Hi, I just tested power cut on the test system: Cluster with 3-Hosts each host has 4TB localdisk with zfs on it /zhost/01/glu folder as a brick.
Glusterfs was with replicated to 3 disks with arbiter. So far so good. Vm was up an running with 5oGB OS disk: dd was showing 100-70MB/s performance with the Vm disk. I just simulated disaster powercut: with ipmi power-cycle all 3 hosts same time. the result is all hosts are green up and running but bricks are down. in the processes I can see: ps aux | grep gluster root 16156 0.8 0.0 475360 16964 ? Ssl 08:47 0:00 /usr/sbin/glusterd -p /var/run/glusterd.pid --log-level INFO What happened with my volume setup?? Is it possible to recover it??
