Commands hang for file listings and bdf

Joe Profaizer — Fri, 15 Sep 2000 19:08:09 GMT

One of our DBAs is using the pfs_mount command for CDs and to dismount the cd-rom device he kills the pfs processes. After which, when anyone tries a "bdf" or "ll" or something similar, the command hangs and we receive the following output display..

NFS server rga6 not responding still trying

Please consult,

Yikes!!!! nexte time get them to pfs_umount rather than killing the processes. I have had this before and had to reboot... anybody?

Joe:

I think you're going to have to reboot! I had the same problem during my early explorations of pfs_mounts. Your processor usage is probably growing all the time and will continue to do so. Bite the bullet and boot. In the future, if you kill the daemons, do so in the reverse order that you start them. Then you should be OK.

And, as a second step take several moments to educate your DBA on NFS mounts. It is *not* good practice to kill NFS demons while a remote system is mounted.

Thanks, our DBA has now buried his head in the sand!

Joe:

Kofi's right. You should do pfs_umount first, then if that is successful, kill (sigterm (15)) the daemons in the reverse order you started them. Do not use kill -9 unless you absolutely have to -- here, in case the kill -15 didn't work.

Has any new resolutions (besides rebooting) come about in the last year? It has happened again - unfortunately.

When is HP going to do away with the pfs utilities? Just about every other UNIX platform has native support for mounting CD. When is HP going to get on the ball with this? PFS sucks, always did, always will.

That said, I thought I'd just mention that in our shop we avoid using PFS. For Oracle, we usually copy the contents of the Oracle install CDs into a staging area and NFS mount this area on the various machine when doing the install.

The install takes MUCH less time this way than by using pfs...and its much more stable.

PFS (and CDROM support in general) have not been the best. I would encourage customers with concerns about the state of CDROM support to contact your HP sales representative or the HP Response Center with your concerns.

Joe,

If you(or the dbas) need to install Oracle
on lot of systems, i would suggest you to
option of making a copy of the CD on
a NFS server and exporting it to other systems.
That makes the install process easier. You
wouldnt need to PFS mount the CDs on every
system where the install has to be done.

Regarding your problem, as everybody mentioned, reboot is the only way to get
out of it.
