All, I have a Datastore that will not mount. It is on a HP P2000 and VMware (5.5.0 u3b) on the host required a rebuild after corruption. Note the store would not mount previously. 9 out of 10 stores mount and are visible in VMware.
I have already tried to reset the partition table - using partedUtil. following the guidance here - VMware Knowledge Base
~ # partedUtil getptbl /vmfs/devices/disks/naa.600c0ff00014c353c7c00f5001000000
gpt
497976 255 63 8000000000
1 2048 7999997951 EBD0A0A2B9E5443387C068B6B72699C7 linuxNative 0
getUsableSectors returned - 7999999966
Current status -
~ # partedUtil getptbl /vmfs/devices/disks/naa.600c0ff00014c353c7c00f5001000000
gpt
497976 255 63 8000000000
1 2048 7999997951 AA31E02A400F11DB9590000C2911D1B8 vmfs 0
Note - have tried both 7999997951 and 7999999966 for usable sectors
The drive does not show within /vmfs/volumes yet the device shows as mounted via the vSphere Client, under storage adapter, Operational State.
Errors in the kernel log show - 'No FS driver claimed device 'naa.600c0ff00014c353c7c00f5001000000:1': Not supported'
Calculated value for usable sectors was - 7999984439 - and this also fails.
This volume is 4TB.
Any ideas? Many thanks.
