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
local_enable="YES"
and put the following in
/etc/rc.shutdown.local
#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?
Thanks
