pfs_mount and system problems

[Chris Fadrowski]

I tried to pfs_mount a cdrom this morning however, it didn't work so i went thru the commands;

nohup /usr/sbin/pfs_mountd &
nohup /usr/sbin/pfsd &

and still couldn't do anything with the CDROM. However, now i can't run BDF or ioscan. systems says NFS server is not responding. I know pfs uses nfs however we don't run it on our systems. is there any way out of this with out rebooting the server?

Hi Chris

Unfortunatley no , this would need only a system reboot , though this will only be problem in bdf and ls where in it checks for the disk .

In case you end up messing the pfs_mount the better way out is to ps -aef | grep pfs and kill the process with their ids starting from the least to the highest value.

I have not being able to find a workaround on this issue except a reboot.

Hi Chris:

Well, don't waste any more time; reboot. The escalating CPU usage, the slow 'bdf' and 'ls' output are all symptomatic of a 'pfs_mount' gone wrong. If you kill the daemons in the wrong order (i.e. not the opposite) of the way they were started, you end up in this situation.

I suggest you be on the lookout for a long-overdue mechanism which obviates pfs_mounts. It's available now in 11.11 and should be next month (June) in 11.0. In 11.11 the enabling patches are:

PHCO_25841
PHKL_26269
PHKL_25760

Hi Chris,

pfs is notorious for this type of situations. You have to reboot the system to get out of this.

Hope this helps.
