Both your attempt to mount NFS and SMB failed:
Jul 25 14:04:55 gbh-tower unassigned.devices: Error: shell_exec(/sbin/mount -t 'nfs4' -o rw,noacl 'COLEMITE:homes' '/mnt/remotes/COLEMITE_homes' 2>&1) took longer than 10s!
Jul 25 14:06:08 gbh-tower unassigned.devices: Error: shell_exec(/sbin/mount -t cifs -o rw,noserverino,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777,uid=99,gid=100,vers=3.1.1,credentials='/tmp/unassigned.devices/credentials_homes' '//COLEMITE/homes' '/mnt/remotes/COLEMITE_homes' 2>&1) took longer than 10s!
The mount commands both timed out. I would think right away that the remote server isn't responding to a ping, but if the orb turned green and the "Mount" button was active, that's probably not the issue.
Try using the IP address of CEOLMITE rather than the server name. When UD asks for the server, just enter the IP address.
