I have put

@reboot /usr/bin/lockf -k -t 0 /root/adm/.lockHM1 /sbin/hammer
mirror-stream /Backup1/Data /Backup2/Data &

@reboot /usr/bin/lockf -k -t 0 /root/adm/.lockHM2 /sbin/hammer
mirror-stream /Backup1/VersionControl /Backup2/VersionControl &

in cron.

and have

dfly-bkpsrv# cat /etc/rc.conf.local |grep local

and put the following in


#Kill all hammer mirror-stream processes.
pkill -f hammer mirror-stream /Backup1/Data /Backup2/Data
pkill -f hammer mirror-stream /Backup1/VersionControl /Backup2/VersionControl

#Sync Hammer Master pfs and Slave pfs
/usr/bin/lockf -k -t 0 /root/adm/.lockHM1 /sbin/hammer mirror-copy
/Backup1/Data /Backup2/Data && echo  "finished mirror-copy on `date`"
>> /var/log/HM1.log

/usr/bin/lockf -k -t 0 /root/adm/.lockHM2 /sbin/hammer mirror-stream
/Backup1/VersionControl /Backup2/VersionControl && echo  "finished
mirror-copy on `date`" >> /var/log/HM2.log

to make sure that the PFSes are in Sync before shutdown.

but the files HM1.log and HM2.log are not created in /var/log so I
dont know if this is working at all.

Well do I need this extra caution? Will the mirrors automatically sync
during a shutdown? Is there any way to force this?
