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

[Kingsley]

Thanks for that Vijay. I installed gluster via yum, but yum check-update
reveals no updates to download. How should I apply those patches, or ...
do you have a rough idea when 3.6.3 will be available? I'd like to roll
our cluster out into production soon but would prefer to get this fixed
first.

Cheers,
Kingsley.
