ncpfs exported via NFS mystery

ncpfs exported via NFS mystery

Post by Bryon G. Ri » Tue, 06 Aug 1996 04:00:00



Has anyone else come across this?

I am running Linux 2.0 and ncpfs 2.0.4 on a 386DX25.  I have mounted my
Netware volumes as /netware/ntc.  I am running my NFS deamons (mountd and
nfsd) with the -r option.  /netware/ntc is in the exports file.

On Linux, everything looks good.

I mount the filesystem on my HP-UX 10 machine and on the surface everything
looks good.  Lets say I have 26 files in a directory, a through z.  If I open
the file g, the data looks good.  If I open the file d, I get the contents of
file g.  If I open file s, everything looks good.  This seems to me to be
a problem with ncpfs and NFS on the Linux platform.  Has anyone seen this
behavior?  Is there a fix?

Thanks in advance,

Bryon

1. Can't unmount volume which was once exported via NFS

Hi!

Starting with 2.5.72-bk, I've been hit again by the old "umount:
/volume: device is busy" bug when trying to unmount an ext3 volume which
once was being exported via NFS.

To reproduce the problem, I compiled 2.5.72-bk3 with the configuration
file attached an plugged it on a RHL9 box. To reproduce the bug, I
exported my "/data" volume:

[snip from /etc/fstab]
/dev/hda3        /data           ext3    defaults,noatime        1 2

as follows:

[snip from /etc/exports]
/data           192.168.0.100(rw,no_root_squash) 192.168.0.0/24(ro)
/data/CD        192.168.0.3(rw,no_root_squash)

Then:

# mount
...
/dev/hda3 on /data type ext3 (rw,noatime)
...
# /etc/init.d/nfs start
...
# /etc/init.d/nfs stop
Shutting down NFS mountd
Shutting down NFS daemon
nfsd: last server has exited
nfsd: unexporting all filesystems
# umount /data
umount: /data: device is busy
# lslk
SRC        PID DEV    INUM SZ TY M ST WH END LEN NAME
(unknown) 2235 3,2 1004050     w 0  0  0   0   0 / (rootfs)
atd       2279 3,2 1005324  5  w 0  0  0   0   0 /var/run/atd.pid
# lsof|grep data
<Nothing>
# dmesg
<Nothing interesting here, I think>

Any ideas what's going on here? This old bug friend of mine disappeared
at 2.5.69 (if my memory serves me well), but something has caused it to
appear again.

Thanks!
