This is on the latest build as well. 

[root@hayes-02 ~]# service cmirror start

Comment 2 Jonathan Earl Brassow 2008-01-24 17:33:40 UTC

I've seen this too.  I think this is because I'm not properly exiting the AIS
ckpt service.  It should be in the latest build now though.

Either way, if the log server dies or gets killed by -9, we should be able to
restart... and AIS should cleanup.

What you've done above is the same as doing:
1) clogd
2) killall clogd
3) clogd

If this now works, then try:
1) clogd
2) killall -9 clogd
3) clogd

Comment 5 Corey Marthaler 2008-02-04 14:56:18 UTC

This issue is marked ON_QA but isn't fixed in the latest build. Should the fix
be in the following?

cmirror-1.1.8-1.el5
kmod-cmirror-0.1.5-2.el5
lvm2-2.02.32-1.el5
lvm2-cluster-2.02.32-1.el5

Comment 6 Jonathan Earl Brassow 2008-02-04 17:14:59 UTC

my guess is that this is an OpenAIS issue and won't be fixed by any of the above
packages....

Steve,
I have a cluster you can use to test this.

Comment 7 Steven Dake 2008-02-04 17:24:11 UTC

sigh I believed whoever changed it to modified had fixed the problem. 
Apparently not.

I'll talk to you Jon and reassign this bug from you to me.

Comment 8 Corey Marthaler 2008-02-26 20:10:18 UTC

Fix verified in openais-0.80.3-12.el5.
