Hi David:

Is this related to your FTP question or it to this?

https://forums13.itrc.hp.com/service/forums/questionanswer.do?threadId=1394912

Do you have a stale NFS mountpoint involved?

Where your (I hope not) running a 'pfs_mount'?

one of the most common culprits here is a nfs mounted filesystem that cannot be contacted (ie. the nfs server is down or ??)

take a look to see what's in the checklist / mnttab file and verfiy you've connectivity to each

this is a different issue altogether.... So I have make a new thread...

I too would suspect a stale NFS mount. Do you have another server that this machine mounts file systems from? You might be able to make that server available again, thus freeing up you bdf hang. Many times, however, the only answer is to reboot.

Hi David:

And what would you expect to see listed beyond?

Do you have a filesystem that is having I/O errors and thus is hung? What does this show?:

# cat /etc/mnttab

check below mount and nfs server

iuxbldi.ind.hp.com:/home/kumprash/vg_issue/trunk/ignite/src /pks

Re: bdf hangs

David Willams — Fri, 18 Dec 2009 16:13:27 GMT

"iuxbldi.ind.hp.com:/home/kumprash/vg_issue/trunk/ignite/src /pks
sh: iuxbldi.ind.hp.com:/home/kumprash/vg_issue/trunk/ignite/src: not found."

not sure what you thought typing that at the command line would accomplish?

it appears that the connectivity to
iuxbldi.ind.hp.com is either down,

or they've removed and / or unexported
"/home/kumprash/vg_issue/trunk/ignite/src"

or somethings blocking it

Hi David,

just go to /pks directory and see if it shows some contents in it using ls command. if it again hangs, then your nfs mount has a problem for sure.

try unmount that FS and then run bdf command. It should work.

You can also make a try by again mounting it and running bdf after that.

From 11i v2 onwards there is a -f switch to forcibly umounting NFS shares, it might work in some cases. If you have 11i v2 and no -f option then install the patch PHKL_31500 - which, in case also needs a reboot.

umount -f
