When mirror has missing PVs and there are mirror images on those missing PVs, we delete the images and during this delete operation, we also reactivate the LV. But if we're trying to reactivate the LV in cluster which is not active and at the same time cmirrord is not running (which is OK since we may have created the mirror LV as inactive), we end up with: "Error locking on node <node_name>: Shared cluster mirrors are not available." That is because we're trying to activate the mirror LV without cmirrord. However, there's no need to do this reactivation if the mirror LV (and hence it's sub LVs) were not activated before. This issue caused failure in mirror-vgreduce-removemissing.sh test recently with this sequence (excerpt from the test script): prepare_lvs_ lvcreate -an -Zn -l2 --type mirror -m1 --nosync -n $lv1 $vg "$dev1" $dev2" "$dev3":$BLOCKS mimages_are_on_ $lv1 "$dev1" "$dev2" mirrorlog_is_on_ $lv1 "$dev3" aux disable_dev "$dev2" vgreduce --removemissing --force $vg The important thing about that test is that we're not running cmirrord, we're activating the mirror with "-an" so it's inactive and then vgreduce --removemissing tries to reactivate the mirror images as part of the _delete_lv function call inside and since cmirrord is not running, we end up with the "Shared cluster mirrors are not available." error. |
