hello, I have running a cluster with 3 nodes. and I store more than 3TB data in my cluster,
there are 50 VMs running on the cluster.
but one node have crash yestoday, when I restart the crashed sheep, my cluster going to recovery, then, many VMs are very slow, I check the disk idle time of the vm, it often shows 0, I think many IO are block when recovery.  then I check the disk, iostat and the bandwidth of all sheep nodes, there are all normal .   I think the nodes hardware are very well,the reason of vms slow is caused by sheepdog , how to solve this issue? ------------------ 原始邮件 ------------------

hello, I have a question for clone a sheepdong image.
my clone steps are:
1. I create a image named myimg
2. I write some files to  myimg
3. I create a snapshot named 'newest', dog vdi snapshot -s newest myimg
4. I ran 'dog vdi clone -s newest myimg myimg2'
5. I ran 'dog vdi delete myimg'
6. I attach the myimg2 to QEMU, but I can't found the files I wrote at step 2.

what happen ? if I delete the source image 'myimg', it will be make data lost ?
