Ugh, After having rebooted the 3-way HCI Cluster everything came back online, all the gluster volumes are online, no split-brain info detected. Also they are mounted on all nodes. The Volumes, Domains and Disks are all marked green in the Engine. Launching a VM fails with "VM test01 has been paused due to storage I/O problem." A md5 sum of an uploaded ISO image from all three mounted cluster members yield the same md5, so does the source file on my PC. Creating a new VM and attaching that ISO fails: The ISO is not readable (says the vm console). The Disk Image from the test01 vm seems sounds (file has correct size, file-tool shows correct magic header), other files (configs) are readable. I did complete cluster reboot etc. gluster> volume heal vms info split-brain Brick node01:/gluster_bricks/vms/vms Status: Connected Number of entries in split-brain: 0 Brick node02:/gluster_bricks/vms/vms Status: Connected Number of entries in split-brain: 0 Brick node03:/gluster_bricks/vms/vms Status: Connected Number of entries in split-brain: 0 Brick node01:/gluster_bricks/vms/vms Status: Connected Total Number of entries: 0 Number of entries in heal pending: 0 Number of entries in split-brain: 0 Number of entries possibly healing: 0 Brick node02:/gluster_bricks/vms/vms Status: Connected Total Number of entries: 0 Number of entries in heal pending: 0 Number of entries in split-brain: 0 Number of entries possibly healing: 0 Brick node03:/gluster_bricks/vms/vms Status: Connected Total Number of entries: 0 Number of entries in heal pending: 0 Number of entries in split-brain: 0 Number of entries possibly healing: 0 How would I fix this issue?
