Some wizardry: vmkfstools | virtualhobbit

Posted by jpluimers on 2019/05/24

Some wizardry: [WayBackvmkfstools | 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 [WayBackDatastore not mounted after reboot of ESXi5.5 |VMware Communities

Then found this:

That solved my problem!

# 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

When Ctrl-Click in a Windows VMware Fusion VM does right-click, when you thought you turned that off

Posted by jpluimers on 2019/05/10

A while ago, I was surprised that in a Windows VM running under VMware Fusion, the Ctrl-Click performed a right click, despite me having changed the configuration:

I was wrong, as I had forgotten I assigned the “Windows 8 Profile” tot hat VM (as it was running Windows 8.1), which had the Secondary Button still mapped to the Control+Primary Button:

vmware Fusion/Workstation/ – How can you boot from CD? – Super User

Posted by jpluimers on 2019/05/10

Basically the boot delay during startup is so short that usually you cannot even choose the boot device.

Solution: edit the .vmx file, then change this value:

bios.bootDelay = "15000"

VMFS metadata files

Posted by jpluimers on 2019/05/09

For my own ference:

disk space under VMFS-3 is organized according to four resource types. They are : blocks, sub-blocks, pointer blocks, and file descriptors. Resources are grouped into clusters, which form cluster groups. Every resource type is administered by one or a number of system files. Lets have a look at what those abbreviated file names stand for:

  • fbb.sf = file block bitmap.sf
  • fdc.sf = file descriptor cluster.sf
  • pbc.sf = pointer block cluster.sf
  • sbc.sf = sub-block cluster.sf
  • vh.sf = volume header.sfs
  • dd.sf = scsi device description.sf

The VMFS-5 uses one more system file:

  • pb2.sf = pointer block 2.sf
