Hi,
I had an issue booting a host from USB due to corruption so re imaged the USB stick. On booting I had to manually mount one datastore (the server has 3 local HDDs, 2 in a mirrored pair and one not in an array) but the second datastore will not mount. The datastore is not visible in the webclient, but I can see it as a snapshot (oddly) via CLI:
[root@localhost:~] esxcli storage vmfs snapshot list
59beb848-9069b44e-64b3-00fd45fd5450
Volume Name: DATA
VMFS UUID: 59beb848-9069b44e-64b3-00fd45fd5450
Can mount: false
Reason for un-mountability: duplicate extents found
Can resignature: false
Reason for non-resignaturability: duplicate extents found
Unresolved Extent Count: 2
And again as a volume:
[root@localhost:~] esxcfg-volume -l
VMFS UUID/label: 59beb848-9069b44e-64b3-00fd45fd5450/DATA
Can mount: No (duplicate extents found)
Can resignature: No (duplicate extents found)
Extent name: t10.ATA_____WDC_WD20EZRX2D00DC0B0_________________________WD2DWCC1T1033575:1 range: 0 - 1907455 (MB)
Extent name: t10.ATA_____WDC_WD20EZRX2D00DC0B0_________________________WD2DWCC1T1090546:1 range: 0 - 1907455 (MB)
When I try mount the "snapshot" I get:
[root@localhost:~] esxcli storage vmfs snapshot mount -l DATA
Unable to mount this VMFS volume due to duplicate extents found
I can't try and mount the datastore as a volume as I get:
[root@localhost:~] esxcli storage filesystem mount -u 59beb848-9069b44e-64b3-00fd45fd5450
No volume with uuid '59beb848-9069b44e-64b3-00fd45fd5450' was found
I've read various posts online addressing similar issues, usually to do with SAN storage as apposed to local, some suggesting to resignature the volume but I also get an error around duplicate extents when I attempt that.
Does anyone have any ideas how to resolve the issue? I'm at a dead end.
Thanks.
