The 'lvconvert' command refuses to deal with this sub-LV outright - it expects to be given the name of the top-level LV. So, just like we do with mirrored logs, we strip-off the portion of the name that is not the top-level LV and issue the command on the top-level LV instead. --- WHATS_NEW | 1 + daemons/dmeventd/plugins/lvm2/dmeventd_lvm.c | 4 ++-- 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/WHATS_NEW b/WHATS_NEW index f0a764b..5eb4abe 100644 --- a/WHATS_NEW +++ b/WHATS_NEW @@ -1,5 +1,6 @@ Version 2.02.104 - =================================== + Handle failures in temporary mirror used when adding images to mirrors.
