Description Flags
Patch - fix empty mounts list return from unlink_mount_tree() none

Description Ling Li 2021-06-08 01:39:55 UTC 
Description of problem:
After upgrading from CentOS 8.3 to 8.4, autofs fails on NFS /home mounting, complaining:

Jun 08 01:32:16 cent8 automount[1502]: do_mount_autofs_indirect: already mounted as other than autofs or failed to unlink entry in tree
Jun 08 01:32:16 cent8 automount[1502]: handle_mounts: mount of /home failed!
Jun 08 01:32:16 cent8 automount[1502]: master_do_mount: failed to startup mount

If downgrade the autofs package only, to 5.1.4-43, solves the problem.


Version-Release number of selected component (if applicable):

autofs-5.1.4-48.el8.x86_64


How reproducible:

A clean install, set up sssd/ldap, start autofs.


Additional info:

If, I manually mount a subdirectory of /home, say 

  mkdir /home/myself
  mount -t nfs nfs_server:/zones/home/myself /home/myself
  systemctl restart autofs

it magically stops complaining (for this time), and automount works on other subdirectories under /home.

It seems there's a missing patch, I was so sure I had fixed that in RHEL
but clearly not.

Created attachment 1789305 [details]
Patch - fix empty mounts list return from unlink_mount_tree()

fyi - upstream patch is.

Just to be sure, could you try this build and ensure the problem
is resolved please:

Comment 4 Ling Li 2021-06-08 15:28:50 UTC 
Yes, that solved the issue.  Tried on two different installs (one container and one actual box).  Thank you!
