Two replicated volumes with online update, upgraded clients first and followed by servers upgrade, "stop glusterd, pkill gluster*, update gluster*, start glusterd, monitor healing process and logs, after completion proceed to the other node" You should first upgrade servers and then clients. New servers can understand old clients, but it is not easy for old servers to understand new clients in case it started doing something new. check gluster logs for more information. -- Respectfully Mahdi A.

I experienced filesystem corruption on several but not all VMs (KVM, FUSE) stored on Gluster during Gluster upgrade. After upgrading one of two nodes, I checked peer status and volume heal info, everything seemed fine so I upgraded second node and then two VMs remounted root as read-only and dmesg contained I/O errors. This did not happen in the past while following the same upgrade procedure. Documentation mentions only upgrades to higher minor version. Is there a recommended way to upgrade or did I do something wrong that should be avoided?
