[Users] [3.2-el6] corrupted disk after snapshot removal
Hi, I've run into some disturbing situation recently with my production ovirt-3.2-el6. Planned an upgrade for one of my vm's app, so i've took live snapshot, did application upgrade. Upgrade went fine, so I had no need in taken snapshot - I've shutdown vm and deleted snapshot via admin interface. When task was completed (took about 40mins) I've tried to start vm - but its OS didnt start - "no boot disk found". Disks tab in admin interface shows 'actual size' = 1Gb, fdisk from livecd shows no partitions at all. It seems snapshot removal somehow corrupted vms disk. What went wrong and how to avoid this in future? logs in attach ovirt-engine.noarch 3.2.2-1.1.el6 vdsm.x86_64 4.10.3-16.el6 Storage domain type is FC -- Yuriy Demchenko

Well, I restored vm from backup. I couldn't find the cause of problem from logs and didn't yet had chance to do more tests to reproduce it, as my test env currently occupied... Yuriy Demchenko On 11/05/2013 01:30 PM, Itamar Heim wrote:
