Let's stick to written communication for sysadmin stuff, so everyone in
SL stays informed.

We need to restore ASLO as soon as possible, we can't wait that long.

The extra headroom in /backup is needed to make sure backups never run
out of space and fail.

We need to shrink some LVs to make room for ASLO and all the activities.
Freeing up 30-40GB might suffice, but it would be best to have extra
free space for future growth.

So let's move (or delete) all those inactive qcow images somewhere else.
Long-term you should arrange to move everything to another server owned
by OLE, so SL won't have to squeeze in the remaining space. This
temporary situation has been going on for years now.

Actually, please *do* rush and free up all the space you can now. We
don't want to host production VMs as qcow files inside existing
partitions, because it's slow and fragile.

I moved those to /backup.

I'm not sure either. Looks like parts of somosazucar.org? Icarito, do
you use this VM?
