Hello, We are encountering a backup problem using tgtd. Though, we believe it to be a kernel problem, you might have encountered such an issue before and have some lights about it. We backup a Linux RHEL 6 system using an iSCSI link connected to an usb3 drive on another system. The problem is that the backup process on the source system is writing too fast for the network to send data. The number of dirty pages of unwritten data keep rising on the source system because of the network bottleneck.This keep growing until the source system freeze because of too much allocated memory. We believe it’s a kernel issue which has not been fixed even in the most recent kernel versions (3.3). To fix that, it would require a max dirty pages per device kernel parameter which is not available at this moment. Have you heard of any « strategy » which we could use as a workaround for this specific problem ?
