I've got an issue at the moment where backup jobs are taking a longt time to begin processing - they get to the "Hard disk 1 (0.0 B) 0.0 B read at 0 KB/s [CBT]" and hang there for a long time before actually starting. I've had some jobs take 15 minutes to start wheras one job has took 40 minutes before starting. This is me running one or two jobs at a time, which the server has had no issue with in the past. Also 'Bottleneck' stays on "Detecting" until the job actually starts processing correctly.
It's not CBT related as i've tried disabling that on a job, but it made no difference. I've restarted the server, with no luck, and recreated a job from scratch again with no luck. Once the job begins, it correctly uses [san] and is a fast 400MB/s+ speed so the job completes quickly. I've also rescanned the backup infrastructure again with no issues.
After completing, the load is "Sourece 99% > Proxy 23% > Network 22% > Target 1%". This used to work without issue, and is a new HPDL380 G9 server comprising of 18x 1.2TB 10K disks in a RAID10 configuration. The server is not being overworked at all (1% CPU, and 12% memory)
Any ideas would be greatly appreciated.
