Some wizardry: vmkfstools | virtualhobbit

Posted by jpluimers on 2019/05/24

Some wizardry: [WayBack] vmkfstools | virtualhobbit.

This includes:

  • finding which VMFS partitions are there the hard way
  • initialising partitions from known good data
  • vmkfstools -V (yes, capital V is for VMFS rescan, as lowercase v is for verbose)

Found after reading [WayBack] Datastore not mounted after reboot of ESXi5.5 |VMware Communities

Then found this: [Wayback] VMware Knowledge Base: Performing a rescan of the storage on an ESXi host (1003988); Using the ESXi Command Line Interface

…

  1. To search for new VMFS datastores, run this command:
vmkfstools -V

Note: This command does not generate any output.

That solved my problem!

# vmkfstools -V
# esxcfg-volume --list
Scanning for VMFS-3/VMFS-5 host activity (512 bytes/HB, 2048 HBs).
VMFS UUID/label: 532cd010-6e8c01d1-45be-001f29022aed/Raid6SSD
Can mount: Yes
Can resignature: Yes
Extent name: naa.600605b00aa054a0ff000021022683ae:1 range: 0 - 1830143 (MB)
# esxcfg-volume --mount 532cd010-6e8c01d1-45be-001f29022aed
Mounting volume volume 532cd010-6e8c01d1-45be-001f29022aed

And there it was:

# df -h
Filesystem   Size   Used Available Use% Mounted on
...
VMFS-5       1.7T   1.6T    169.6G  91% /vmfs/volumes/Raid6SSD
...

Note you can mount non-persistent (--mount) or persistent (--persistent-mount) by both UUID and label, so there are four choices for mounting:

esxcfg-volume --mount UUID
esxcfg-volume --mount label
esxcfg-volume --persistent-mount UUID
esxcfg-volume --persistent-mount label
