I've got the following error, while trying to create many snapshots ( > 32 ) : "device-mapper: : Could not create kcopyd client". After some digging, I found out that the reason is resize_pool() in dm-io.c trying to do mempool_resize that is probably too large. I've seen that the issue has been raised in this list before at: https://www.redhat.com/archives/dm-devel/2005-April/msg00080.html, with the same conclusions, but there was no discussion and as far I can seen, the code has not changed since. I understand that the correct fix would be to use per-kclient pools. Is anyone planning to work/already working on this? Thanks, Igor
