Unable to mount nfs share under rescue in VM
 
Dear All,

I have shared few directories through nfs in my fedora 12 OS.

Here is the output of few commands from the virtual machine running on CentOS in both normal and rescue mode

Code:
[root@localhost /]# showmount -e 192.168.0.3
Export list for 192.168.0.3:
/home/vinay/Desktop    *
/var/www/html/cdrom/iso *
Code:
[root@localhost /]# rpcinfo -p 192.168.0.3

I am able to mount Both the shared directories when VM is running normally.

When I enter rescue mode in CentOS VM. I started Networking, I have checked network connections. Also I am getting above outputs for rpcinfo and showmount commands in rescue mode as well.

But when I fire

Code:
mount -t nfs 192.168.0.3:/var/www/html/cdrom/iso /mnt
It just hangs like this...What could be the reason ?

Can anyone please help me with this ?

Isn't rescue mode's default to put the filesystem in read-only mode? Have you checked that you've remounted the system as read-write?

Thanks for reply arashi256.

But even in rescue mode /mnt directory is with rw mode. I checked with mount commmand

Still No luck in mounting nfs filesystem in rescue mode...
