[Gluster-users] Files not healing & missing their extended attributes - Help!

You have not even talked about the volume type and configuration and this issue
would require lot of other information to fix it.

1 - What is the type of volume and config. 
2 - Provide the gluster v <volname> info out put 
3 - Heal info out put 
4 - getxattr of one of the file, which needs healing, from all the bricks. 
5 - What lead to the healing of file? 
6 - gluster v <volname> status 
7 - glustershd.log out put just after you run full heal or index heal

attributes - Help!

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.

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.
The healthy files on the bricks do have their extended attributes though. 

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.

I've got 16 hours to get this sorted before the start of work, Monday. Help!

[Gluster-users] Files not healing & missing their extended attributes - Help!

Hi Ashish,

The output is below. It's a rep 2+1 volume. 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).

=====================
Okay, so actually only the directory ha_agent is listed for healing (not
its contents), & that does have attributes set.

Many thanks for the reply!
