Hi Daniel,
Thanks for your reply. I tried the nfs hard mount, and got the same
behavior of the soft mount.
But in the /var/log/message, got nfs server recovery message which is not
printed when mounting as soft mode.
Dec 14 02:12:47 test-1 kernel: nfs: server ip not responding, still trying
Dec 14 02:13:39 test-1 kernel: nfs: server ip not responding, timed out
*Dec 14 02:14:34 test-1 kernel: nfs: server ip OK*
Dec 14 02:14:34 test-1 kernel: NFS: __nfs4_reclaim_open_state: Lock reclaim
failed!
According to my understanding the vm boot process will not recover(the vm
is still in running state, never paused) to normal until restarting the vm
guest.
And it is not the issue of libvirt or qemu, it is just the correct behavior
with the nfs connection timeout, right?
With 'hard' mount I would not expect QEMU/guest to see any errors
at all, though your messages here about 'Lock reclaim failed' are
a little concerning as it suggests something is not working right
wth NFS. This is beyond my knowledge of NFS though.
Regards,
Daniel
