Hello,

the VM 105 is a linux server.

Here is the configuration :






Can you help me to reduce this ? I want to reduce vda2 where there is vg-home

Hi,

like I said, use gparted live-cd. Play with it using a test VM(with a smaller vdisk but with the same kind of lvm/partition like the real one). Then when you figured how to do, then you can do the same on the real VM. By the way, create always a backup before doing this!

Good luck!

If you want to use replication, you should check "Thin provision" in the storage creation menu. Otherwise, when you create a zfs snapshot, it will take up as much space as the source. In your case, you need to create a backup of virtual machines to external storage, then select "Thin provision" and import the virtual machines back. Read about the creation of a sparse file systems zfs. Meybe direct setting of file system properties via the command "zfs set reservation=none <zfsname>"may help. In my case, backup and reverse import solved the problem.
