Stuck in a loop of freeing up space and filling it up again when rebuilding

Ah, I see. I don’t think that was mentioned anywhere. I’ll check tomorrow where that information might be usefully added.

However, the situation seems to look much brighter now:

$ df -h
Filesystem              Size  Used Avail Use% Mounted on
udev                    476M     0  476M   0% /dev
tmpfs                   100M   12M   88M  12% /run
/dev/mapper/vg-lv_root   19G  8.4G  9.0G  49% /
tmpfs                   497M  1.4M  495M   1% /dev/shm
tmpfs                   5.0M     0  5.0M   0% /run/lock
tmpfs                   497M     0  497M   0% /sys/fs/cgroup
/dev/sda1               461M  160M  278M  37% /boot
tmpfs                   100M     0  100M   0% /run/user/1000

Not sure where all the space came from but it looks good, doesn’t it? Do you still think I need to upgrade the server?
