df(1) && vnconfig(8) hanging ....

2004-08-23 Thread Wilkinson, Alex
Hi all,

This morning I wanted to edit an ISO to instruct the kernel to redirect its
output to serial.

i.e 

# sudo vnconfig -v -c /dev/vn0 5.3-BETA1-i386-miniinst.iso
# sudo mount -t cd9660 -o rw /dev/vn0 /mnt
# sudo tcsh
# echo "/boot/loader -h" > boot.config
boot.config: Read-only file system.

Forget the afforementioned error. 

The problem that I have is now when I issue a df(1) my shell hangs: 

e.g.

# df -h
^C^C^D
^C^C^D

# ps -aux | grep df 
username   0.0  0.0   212   96  p2  D+9:04AM   0:00.00 df -h
username 3332  0.0  0.0   212   96  p1  D+9:04AM   0:00.00 df -h

# kill -9  3332

# ps -aux | grep df
username   0.0  0.0   212   96  p2  D+9:04AM   0:00.00 df -h
username 3332  0.0  0.0   212   96  p1  D+9:04AM   0:00.00 df -h

No change.

I'm not sure what has hung here, nor am I sure how to 'un-hang' my shell.

Any thoughts anyone ?

To follow-up again, why doesn't this work ?

# sudo umount -v -t nfs -f /cdrom/ports/distfiles

Just hangs.

Surely you can force an un-mount of an NFS filesystem ?

You can't write to a ISO9660 image [with the freebsd driver]

The only way you're going to be able to edit it is to copy it somewhere and 
edit that (alternatively you could merge in a new boot.config file using 
mkisofs)

Try ctrl-t

it gives you useful into about where things are bunged up.

Press ctrl-t or use the -l option to ps to find the wait channel (that will 
tell you where in the kernel it's blocked)

umount -f mountpoint

should be sufficient.

I think it depends how you mount it as to how long the kernel will wait before 
unmounting it.
