fatal error while init the repo on a nfs mounted drive

fatal error while init the repo on a nfs mounted drive

        i am trying to initialize a repo (for yocto development - but it seems to be using the same infrastructure as android). 


since I lack space on the OS drive, I nfs mounted another disk 
(filesystem is ext4 but that probably is irrelevant on the mount-client 
side).


I try to initialize the repo with the command


./repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b dylan


and get the error


fatal: unable to start /mnt/lvm/public/.repo/repo/main.py
fatal: [Errno 13] Permission denied


Permissions are fine on the disk. manually I can do file operations without a problem.


Is it impossible to have the repo on an nfs drive (even at the penalty of slower processing)?


Thank you for your help

I never tried this setup; I use sstate in NFS in some customers but not
full build system.

I have never tried it as well, but error -13 from NFS when mounting 
rootfs is usually associated with missing 'sudo 
/etc/init.d/nfs-serverXXXX restart'

Double check your /etc/export configuration

I just tried this and it worked fine.

When you say permissions are fine, did you check it from the
NFS client side?  The error you are getting says that they are
not.  Also, are you running selinux?  If so, make sure that's
set up properly as well.

Thank you all for your responses.

I suspect some incompatibility in nfs server - client. 
The storage server is running slackware v14 with exports file

       /mnt/lvm starland.skails.home(rw,no_subtree_check,no_root_squash) 

,while the client is a linux mint. 
and I usually have to do the mounting on mint as 

       sudo mount -o vers=3 stargaze:/nfs/lvm /mnt/lvm/

between slackware systems I never need to explicitly set the nfs version .

So with that aside, and having double checked the exports file 
I tried 'touch' and 'mkdir' from the client side (of course!). I can create files and folders so I presume I don't have permission problems...

Anyhow, since Gary provided proof that it works over nfs, I'll  keep on looking for the fault.

Otavio, I have already moved the $SSTATE_DIR to this same nfs exported dir , as per your previous suggestion (in an earlier post) but it doesn't seem to be enough.  Either way I am using a VM for the development system so I am already suffering from slow builds even without the nfs. I believe build time will become marginally worse.

Thank you all once again.

just aheads up. 
and perhaps info useful to some.
seems that using the nfs option 'async' did the trick.
