Deactivating and then reactivating the volume group got the mirror to finally sync properly. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. If you can recreate this, it will show more info when attempting to send the request to the cluster.... would be nice to have. I haven't been able to reproduce this lately, marking verified. cmirror-1.1.15-1.el5 kmod-cmirror-0.1.8-1.el5 Assuming this VERIFIED fix got released. Closing. Reopen if it's not yet resolved. |
Description of problem: I created a cmirror from all 4 nodes in the cluster at the same time. One of the nodes got stuck while attempting to sync.
