We've been testing FreeNAS and just began moving it into production doing backups. We use iSCSI to provide an off-site backup "drive" for our file-servers. For the last week, we've been setting up the FreeNAS end, then pointing each of the file-servers at their storage (only one file-server per target), and finally doing the backup, which is just a glorified rsync. The file-servers are Linux machines and we have been using open-iscsi on their end. The problem is that we seem to be able to lock-up FreeNAS's iSCSI service after around 100GB of transers on average. The last time this happened, we were able to write about 200GB over a 20Mb/s connection before it failed.
So we wondered if we would see the same problem when backing up from a file-server on the same network as the FreeNAS box (ie. over Gigabit). In that case, the iSCSI service locks up even faster, around 30-40MB.
I'm just curious if we are seeing something out of the ordinary, or if this is common-place. Has anyone else seen this?
Our problems are with a box running FreeNAS-8.2.0-BETA4-x64 (r11722).
