Jonathan Earl Brassow 56fe3c6176 It's not enough to check for the kernel module in the case of cluster ... mirrors, we must also check that the log daemon (cmirrord) is running. The log module can be auto-loaded, but the daemon cannot be "auto-started". Failing to check for the daemon produces cryptic messages that customers have a hard time deciphering. (The system messages do report that the log daemon is not running, but people don't seem to find this message easily.) Here are examples of what is printed when the module is available, but the log daemon has not been started. [root@bp-01 LVM2]# lvcreate -m1 -l1 -n lv vg Shared cluster mirrors are not available. [root@bp-01 LVM2]# lvcreate -m1 -l1 -n lv vg -v Setting logging type to disk Finding volume group "vg" Archiving volume group "vg" metadata (seqno 3). Creating logical volume lv Executing: /sbin/modprobe dm-log-userspace Cluster mirror log daemon is not running Shared cluster mirrors are not available. Creating volume group backup "/etc/lvm/backup/vg" (seqno 4).		2010-07-21 13:40:21 +00:00
