Hi, well at this stage it looks very strange: * it looks like the disks are really not on the storage domain - the lv for the vm you are attemtping to start (From the previous mail's logs) is not visible at all. * did something happen to the storage server itself/is it possible that things were deleted from the storage itself? (maybe you deleted the vms' disks?) * On the problematic node I see that the lvm command gave some errors regarding missing devices: /dev/mapper/360a9800042415569305d434565795a54: read failed after 0 of 4096 at 10737352704: Chyba vstupu/výstupu /dev/mapper/360a9800042415569305d434565795a54: read failed after 0 of 4096 at 10737410048: Chyba vstupu/výstupu /dev/mapper/360a9800042415569305d434565795a54: read failed after 0 of 4096 at 0: Chyba vstupu/výstupu /dev/mapper/360a9800042415569305d434565795a54: read failed after 0 of 4096 at 4096: Chyba vstupu/výstupu * Is the domain a single LUN or multiple LUNs? what is the output of # multipath -ll # vgs could you attach the full vdsm log from the problematic host maybe?

lvs ce77262f-8346-42e5-823a-bd321f0814e7 Hello,
it is ISCSI domain. All nodes are problematic. lvs output: http://fpaste.org/76058/ I restarted problematic node but it did not help. So I removed it from cluster, but many other VMs on ther nodes are dead (can not run, or can not boot from disk because they do not see it). About 5% of VM we were able to export or restart to stable status
