[Systems] Disk space running out on freedom.sugarlabs.org

[Bernie Innocenti]

Hello,

once again we're running low on disk space, so I'd like to see what we
can recover. Here is a list of all logical volumes:

  LV                   VG          Attr      LSize
  backup               freedom-lvm -wi-ao--- 1000.00g
  freedom-virtual      freedom-lvm -wi-ao---  500.00g
  hammock-data         freedom-lvm -wi-ao---  150.00g
  ole-data             freedom-lvm -wi-a--- - 100.00g
  hanginggarden-data   freedom-lvm -wi-ao---   50.00g
  docker_extra_storage freedom-lvm -wi-ao---   15.00g
  socialhelp           freedom-lvm -wi-ao---   20.00g
  hammock              ole         -wi-ao---    2.73t

The "ole" volume group lives on separate disks which presumably dogi
bought and installed on freedom a while ago. Dogi, could you confirm?

On the freedom-lvm VG, the largest partition is /backup, which is 70%
full. I'm afraid I've already done all I could to shrink it with the
wizbackup changes of a few months ago, and we need the extra buffer
space to account for growth.

Next by size is freedom-virtual, which contains a plethora of VMs owned
by Dogi, plus a lot of old images which we're no longer running:

 -     template-wheezy                shut off

Dogi, could you please list all the images you're still actively using?


The next largest LV is hammock-data. Since the hammock Vm already has an
antire array of 2.7TB, perhaps it could move its data out of
hammock-data and free up the space?

Same goes for ole-data, mounted by openbell and hanginggarden: do these
belong to OLE, Dogi? Can we move them to the OLE VG?


For completeness, here is the df:
