[Gluster-users] gluster3.3.0 cause the ext4 system error then the linux(2.6.32-220.el6.x86_64) kernel panic...

[Viktor Villafuerte]

Same here,

Had ext4 in production with distributed replicated setup and after
adding 3rd set of replicas (1x1) things went really really bad.. This
was with 2.6.32.xxx kernel and Gluster 3.2.5

Had to rebuild with XFS and upgraded Gluster to 3.4.2 yesterday and all
seems good so far..
