Oct 17 14:01:36 grant-01 lvm[2579]: Monitoring mirror device SPLIT-2log for events. Looks like this is a regression of the fix in comment #15 of bug 612221. [root@hayes-02 ~]# lvcreate -m 1 --mirrorlog mirrored -L 100M -n mirror centipede Log type, "mirrored", is unavailable to cluster mirrors Git commit ID 0864378250956c310cb81608978d091fcdcc97d8 was meant to disallow 'mirrored' logs for cluster mirrors. However, when add_mirror_log is used to create the log (as is now the case when using 'lvcreate' or converting only the log) the check is bypassed.
