Hello,
My ESXI 5.5 server lost power and upon reboot it will not mount the datastore. I am able to see the LUN under devices, however, when I try to re-add the datastore the option to "Assign a new signature" or "Keep existing signature" is grayed out and I'm left with teh format the disk option which is not fesible as it will delete all existing data on the disk.
I tried to force mount the volume and I get the error:
# esxcli storage vmfs snapshot mount -l "192.168.20.125-datastore"
Unable to mount this VMFS volume due to some extents missing
In , tail -f /var/log/vmkernel.log I see;
Device naa.600508b1001c9c37879d18027a0678e1:1 detected to be a snapshot:
When I run esxcli storage vmfs snapshot extent list, I see:

The datastore is a 8.7TB datastore and I did not create any extents so it seems that ESXI does this automatically. I was under the impression that in 5.5 it would only use 1 extent up to 64TB. In any case, I am trying to recover my VMs/data. Is there anything I can do to recover them or am I completely at a lost?
