Virtual box Version 7.0.8 r156879 (Qt5.15.2) on windows , i configured ubuntu as guest OS on windows VB , all working good , i was thinking that if i set virtual size to 25g it will be enough . But it keeps running out of space i don't understand why . for example when i do :
tmux
couldn't create directory /tmp/tmux-1000 (No space left on device)
This is what i see from my guest linux machine
df -H
Filesystem Size Used Avail Use% Mounted on
tmpfs 411M 1.3M 410M 1% /run
/dev/mapper/ubuntu--vg-ubuntu--lv 13G 12G 0 100% /

/dev/sda2 2.1G 154M 1.8G 8% /boot
tmpfs 411M 4.1k 411M 1% /run/user/1000
it is not 25g , also what is this /dev/mapper/ubuntu--vg-ubuntu--lv
