pfs_mount and 10.20

[Christopher McCray_1]

I've heard about this and since pfs_mount didn't work, I'll ask the experts.

I have an Oracle 8.0.6 cd I need to mount, which didn't work. I started all the rpc processes and the two pfs processes. I had heard that pfs_mount will not work if root belongs to more than 8 groups. Is this correct? If so, is there a patch anyone knows about? And know, because management minds want to know, will removing root from a few groups to temporarily solve this limitatation cause any ill effects to my server? Thank you all in advance for your inputs.

Hi Chris:

Yes, in 10.20, if 'root' is a member of more than eight groups, pfs_mount will fail. The workaround is to remove the link /etc/logingroup.

I've run into this before, just kill all of the
"pfs" processes currently running, restart them
again using this:
/usr/sbin/pfs_mountd &
/usr/sbin/pfsd &
And then the ol'mount command itself (yours will vary)
/usr/sbin/pfs_mount /dev/dsk/c1t2d0 /cdrom

This leaves out the "nohup" that the Oracle doc's call for, but it works.

Thanks for the clarification and the info. We will try tomorrow because the boat anchor on which we're installing will take forever. What is the importance of this link? Will it cause problems if it is abscent too long? Thanks again.

Sorry Randy, but it didn't work for me. Thanks anyway.

I decided to test it before tomorrow, but it still didn't work. Is there anything else ou can think of that could be wrong? Here is my pfs_fstab file:

/dev/dsk/c0t1d0 /cdrom pfs-rrip xlat=unix 0 0

Here is the error I get:

pfs_mount: /dev/dsk/c0t1d0 on /cdrom: not rrip.
pfs_mount: giving up on /cdrom

Thanks again

Hi (again) Chris:

The error indicates that the CDROM is *not* a Rock Ridge format.

You could try:

# pfs_mount -t iso9660 -x unix /dev/cdrom /cdrom

BTW, if you aren't aware, killing the pfs daemons can lead to a hung system (with 'bdf' unresponsive as one symptom and continually increasing load averages as another). This state ultimately leads/requires a reboot.

An excellent document on pfs_mounts in general is Knowledge Base document #KBAN00000252 for 11.0 or #KBAN00000197 for 10.20.

Regards!

James,

The other command you gave me did't work, but the document you referenced solved my problem completely, even with root belonging to 12 groups. I wonder if it's because of the patch referenced in the doc? Anyway, thanks for the assistance. Good luck.
