help mounting /usr via nfs on remote client

GUIPenguin · 03-22-2006, 08:48 AM

I have a diskless node booting and everything works fine.. except I can't get anything else to mount besides the enitial shared root.

Here is my masters /etc/exports

Code:

/diskless/node02   192.168.1.3(sync,rw,no_root_squash,no_all_squash)
# common to all slaves
/usr   192.168.1.0/24(sync,ro,no_root_squash,no_all_squash)

Here is my node02's /etc/fstab

Code:

master:/diskless/node02         /         nfs     sync,hard,intr,rw,nolock,rsize=8192,wsize=8192    0 0
master:/usr                     /usr      nfs     sync,hard,intr,ro,nolock,rsize=8192,wsize=8192    0 0
none                            /proc     proc    defaults                                          0 0

these examples came from diskless nodes with gentoo http://www.gentoo.org/doc/en/diskless-howto.xml

/usr will NOT mount

how can I get this so I can mount /usr ro from my master? And yes I have created a /diskless/node02/usr directory.

hi,
here is my /etc/exports:

Quote:

/ 192.168.0.2(rw,nohide,no_root_squash,sync)
/root/Desktop/MyComputer/hd 192.168.0.2(rw,nohide,no_root_squash,sync)
/root/Desktop/MyComputer/C 192.168.0.2(rw,nohide,no_root_squash,sync)
/root/Desktop/MyComputer/D 192.168.0.2(rw,nohide,no_root_squash,sync)
/root/Desktop/MyComputer/E 192.168.0.2(rw,nohide,no_root_squash,sync)
/root/Desktop/MyComputer/F 192.168.0.2(rw,nohide,no_root_squash,sync)

look at the first entry. Here i'm mounting the '/' with "nohide" parameter......hence all linux directories under '/' are visible remotely.
and in rest of the lines i've mounted the "mounted" drives.

hope this will help u.

regards

Thanks...can you also please post your /etc/fstab of your remote computer.. I believe its my fstab becasue it jsut wont mount my exports on boot.. yet I can mount them with mount master:/usr /usr

sorry brother. I don't mount that on booting i.e don't have any entry in /etc/fstab.
i use the following command to mount manually:

#mount 192.168.0.2:/ /mnt/localhost

where 192.168.0.2 is the IP of the remote machine and u must have gussed that /localhost is dir which i made in local computer for mounting the remote one.

The reason for not mounting on booting is that suppose the remote machine is down......then this local computer takes time to boot up. It hangs for a while when reading /etc/fstab.

thanks. I just decided to move the files and libs I needed and nothing more into my shared root for my diskless client to support gcc and distccd. Works now
