Hi All, Testing sheepdog. create cluster for 3node with --copies=2 created vdi with 2 gb. start VM write date to vdi dd if=/dev/zero of=/dev/vda bs=1M count=2000 collie node info Id Size Used Use% 0 20 GB 740 MB 3% 1 20 GB 636 MB 3% 2 4.8 GB 632 MB 12% Total 44 GB 2.0 GB 4%, total virtual VDI Size 2.0 GB so far so good. now simulate node failure ( on node3 by killling sheep ) after recovery complited: collie node info Id Size Used Use% 0 20 GB 2.0 GB 10% 1 19 GB 1.9 GB 9% Total 39 GB 3.8 GB 9%, total virtual VDI Size 2.0 GB start sheep on 3 node again - wait for recovery, after finished: collie node info Id Size Used Use% 0 19 GB 1.4 GB 7% 1 19 GB 1.2 GB 6% 2 3.5 GB 1.2 GB 34% Total 41 GB 3.9 GB 9%, total virtual VDI Size 2.0 GB one more failure on the same node and bring it back again: collie node info Id Size Used Use% 0 18 GB 1.4 GB 7% 1 18 GB 1.2 GB 6% 2 2.3 GB 1.2 GB 53% Total 39 GB 3.9 GB 10%, total virtual VDI Size 2.0 GB now the node number 3 using 3x times more space than it should and node 1 and 2 2x times. Also seems that after failure it is trying ot copy all data over the other node. It could be a good idea just to copy changed data. ( like drbd ) Is it any way to keep data in sync and delete the old data? -- -- Michael -------------- next part -------------- An HTML attachment was scrubbed...
