[gpfsug-discuss] mmbackup ‐g GlobalWorkDirectory not being followed

How can I force secondary processes to use the folder instructed by the -g option?

I started a mmbackup with ‐g /gpfs/fs1/home/.mmbackupCfg1 and another with ‐g /gpfs/fs1/home/.mmbackupCfg2 (and another with ‐g /gpfs/fs1/home/.mmbackupCfg3 ...)

However I'm still seeing transient files being worked into a "/gpfs/fs1/home/.mmbackupCfg" folder (created by magic !!!). This absolutely can not happen, since it's mixing up workfiles from multiple mmbackup instances for different target TSM servers.

See below the "-f /gpfs/fs1/home/.mmbackupCfg/prepFiles" created by mmapplypolicy (forked by mmbackup):

DEBUGtsbackup33: /usr/lpp/mmfs/bin/mmapplypolicy "/gpfs/fs1/home" -g /gpfs/fs1/home/.mmbackupCfg2 -N tapenode3-ib -s /dev/shm -L 2 --qos maintenance -a 8  -P /var/mmfs/mmbackup/.mmbackupRules.fs1.home -I prepare -f /gpfs/fs1/home/.mmbackupCfg/prepFiles --irule0 --sort-buffer-size=5% --scope inodespace


Basically, I don't want a "/gpfs/fs1/home/.mmbackupCfg" folder to ever exist. Otherwise I'll be forced to serialize these backups, to avoid the different mmbackup instances tripping over each other. The serializing is very undesirable.

Thanks
Jaime
