    Yes, those set.N items are related to the install locations HD1.N. If you want to destroy one, you can issue "tmsh delete sys software volume HD1.N", either in the guest or the host, wherever you're trying to eke out more free disk space.

Thanks Jim, for your help.

Lvscan command returns this:

[root@XXX:Active:Standalone] config  lvscan -av
    Finding all logical volumes

  ACTIVE            '/dev/vg-db-sda/set.3._var' [3.00 GB] inherit

Do you know all these "set.*_*" volumes are all necessary? Can the "missing" space coming from there:

'/dev/vg-db-sda/set.1._usr' 
'/dev/vg-db-sda/set.1.root' 
'/dev/vg-db-sda/set.1._config' 
'/dev/vg-db-sda/set.1._var' 
'/dev/vg-db-sda/set.2.root' 
'/dev/vg-db-sda/set.2._usr' 
'/dev/vg-db-sda/set.2._config' 
'/dev/vg-db-sda/set.2._var' 
'/dev/vg-db-sda/set.3.root' 
'/dev/vg-db-sda/set.3._usr' 
'/dev/vg-db-sda/set.3._config' 
'/dev/vg-db-sda/set.3._var'

What do you suggest please?

Thanks again for your help.

Sylvain

Maybe I just found the explanation thanks to you Jim. You're right there are 3 installations installed respectively on HD1.1, HD1.2 and HD1.3 as boot locations. Can you confirm if this corresponds to /dev/vg-db-sda/set.1* , /dev/vg-db-sda/set.2* and /dev/vg-db-sda/set.3* ? If you do, I think we found the culprit ;-) Cheers. Sylvain
