Hello everyone.
I ran into problem.
I cannot format ocfs2 partition with pcmk until "primitive o2cb
ocf:ocfs2:o2cb" is running. Right?
Probably
I have tested mkfs.ocfs2 as Tim suggested and it works. So whole cluster
configuration could be done by cts now and only mkfs would be ran by script.
Now I'm quite unsure. I could prepare ocfs2 partition with pcmk and just
reuse it, but maybe you will come up with better idea.
I added script I use for adding ocfs2 resource (cluster is expected to be
running and have some stonith ready) to attachment. It works fine so far.
Frankly, I'm quite clueless how to get this into CTS as I'm not much into
Python. Maybe if somebody could help me how to get some easier scenario into
CTS, I'd be able to figure out other scenarios as well.
The script is fine up to the point where you add ocf:heartbeat:Filesystem.
It can stop after you do the mkfs.
Copy the HASI class (which already has the logic for adding the dlm
and o2cb resources) in CIB.py and add the Filesystem resource line to
the end of add_resources().
You'll probably need to add the cmirror and clvm parts there too.
This is class for full OCFS2 configuretion (except STONITH):
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"''')
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''')
I put in also interval so there are no issues with them.
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.
self._create('''property no-quorum-policy="ignore" op monitor
interval="10" timeout="120" start-delay="10 params binary="%s" pid="%s''')
self._create('''primitive sql1 ocf:heartbeat:mysql''')
self._create('''colocation col-sql1 +inf: sql1 fs1''')
self._create('''order order-sql1 +inf: fs1 sql1''')
Where are your ocfs2 resources?
This is different task. It is about ext3 fs being mounted into dir
/var/lib/mysql (I didn't specify it in case other distros have it
elsewhere) and then mysql being ran.
Class with OCFS2 is mentioned above.
Thanks all for help.
