ESX: Recover from expanded disk with existing snapshot or corrupted snapshots
Wednesday, November 14th, 2007I had a nasty shock this week with ESX3.
I was going about expanding virtual disks and reallocating resources for one client. Now, I have done this MANY times, so I thought that “the 2 day old backup is sufficient” and did not wait 3-4 hours for a new backup, right before what will be a 10 min task.
I went to expand the virtual disks from the COS and noticed that there were some “Virtual-Disk-000001-delta.vmdk” and “Virtual-Disk-000001.vmdk” files present.
“Oh, a snapshot is here for some reason..?”, I pondered. I then went into the VI3 management console, drilled down to said VPS and went to the snapshot manager, expecting to find a snapshot and then simply commit it to the main disk so I could get back to expanding.
