virtfs not getting disabled

[dev.null]

Yep, I've read the doc. (https://documentation.cpanel.net/pages/viewpage.action?pageId=1507360)

None of my accounts are jail enabled. (Home >> Account Functions >> Manage Shell Access)

According to the docs all I have to do is

umount /home/virtfs/<username>/usr/bin

It umounts just fine.

All the other mounted directories remain:

cat /proc/mounts | grep <username>
/dev/root /home/virtfs/<username>/bin ext3 ro,nosuid,noatime,errors=remount-ro,data=ordered,jqfmt=vfsv0,usrjquota=quota.user 0 0

/dev/root /home/virtfs/<username>/home/<username> ext3 rw,noatime,errors=remount-ro,data=ordered,jqfmt=vfsv0,usrjquota=quota.user 0 0

I can umount each one of those, but they all just end up coming back within a minute.

Any trick to really getting rid of virtfs?

Link works for me...



And yes, that's the documentation.

When I looked at the user's crontab I found it still referenced the jailed shell, I changed it to /bin/bash, unmounted the mount binds again, this time they didn't come back.
