Hello, when i create a preallocation vdi,during the creating,one node left and then create error! I do like this:(I use a server with 8disks) [root at sheepdog ~]# collie node list Idx - Host:Port Vnodes Zone --------------------------------------------- * 0 - 192.168.130.60:7000 64 1015195840 1 - 192.168.130.60:7001 64 1015195840 2 - 192.168.130.60:7002 64 1015195840 3 - 192.168.130.60:7003 64 1015195840 4 - 192.168.130.60:7004 64 1015195840 5 - 192.168.130.60:7005 64 1015195840 6 - 192.168.130.60:7006 64 1015195840 7 - 192.168.130.60:7007 64 1015195840 [root at sheepdog ~]# qemu-img create sheepdog:Alice -o preallocation=data 100G Formatting 'sheepdog:Alice', fmt=raw size=107374182400 preallocation='data' qemu-img: No object found qemu-img: sheepdog:Alice: error while creating raw: Operation not permitted when create error,check the node list as follows: [root at sheepdog ~]# collie node list Idx - Host:Port Vnodes Zone --------------------------------------------- * 1 - 192.168.130.60:7001 64 1015195840 2 - 192.168.130.60:7002 64 1015195840 3 - 192.168.130.60:7003 64 1015195840 4 - 192.168.130.60:7004 64 1015195840 5 - 192.168.130.60:7005 64 1015195840 6 - 192.168.130.60:7006 64 1015195840 7 - 192.168.130.60:7007 64 1015195840 I have tried this several times,always the master node left. and sheep.log as follows when fails: ........

If I create a preallocation vdi not that big(eg. 15G),i can create successfully, but the performance i test using iometer is very slow 4k %100read 100%sequence 2.897764M/s 4k %100write 100%sequence 0.089305M/s 1M %100read 100%sequence 29.83363M/s 1M %100write 100%sequence 10.05084M/s 4M %100read 100%sequence 50.71799M/s 4M %100write 100%sequence 9.699951M/s -------------- next part -------------- An HTML attachment was scrubbed...
