And it's also better to run 2 sheep daemon instead of use a raid0 because if one of the disks dies, I lose only the chunks on that disks and not both like it would happen on raid0. So less time needed to sync the lost chunks. > I think it is a good idea to support specifying interfaces used for > normal I/Os and object recovery. For example: > $ sheep /store_1 --nic io:eth0 --nic sync:eth1 > $ sheep /store_2 --nic io:eth2 --nic sync:eth3 I do not have clear what you mean with normal I/0. |
