rmdir: Cannot remove mountable directory

Robert Bissett — Tue, 16 Sep 2003 16:37:05 GMT

Hi,
on a HPUX 11i server running vpars, I'm trying to remove an directory using rmdir but get the following reply :
rmdir /bkp
rmdir: /bkp: Cannot remove mountable directory
So I do the following:
umount /bkp
umount: cannot find /bkp in /etc/mnttab
cannot unmount /bkp

I try mount it:
mount /bkp
mount: /bkp was either ignored or not found in /etc/fstab
It's not listed in SAM under LVs or Filesystems. It's not mentioned in /etc/mnttab or /etc/fstab. Also, there are no device files for it in either /dev/vg00 or /dev/vg01 - the 2 volume groups I have.

Perhaps another file is linked to it ?
The output of ls -ail is as follows :
2 drwxr-xr-x 2 root root 4096 Sep 16 17:45 bkp

I'm stumped - any ideas ?

Not very positive on what can be the cause

but did u check if automounter/autofs has been configured to mount on this dir..

Hi Robert,

Try this -

mv /etc/mnttab /etc/mnttab.old

mount -a

umount /bkp

-Sri

I just reproduced the error in one of my test machines. The prob is that automounter has been configured to mount to the directory.

# ps -ef | grep auto

# kill

# vi /etc/auto_master
remove the ref

# /usr/lib/netsvc/fs/automount/automount -f /etc/auto_master

# rmdir /bkp

Is it HP-UX 11.X ?. If you are using autofs then u dont have to kill the process. Autofs can read the configuration file on the fly.

Hi,
thanks for your replies, however problem still exists. It's not the automounter.....

ps -ef | grep auto
root 5396 5326 0 07:04:05 pts/ta 0:00 grep auto

Also, renaming /etc/mnttab didnt work.....

$ mv /etc/mnttab /etc/mnttab.old
$ ls /etc/mnt*
/etc/mnttab.old
mount -a
$ umount /bkp
umount: cannot find /bkp in /etc/mnttab
cannot unmount /bkp
$ rmdir /bkp
rmdir: /bkp: Cannot remove mountable directory

Any other ideas ?

Hi,

just a stupid question: do you have any other mount points that use /bkp ?

I can reproduce the problem by doing this.

# mkdir /delete
# cd /delete
# rmdir /delete
rmdir: /delete: Cannot remove mountable directory

You don't happen to be in the directory you are trying to delete do you?

I got this off the linux kernel mailing list and is a quite from Andrea Arcangeli

"If the directory is the root directory or the current working directory
of any process, it is unspecified whether the function succeeds, or
whether it fails and sets errno to [EBUSY]."

Looks like it could be a bug/feature in HPUX too

Hi,
I tried ls -ali initially. Here is a portion of the output (with dates and times removed for ease of viewing)....showing all directories with the same inode number i.e. 2, as is normal I think.

Also, I'm not in the directory while trying to remove.

Do that inside the /bkp dir?

Hi,

Does "fuser" show anything?
Try:
#fuser -c /bkp
and
#fuser -f /bkp

Kind regards,
Zigor

Hi,

Look also at "/etc/exports".

Hope this helps.
Kind regards,
Zigor

Re: rmdir: Cannot remove mountable directory

Robert Bissett — Wed, 17 Sep 2003 12:34:24 GMT

Hi,
no, nothing in /etc/exports and fuser shows nothing using the dir.

Hi,
in case I didnt mention the /bkp directory is empty.

john korterman — Wed, 17 Sep 2003 12:50:59 GMT

Hi,

Does this show nothing:
# ls /bkp | cat -v

what does
# file /bkp
show?

regards,
John K.

Re: rmdir: Cannot remove mountable directory

Robert Bissett — Wed, 17 Sep 2003 12:55:04 GMT

Results...

$ ls /bkp | cat -v
$ file /bkp
/bkp: directory

i.e. empty directory.

Zigor Buruaga — Wed, 17 Sep 2003 13:04:21 GMT

Hi,

My stupid suggestion, let's try with other commands to see if the result is the same:

Try to move with "mv /bkp /bkp.old"
and if it works, try again to delete "/bkp.old"
What happens?

Kind regards,
Zigor
