfids somewhere & redefine them on the files manually?
Cheers,

The arbiter is offline for maintenance at the moment, however quorum is met & no files are reported as in split-brain (it hosts VMs, so files aren't accessed concurrently).

Subject: Files not healing & missing their extended attributes - Help!______________________________I've got 16 hours to get this sorted before the start of work, Monday. Help!I'm guessing that perhaps the files somehow lost their attributes, and gluster is no longer able to work out what to do with them? It's not logged any errors, warnings, or anything else out of the normal though, so I've no idea what the problem is or how to resolve it.The healthy files on the bricks do have their extended attributes though.I checked the listed files' extended attributes on their bricks today, and they only show the selinux attribute. There's none of the trusted.* attributes I'd expect.Hi Guys,I had to restart our datacenter yesterday, but since doing so a number of the files on my gluster share have been stuck, marked as healing. After no signs of progress, I manually set off a full heal last night, but after 24hrs, nothing's happened.
The gluster logs all look normal, and there're no messages about failed connections or heal processes kicking off._________________
