No, the issue is probably dom_md/ids accessed by sanlock, but removing
files
accessed by sanlock will not help, an open file will remain open until
sanlock
close the file.
I'm testing this with volume snapshots at the moment, so there are no
processes accessing the new volume.
Did you try to reboot the host before installing it again? If you did and
you
still have these issues, you probably need to remove the previous
installation
properly before installing again.
Adding Simone to help with uninstalling and reinstalling hosted engine.
The Hosted-Engine database had been corrupted and the restore wasn't
running correctly, so I installed a new engine on a new server - no
restores or old data. The aim is to import the old storage domain into the
new Engine & then import the VMs into the new storage domain.
My only problem with this is that there appear to be some file based leases
somewhere that, unless I manage to locate & delete them, force me to wait
for the leases to timeout before I can import the old storage domain.
To minimise downtime, I'm trying to avoid having to wait for the leases to
timeout.
Regards,
Doug
