problem with NFS (mount failed, reason given by server: Permission denied)

betsubetsu · #1 20th June 2008, 05:29 PM

After a brutal power shutdown, i am unable to nfs mount my directory.

in /etc/exports, i have

Code:

/home  *(rw,sync,no_root_squash)

after exporting with

Code:

exportfs -va

I still cannot mount from a client:

Code:

mount -t nfs myserver:/home /home
mount failed, reason given by server: Permission denied

All the necessary services are up and running:

Code:

# ps axf|grep nfs

Been a while since I played with NFS, but is there any further information in the logs?

actually the /etc/exports has the line

Code:

/home  10.0.21.*(rw,sync,no_root_squash)

and it did not work. I changed that line to

Code:

/home  *(rw,sync,no_root_squash)

and it start working again.

!!!!!!!!!!!!!!!!!!!!!!
