Hi Hu,
Since Sheepdog has a mechanism that does not place objects in the same zone_id.
Can you try to change ZONE id in each node.
Id Host:Port V-Nodes Zone
0 130.1.0.147:7000 128 0
1 130.1.0.148:7000 128 0
2 130.1.0.149:7000 128 0
Best Regards, Saeki.

Hi Hitoshi,
Sorry for disturb.
I'm testing redundancy policy of sheepdog via iSCSI. I think
if I create a 1G v-disk, the total space cost of this device
should be 3*1G under a 3 copies policy. But after tests, I
find the cost of this device is only 1G. Seems no additional
copy is created.
I don't know what happened. I'd like to should my configurations
and wish you could take some time to help me. Many thanks!

Hmm, seems strange. For diagnosing, I have some questions:
1. Can you see any error messages in log files of sheep?
2. Could you provide lists of obj/ directories of sheep servers?
3. Is this reproducible even you make file system on the iSCSI target
and put data on the file system?
4. Is this reproducible even you append oflag=sync to the option of dd?
Additionaly, could you provide options of sheep?
Thanks,
Hitoshi
