dmesg: "nfs: server [...] not responding, still trying"
Hi all,
Several days ago I did a clean reinstall of Fedora 9. For some reason, I am now having problems with NFS that I didn't have previously. venus is my FreeBSD v7 server. I have this line in the fstab of my F9 client: Code:
venus:/media/disk8 /media/disk8 nfs defaults 0 0 Code:
nfs: server venus not responding, still trying I haven't had these issues previously with this server, nor have I seen the same problem with another client running Ubuntu. Any ideas? |
What about server messages?

So just to clarify, You had this working fine at one point on Fedora 9, but reinstalled F9 onto the same host? Are you sure you installed the same config? Especially iptables (Linux Firewall)?
I'm not sure if Fedora defaults to NFS 2 or 3, but I would try forcing NFS 3 and TCP. I usually use "bg,rsize=32768,wsize=32768,nfsvers=3,tcp,intr" instead of "default" |

It is not a firewall issue as I don't use one on the Fedora client, rather I use PF on the FreeBSD box, which also serves as a gateway. The other odd thing is that I am not seeing any such errors on Ubuntu client accessing the same NFS shares. It seems to be specific to this Fedora box. Quote:

[quote=Kropotkin;3269796]I am seeing very sporadically some lines like this:

I'm not totally adjusted to BSD, but I believe you need to prefix the device name with "r" (for raw) and maybe postfix with "c" (on Solaris, this was for historical reasons the "entire disk"). So, maybe /dev/rad2c? |
solved apparently
Hi again everyone,
About a week ago I upgraded the kernel on F9 system to v2.6.26.3-29 and I haven't seen this issue (NFS timeouts on the client) since. It appears that it was related to the earlier kernel, v2.6.25.14-108. In any case, thanks for the feedback. |
