I have put into attachment the one reasonably easy. It is about mounting
ext3 partition into mysql dir and then running mysql.
Problem here is, that doing so is not enough. I spotted, that is is
needed
to manually restart mysql when that ext3 partition is mounted (and chmod
needs to run before it as well, otherwise mysql has not write permission
there and crashes). Only after that resource starts and works properly.
So far, I have created:
class MYSQL(CIB10):
def add_resources(self):
self._create('''primitive fs1 ocf:heartbeat:Filesystem op monitor
interval="20" timeout="40" start-delay="10" params device="%s"
directory="%s" fstype="%s"''')
you're using "...=%s", but then not passing in any value. thats not
going to work.
think of it like a printf
I understand it. But this is just class declaration. So it would be called
elsewhere.
Not really. This is creating resources in the cib - the definitions
need to be complete.
Ah.
Got it.
class OCFS2(CIB10):
def add_resources(self):
self._create('''primitive clvm ocf:lvm2:clvmd op start
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
self._create('''primitive cmirror ocf:lvm2:cmirrord op start
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
self._create('''primitive dlm ocf:pacemaker:controld op start
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
self._create('''primitive o2cb ocf:ocfs2:o2cb op start
interval="0" timeout="90s" op stop interval="0" timeout="100s"''')
self._create('''primitive ocfs2 ocf:heartbeat:Filesystem params
directory="%s" fstype="ocfs2" device="%s" op monitor interval="20"
timeout="40" op start interval="0" timeout="60s" op stop interval="0"
timeout="60s"''' % ("mount-dir", "ocfs2-disk"))
self._create('''group o2stage dlm clvm o2cb cmirror''')
self._create('''clone c-o2stage o2stage meta interleave="true"''')
self._create('''clone c-ocfs2 ocfs2 meta interleave="true"
ordered="true"''')
self._create('''colocation colo-ocfs2-o2stage inf: c-ocfs2
c-o2stage''')
self._create('''order order-ocfs2-o2stage 0: c-o2stage c-ocfs2''')

def add_resources(self):
self._create('''primitive fs1 ocf:heartbeat:Filesystem op
