I've a VE with several nfs3 mounts (not bind mounts), i recently got a problem accessing just one nfs mount point.
# mount -t nfs | grep /home/studies
netapp3:/vol/vol0/studies on /home/studies type nfs (rw,nosuid,bg,soft,tcp,rsize=8192,wsize=8192,addr=132.72.40.11)
# ls -la /home/studies/
/bin/ls: cannot access /home/studies/: Input/output error
#
There is no problem unmounting /home/studies/, but after i mount it again the problem persists. I've also restarted the VE and the problem still persisted. Then i've migrated the VE to other node in the cluster and the problem was gone, so i've migrated it back to the same node and the problems was still there. So i've checked
other VE on this node which have mounted /home/studies/ and they all have problem accessing only this /home/studies/ share. So this looks like the whole HN node has got into some bad state regarding nfs3.
Is there a way to solve the problem without node reboot?
And do you need more info possibly find what actual problem or bug is it, while I still have not rebooted the node?
I'm using vanilla openvz 2.6.18 028 kernel.
Thanks
Alex
