I've tried to uninstall docker and failed because I am not able to remove this dir /var/lib/docker
and it gives me this error:
(base) [xxx@xxx ~]$ sudo rm -rf /var/lib/docker/
rm: cannot remove ‘/var/lib/docker/containers/ca556f26e3680b5826300d72f83bfb507d4b0bfc399f22358baa46721e4c9366/shm’: Device or resource busy
rm: cannot remove ‘/var/lib/docker/overlay2/8d3fdb603781fc29fd02c49be5cf67be49b578a3bc92cc010ab308a037499e8b/merged’: Device or resource busy
I followed this answer because it had a very similar issue to mine. But if I check with lsof
or fuser
commands I get no output:
(base) [xxx@xxx ~]$ sudo lsof +D /var/lib/docker/
(base) [xxx@xxx ~]$ sudo /sbin/fuser /var/lib/docker/
Mount doesn't work as well:
(base) [xxx@xxx ~]$ sudo umount /var/lib/docker/containers/ca556f26e3680b5826300d72f83bfb507d4b0bfc399f22358baa46721e4c9366/shm
umount: /var/lib/docker/containers/ca556f26e3680b5826300d72f83bfb507d4b0bfc399f22358baa46721e4c9366/shm: not mounted
However, if I check with option `-m' to find resources utilized with this filesystem I get a dozen processes listed:
(base) [xxx@xxx ~]$ sudo /sbin/fuser -m /var/lib/docker/

That represents most of the processes on the server, and I am not sure how they are all assigned to docker lib dir? It must be some kind of confusion, at least for me.
Hopefully, someone can help me to resolve this issue! Thanks a lot.
EDIT: I deleted docker prior to this step following instructions from here: uninstall docker
