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?
