Hello golly,
Thanks for your return, actually I tried to done a fail-over VE (LAMP).
I've two RHEL 5.5 servers (HN)with openvz (ovzkernel-2.6.18-238.9.1.el5.028stab089.1.x86_64.rpm)
I've follow this howto HAclusterwithDRBDandHeartbeat on the wiki with drbd 8.3.10,pacemaker-1.0.11 and heartbeat-3.0.3, corosync 1.2.7 (not running).
"HA" configuration seems OK
I've a VE11 with LAMP (Apache + php + mysql)
Actually, I've done two drbd "FS" /VE11 and /data, on /VE11 there are OS + binary for (apache, php, mysql ...) on /data there are data for apache and mysql database.
In fact I've done a FS mount point /data on the VE11 so /data is a FS for the VE11
My question is how the "primary" VE11 must to migrate on the secondary HN2 when the first HN1 failed ?
Must I need to use drbd only for /data and need to setup an other VE on the secondary HN2 it use only data ? Or must must I need to used drbd for /VE11 and /data ? I wanted to done a fail-over configuration.
so
HN1
VE11 with @IP1
/VE11 and /data with drbd
HN2
VE11 with @IP1
/VE11 and /data with drbd
or
HN1
VE11 with @IP1
only /data with drbd
HN2
VE21 with @IP2
only /data with drbd
thanks for your answer
