Hi,
I am trying to export a memory-based file system via NFS. However, I am
not able to do with either ramfs or tmpfs. Here is the reported error.
Is there a protection in NFS server to prevent this?
I also tried to use ramdisk. That worked, however, I am not able to
create a ramdisk of more than 1G. I need to create a ramdisk that is 2G
or more. Any insights on this.
I will be happy if I can get solutions for either of the approaches. Or
is there any other alternatives?
Thanks,
Weikuan
[root@yoda1 ~]# mount -t tmpfs none /nfs
[root@yoda1 ~]# df -h /nfs

-bash-3.00# mount 192.168.1.254:/nfs /nfs
mount: 192.168.1.254:/nfs failed, reason given by server: Permission denied

You might try exportfs(8)'ing the file system before trying to mount it...

Thansk for your prompt reply. Forgot to add that they are exported. Here
is the output from exportfs. The problem is I can nfs-mount /data
(/dev/hda2) fine, but not /nfs (tmpfs).
Weikuan
-bash-3.00# exportfs
/nfs 160.91.202.127/255.255.255.128
/data 160.91.202.127/255.255.255.128
/nfs 192.168.120.*
/data 192.168.120.*
