Gluster 5.4 is released but not yet in official repository
If like me you can not wait the official release of Gluster 5.4 with the instability bugfixes (planned for around March 12 hopefully), you can use the following repository :

For Gluster 5.4-1 :
#/etc/yum.repos.d/Gluster5-Testing.repo
[Gluster5-Testing]
name=Gluster5-Testing $basearch
enabled=1
#metadata_expire=60m
gpgcheck=0

If adventurous ;)  Gluster 6-rc0 :
#/etc/yum.repos.d/Gluster6-Testing.repo
[Gluster6-Testing]
name=Gluster6-Testing $basearch
enabled=1
#metadata_expire=60m
gpgcheck=0

GLHF

Hi, should we downgrade / reinstall our cluster? we have a 4 node cluster that's breakin apart daily due to the issues with GlusterFS after upgrading from 4.2.8 that was rock solid. I am wondering why 4.3 was released as a stable version at all?? **FRUSTRATION**
