pfs_mount

sheevm — Thu, 09 May 2002 18:38:53 GMT

I pfs_mount the CD and I logged out of that session. I cannot BDF or cd /cdrom. The mount point is not working. This is the second time this is happening. If I leave that session on until I unmount that everything is fine.

Only way out is to reboot the server. Any one has any idea resolving this without rebooting?

Thanks

Hi Raji,

use folloing way then even if you logout of session it will still stays on.

#/usr/sbin/pfs_mountd &
#/usr/sbin/pfsd 1 &
#pfs_mount -x unix /dev/dsk/????? /cdrom

then at anytime you can run
#pfs_umount /cdrom

Hello,

See if your statd and lockd daemons are running, and start them if they aren't. That is about the only trick I know to escape the pfs hung problem without rebooting.

Speaking of pfs, I'd sure love to see that wonderful piece of software on a product roadmap that ends up in the trashcan!

Sachin:

I exactly did what you say. But if I logout of the session my pfs processes are gone.

It issuppose to run in the background but it does not. Is there any patch? Anyone know.

At this point nothing is working.

Hi Raji

the process is as :

pfs_mountd &
pfsd &
pfs_mount /dev/dsk/cxtydz /cdrom

now there are 4 process which will run in background the mount and pfsd and the rpc 's , to fully stop it you will have to kill those and that sjould be done with the least one first otherwise the system will hand on bdf display etc

Hi Raji,

Try preceeding the pfs commands with nohup.

EX:
#nohup /usr/sbin/pfs_mountd &
#nohup /usr/sbin/pfsd 1 &
#nohup pfs_mount -x unix /dev/dsk/????? /cdrom

This forces them to ignore hangups.

Thanks for your response. Nothing worked I have scheduled a reboot.

We need to use /dev/rdsk with pfs_mount I understand not /dev/dsk. If I am wrong correct me.

Thanks

Raji,

You're correct /dev/rdsk/cxtydz must be used.
Sorry I didn't notice that earlier.

Rgds,
Jeff

Hi Raji:

pfs uses raw devices and thereby you can use the 'rdsk' when mounting.

Also regarding patch, apply these if you have not yet:

HP-UX 11.00 - PHCO_16438 (s700_800 11.00 PFS cumulative patch)

hi,

use nohup along with the commands. one more thing i suggest is if ur machine is not an nfs server, stop nfs processes. if it is an nfs server mount CD on some other machine and nfs mount the CD on local server.

/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.client stop

Hi Raji,

You ran the pfs daemons and logged out, that was a problem. If you want to do that, run the pfs daemons with a nohup, this will not kill the daemons if you logout.

#nohup /usr/sbin/pfs_mountd &
#nohup /usr/sbin/pfsd &
#pfs_mount -o xlat=unix /dev/rdsk/????? /cdrom

then at anytime you can run
#pfs_umount /cdrom

Hope this helps.
