I have a new install of OMV running just fine except for the transfer speed that I am getting when trying to copy data from my OMV NAS to a removable 3TB drive housed in a Vantec 4 bay USB 3.0 cabinet. The file that I was testing is a 3.71 GB backup file. I takes 3 minutes, 21 seconds to copy the file from my OMV NAS to the removable vs 30 seconds from my windows box to the removable. I googled and found some references to this problem with throughput having to do with a bug in the linx kernel. I am not positive that this is my problem. I have pasted a log below of what appears on the console when I plug the drive in. It seems to be detecting it as a superspeed device, but then there are other messages that I am not sure the meaning of. If the kernel is the problem, how would I go about upgrading to a newer kernel, and if I did that, would it break anything in OMV?
Regards,
Tony
