Hi all, I have a 3 node testing cluster. On this cluster I'm simulating the configuration I have in production. In production cache is not enabled. I'm running a single guest where I've been writing lot's of data and now I was taking a snapshot (guest is running), but I get this error: root at test004:~# collie vdi snapshot -s lug12 backup_data Jul 12 12:21:32 [main] do_read(297) failed to read from socket: -1, Resource temporarily unavailable Jul 12 12:21:32 [main] exec_req(405) failed to read a response Failed to write object 80c8d12800000000 root at test004:~# collie vdi list Name Id Size Used Shared Creation time VDI id Copies Tag backup 0 10 GB 2.4 GB 0.0 MB 2013-07-10 16:58 19093f 2 backup_data 0 1.0 TB 501 GB 0.0 MB 2013-07-10 16:55 c8d128 2 sheep.log Jul 11 08:36:19 [main] md_add_disk(146) /mnt/sheep/dsk02, nr 1 Jul 11 08:36:19 [main] send_join_request(928) IPv4 ip:192.168.2.44 port:7000 Jul 11 08:36:19 [main] for_each_object_in_stale(388) /mnt/sheep/dsk02/.stale Jul 11 08:36:19 [main] main(780) sheepdog daemon (version 0.6.0_94_ge70a103) started Jul 12 12:21:32 [gway 27528] push_cache_object(516) failed to push object Object is read-only Jul 12 12:21:32 [main] modify_event(151) event info for fd 23 not found root at test004:~# ps aux | grep sheep root 2880 5.7 0.8 524916 16588 ?
