Fuse based filesystem won't unmount on NFSv4 with Kerberos
Last modified: 2010-12-03 19:09:53 EST
Description of problem:
Unmounting a fuse fileystem on a NFSv4 with kerberos fails.
As a the user, fusermount -u gives error:
umount: /home/[user]/mnt/winlnx_wwwroot: block devices not permitted on fs
As root, it gives:
fusermount: bad mount point /home/[user]/mnt/winlnx_wwwroot: Permission denied
The errormessage as root is correct behavior, as local root do not have access the exported filesystem.
Version-Release number of selected component (if applicable):
fusermount version: 2.8.1
Steps to Reproduce:
1. Mount a fuse filesystem on a NFSv4
2. Unmount the filesystem using fusermount -u
No unmount posible
fuse drive unmounted
* This action works fine with NFSv3 (with the same user and computer)
* This acrion works fine on local filesystem (eg. in /tmp/)
All servers RHEL/CentOs 5.4
[server]:/home/[user] on /home/[user] type nfs4 (rw,sec=krb5,sloppy,addr=10.x.x.x,clientaddr=10.x.x.x)

Strace of the bug in question
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
