/root partition was 40 GB, about 15 GB was free
/swap 20 GB, unused
hibernate
restart failed
Using Gparted I found /root was full
resized /root to 50 GB
boots properly now
/var/log now contains 29.3 GB
/var/log/syslog 10.0 GB
/var/log/kern.log 10.0 GB
/var/log/syslog.1 4.1 GB
/var/log/kern.log.1 4.0 GB
I have no clue why this happened
how do I clean this up and prevent it from happening again?
PS: I rarely use Hibernate ... can't remember when I used it last,
if ever
