Red Hat Bugzilla – Bug 217703
clustered vg creation fails
Last modified: 2009-04-16 18:35:29 EDT
Description of problem: 5 node RHEL5 cluster, with all members joined, and clvmd running on each node, hooked via fiber to a winsys storage array with 2 tb of storage listed as sdb1. Note clvmd check below: [root@maggie ~]# service clvmd status clvmd (pid 2944) is running... active volumes: LogVol00 LogVol01 When sdb1 is used in a new VG, the following error message is returned: An error has occurred while commiting changes: clvmd (clustered LVM daemon) is not running on maggie.lab.boston.redhat.com. Start it and try it again. Version-Release number of selected component (if applicable): Latest conga How reproducible: I tried making the VG on a couple of different nodes in the cluster - all had clvmd running and were joined nodes, with the same result.
One other thing: it seems to me that 1) ricci should try and start clvmd for you. If it *is* trying to start it and failing, then the error message should say as much. 2) I wish there was a way to know if clvmd is running on a system when I go to that system page in the interface...I know this is not for now, but would be nice to have down the road.
So...this bug actually has two things that need to be corrected in order to close it: 1) The error msg above is returned if the locking_type does not equal '2' in the lvm.conf file....but clvmd WAS running...locking_type was just set to '1'. I think the error message needs to be modified to explain this better. 2) When installing lvm2-cluster rpms, the locking_type is no longer set to clustered...the default action is not to touch the value. the lvmconf tool must be run after installation with the arg --enable-cluster in order to set locking_type correctly...HOWEVER: The acceptable values for clustered locking type are now '2' and '3'...in fact, '3' is what maggie was set to after running lvmconf on it...so ricci needs to be modified such that this code: LVM::clustered_available() { return get_locking_type() == "2"; } allows for "2" or "3"
Devel ACK - Conga needs to be able to work with cluster volumes.
Changing to assigned as one more thing needs to be addressed: if "enable shared storage" checkbox is selected during cluster deployment, --enable-cluster should be run on every node (so user doesn't have to log into each machine and run it by hand)
Commited to -HEAD and -RHEL5
A package has been built which should help the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you.
