Description das_deniz 1999-10-25 21:57:07 UTC

wierd - but has happend twice in a week - here goes:

do not have samba installed but am using smbfs
to mount a winNT HPFS volume. works fine until
it doesn't.

last time it failed the mount point would spit
up in the df output - it failed while mounted.

this time it failed while mounting so the df
output is clean but the directory listing for
the mount point is corrupted as before.

[root@ba /root]# cat /usr/local/bin/smbmount-maim
smbmount "//maim/ten" /maim -U guest

[root@ba /root]# smbmount-maim
Added interface ip=192.168.0.10 bcast=192.168.0.255
nmask=255.255.255.0
Password:
session setup failed: ERRDOS - ERRnoaccess (Access denied.)
smbmount: login failed
Could not umount /maim: Device or resource busy
smbmount: exit

[root@ba /root]# smbmount-maim
Added interface ip=192.168.0.10 bcast=192.168.0.255
nmask=255.255.255.0
Could not resolve mount point /maim

[root@ba /root]# ls /maim
ls: /maim: Input/output error

can't unload the smbfs module - reports busy - any cleanup
hints - other than rebooting - i can still mount the
NT volume to another mount point so don't have to reboot
yet - like i said weird.

Do a umount /maim.

If smbmount fails, it can leave a stale 'mount' on
the mount point.

Comment 2 das_deniz 1999-10-26 12:49:59 UTC

I swear i thought i tried that and it would tell me it's not in the
mtab -- maybe that was 6.0? or maybe this solution failed when it
was corrupted after the mount succedded?

anyway for this specific failure - smbmount fails and mount
point won't ls properly afterwards - this is the fix.

thank you (RedHat's BUGZILLA rules!)

Comment 3 Manuel S. 2004-07-01 19:23:20 UTC

I am getting this in fedora core 2. I mount a smbfs drive OR NFS 
drive and it will corrupt the mount point with an input/output 
error.. It also locks up the terminal session as well.. I get the 
same with mounting using smbmount... And umount'ing does nothing.. 
Any suggestions...
