After reaching a maximum timeout of 60 seconds, a major timeout occurs.By default, a major timeout causes the client to print a message to the console and start Part of tuning an NFS network is ensuring that clients are well-behaved so that they do not flood the servers with requests and upset any tuning you may have performed. Quote Postby nunolf » 2009/04/13 11:43:46 BTW, how can I post to the mailing list well formated console output, as you did with the netstat command?Cheers,N. If a reply is not received from the server within the RPC timeout period, the request is retransmitted subject to the timeout and retransmission parameters for that mount point. weblink
Also, what happens if you try to do an NFS mount manually? Thus, if a process attempts, for example, a write to a remote server and that server is unreachable, the user's application hangs and the user can't do anything to abort the Red Hat may request a vmcore from an NFS Client or NFS Server at a later date if it is believed there is a specific bug within RHEL, but a vmcore Ultimate Australian Canal Are people of Nordic Nations "happier, healthier" with "a higher standard of living overall than Americans"?

On NFS server I see the following string in the log (192.168.1.145 - is my host with Xenserver installed): daemon.notice<29>: Jun 9 14:46:04 xnas mountd: authenticated mount request from 192.168.1.145:838 for

Again, the most important thing you could probably change is to us tcp instead of udp. I currently have 4 x 2TB hard drives in Raid1 configuration.FreeNAS is now my "live" backup solution.I still have an off site backup solution in place as well. Mount.nfs Connection Timed Out Centos Slow server compensation The RPC retransmission algorithm cannot distinguish between a slow server and a congested network.

I specified the vers=3 option, because I understand QNAP does not support NFS V4 by default and NFS V3 suffices my requirement. In the previous example, badxid is nearly a third the value of timeout for connection-oriented RPC, and nearly half the value of timeout for connectionless RPC.

If your network connection to the server is flaky or goes through a loaded router, you may either increase the initial timeout using the timeo option or hard-mount the volumes. Nfs Timeo Because certain NFS operations take longer to complete than others, Solaris uses three different values for the minimum (and initial) timeout of the various NFS operations. The numbers in parentheses are the actual times in milliseconds; the other values are unscaled values kept by the kernel and can be ignored.

Is it possible to set a composite NOT NULL constraint in PostgreSQL What do you call this alternating melodic pattern? Because of the write-behind introduced by the buffer cache, this error condition is not propagated to the process itself before it calls the write function the next time, so a If the server does not respond to the first few RPC requests, it is likely it will not respond for a "long" time, compared to the RPC timeout period.
