We have file perm issues with our SAN. Basically our SAN doesnt like SMB 2 from our Macs, so we use SMB 1 (slower, but less corrupty..). We are moving away from this SAN shortly though.
While the Mac Pro is capable of 64-bit multiple processor supercomputing, there have been few professional-level graphics cards available for this system. Mac Pro users have faced a troubling paradox for some time. Fx 4800 for mac. This is like driving a Formula One race car but being restricted to 50 mph.
I have had nothing but trouble with SMB (Windows Sharing) services in Mac OS X Server 10.7. These problems were supposedly solved in 10.7.3, but my particular issues seem to still be there in several cases (Windows XP name browsing not working, Guest access not working, performance issues, dropped connections), and may be related to the Windows XP (versus Windows Vista/7) clients I'm dealing with. MacOS Server, formerly named Mac OS X Server and OS X Server, is a discontinued, stand-alone server operating system by Apple Inc.It is also the name of its replacement software, an operating system addition, for macOS that provides additional server programs along with management and administration tools for iOS and macOS.
I ensure this command is ran on all of our clients (either on the base image, deployment workflow or sent our via ARD terminal command)
sudo sh -c 'echo '[default]' >> /etc/nsmb.conf; echo 'smb_neg=smb2_only' >> /etc/nsmb.conf'
this forces SMB2 on the client
you can then view the share connection with this command:
smbutil statshares -a
which shows what flavour of SMB is being used.
To remove the nsb.conf file and revert back to defaults, use this command :
Mac Os Smb Client
