I need a little help concerning qvm-backup
…
A full backup has been taken to my NAS storage and been verified with qvm-backup-restore --verify-only
.
But this backup process has stored over 15GB on my local SSD as well, which lead to nearly full disk space. I had to abort backup operation to avoid more bad…
Is it normal that backup verification takes so much local disk space?
How can I free and clean up dom0 from the aborted backup data?
A reboot did not hide or clean up disk, warning still shows up and shows 98% usage.
[user@dom0 ~]$ sudo lvs
LV VG Pool Origin Data% Meta% Move Log Cpy%Sync Convert
pool00 qubes_dom0 97.42 79.57
EDIT:
Qubes OS 4.0
Thanks!

There is a similar issue , which suggests
sudo lvextend -l +100%FREE /dev/mapper/qubes_dom0-pool00
I invoked qvm-backup
+ qvm-backup-restore --verify-only
and did not alter logical volumes, so not sure about this.
Does Qubes by default create swap
logical volume as seen in the third terminal output or is this a consequence of not enough RAM during backup run?
How might I reclaim disk space, that was available before backup started?

Update 2:
There has been free space left on the disk, which I could assign to logical volume pool00
:
sudo lvextend -l +100%FREE /dev/mapper/qubes_dom0-pool00
The acute full disk warning now is solved.
Though I still have “lost” up to ~ 10GB of disk space due to aborted backup.
Is there any location for existent temporary files of qvm-backup
and qvm-backup-restore --verify-only
?
Or do you have any resources, which help me research further on this issue?
