Perhaps I'm missing something, but if I try to use: qemu-img snapshot -c test someimg My image then goes into read-only mode. Is there a way to snapshot a running image without entering into this read-only mode? Current configuration: 3 sheepdog nodes running 0.6.0_71_g7ccce0d, 2 are running 1.4.0 (Debian 1.4.0+dfsg-1expubuntu4), one is running a self-compiled 1.5.1. I have two running instances on the nodes, one with qcow2 image, the other with a raw image in sheepdog. My interest lies in uptime for the webserver instances. I can cheerfully migrate the instance among the machines without issue, the next part would be being able to snapshot backup the instances without outage. /usr/sbin/sheep -c zookeeper:10.254.0.1:2181,10.254.0.2:2181,10.254.0.3:2181 -j dir=/var/lib/sheepjournal,size=1024 -w size=60000,dir=/var/lib/sheepcache -y 10.254.0.1 /var/lib/sheepdog /var/lib/sheepjournal is on a SSD OS boot drive. /var/lib/sheepcache is on an SSD partition. /var/lib/sheepdog is a 1 TB drive. Using zookeeper as nodes are in different buildings, and multicast is not enabled on our switches. -------------- next part -------------- A non-text attachment was scrubbed...
