[Gluster-users] gluster 3.6.2 "no data available" error - selinux?

[Kingsley]

Hi,

I've got a cluster running on CentOS 7 and Gluster 3.6.2 and using the
fuse client on the clients, which are running the same OS and Gluster
version as the servers. There are 4 servers with a brick each, running 4
way replication.

On a client, each time I create a file or chmod it (it may happen with
other operations but I haven't tested those), I get an error in the logs
on the servers, although on the client the file operation appears to
work ok. I get two lines like this:

[2015-01-30 10:46:06.889661] E [marker.c:2562:marker_removexattr_cbk] 0-gv0-marker: No data available occurred while creating symlinks
[2015-01-30 10:46:06.889685] I [server-rpc-fops.c:693:server_removexattr_cbk] 0-gv0-server: 29800868: REMOVEXATTR /testing/thingy (0460a967-d1de-462b-be97-d6e5736c89c4) of key security.ima ==> (No data available)

The bricks are within /data on the servers; "mount" says this
about /data on the servers:

/dev/md123 on /data type xfs (rw,relatime,seclabel,attr2,inode64,sunit=1024,swidth=3072,noquota)

This post says something about selinux being required in some
circumstances:

Do I need to set up selinux on the fuse clients? I've not really played
with selinux before so would prefer to avoid that learning curve at this
moment unless it's necessary.
