I'm having trouble enderstanding Linux path for DM

I set this

GW system is stored on SYS1: ie. SYS1:gwsys
so Domain is SYS1:gwsys/gwdom
Post Ofice is SYS1:gwsys/gwpo
Library is SYS1:gwsys/lib

For Library storage area I set the linux path in consoleone to
/media/nss/SYS1/gwsys/lib

note: can't save with no unc path in windows field so I put in
\\server\sys1\gwsys\lib
but consoleone on linux automatically converted this to
/media/nss/SYS1/gwsys/lib...

problem is when I try to create a document I get an c081 error

can anyone point me in the right direction - have I setup correctly ?
or is there some other issue
