Hello, we have a weired problem with Linux NFSv4.0 Server (Vanilla Kernel 4.1.6) and a Sun Solaris 10 client (all patches applied): When mounting a share on the Solaris client and then rebooting the client without unmounting the share first, after the reboot every attempt to mount the share again gives an I/O error on the client and the mount fails. After a long time (serveral hours) the v4 mount suddenly works again. Mounting a share with vers=2 works always even in times when the v4 mount fails. So it seems the Linux NFSv4 server holds a state for the client which prevents the re-mounting of the share and gives the I/O-error on the client. We use NFSv4 without idmapd. Is there any tip how to debug or solve this? Thank you and best regards -Ulrich -- |----------------------------------------------------------------------- | Ulrich Gemkow | University of Stuttgart, Germany | Institute of Communication Networks and Computer Engineering (IKR) |----------------------------------------------------------------------- -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
