iNode exhaustion with Overlay2 driver!


(Kidalex) #1

By checking df -i I noticed that one CentOS 7 system ran out of iNodes again.
for i in /var/lib/docker/*; do echo $i; find $i |wc -l; done revealed that 92% of all iNodes are used by overlay2.
What can I do about this situation? There is certainly not much running on this host.

I have the same problem with v18.09-ce on Debian “Stretch”.
