Hi Chen,

You need to define what account is used for accessing the NFS mount on your server.

These are commands I have in my startup script to NFS mount our Linux file server:

# Set the UNIX uid/gid to the EPICS account
nfsAuthUnixSet("corvette",401,400,0,0)

# Mount drives with NFS
nfsMount("corvette","/home","/corvette/home")
nfsMount("corvette","/home","/home")

You also need to make sure that in your /etc/exports file you are exporting the file with rw/ permission for that IOC:

/home millenia(rw,async) \
      ioc13lab(rw,async) \
      ioc13lab2(rw,async) \
      ioc13bma(rw,async) \
      ioc13bmc(rw,async) \

Mark

Hi,

I have mounted my crate to a work machine. It can create directory and 
view directory in that machine, but can't write to file. Please see below,

iocbio4> mkdir("/home/ioc/landahl/test")
value = -1 = 0xffffffff = engineer + 0xe1134937

[ioc@zim landahl]$ ls -al test
total 8
drwxr-s--- 2 ioc biocat 4096 Jun 29 08:43 .
drwxrwsrwx 4 ioc biocat 4096 Jun 29 08:43 ..

iocbio4> copy("/home/ioc/landahl/testfile.txt", 
"/home/ioc/landahl/testfile1.txt")
Can't write to "/home/ioc/landahl/testfile1.txt"
value = -1 = 0xffffffff = engineer + 0xe1134937

where file testfile1.txt is empty.
-rw-r----- 1 ioc biocat    0 Jun 29 08:43 testfile1.txt

Could someone help me figure it out?

Many thanks,

Chen
