I just picked up a new Drobo 5N. I want to copy all the files from my old NAS onto the Drobo. There are just under 2TB of files on the old NAS.
To minimize the network load, what I’d like to do (unless anyone has a better suggestion) is to log into the Drobo, mount the old NAS, and issue the rsync command to copy everything. That way, the files are all transferred directly from the old NAS to the new NAS, without having to go through a laptop or workstation.
I have installed openssh, screen and rsync.
I have created the target directory /mnt/old_nas
However, the mount command isn’t working. The command
mount -t cifcs //old_nas_server/Volume_1 /mnt/old_nas
results in an error “No such device”. If I change it to
mount -t cifs //GUEST@old_nas_server/Volume_1 /mnt/old_nas
I get the error “No such file or directory”.
I’ve also tried adding the following line to /etc/fstab:
//old_nas_server/Volume_1 /mnt/old_nas cifs rw,users,nosuid,exec,auto 0 0
but I get the same “No such device” error.
Question 1: Is my approach the best way to minimize network traffic?
Question 2: If so, any suggestions on how to get mount to recognize the old NAS?
