[gpfsug-discuss] unlocking mmafmctl prefetch

[Uwe Falke]

Dear all,

we had to kill a running mmafmctl <fs> prefetch ... including the 
children on another node.

The processes appear all gone

# mmdsh -N ALL 'ps -aef | egrep -i "(afm|prefetch)" | grep -v grep | wc 
-l' | sed -e 's/^[^:]*:/xxx:/'
xxx:  0

But trying to start another prefetch tells me it is locked (Cannot 
initiate prefetch for fileset root.  Recovery or another instance of 
prefetch may be in progress.).

Any suggestion how to remove that?

I had recycled mmfsd on the node i run the command and I moved the SG 
Mgr for the SG in question, had not helped.


Thanks in advance

Uwe
