Hi All - On a Linux email server (postfix/courier-imap) I'm NFS mounting /home and seeing the occasional error like:
Jun 5 11:37:06 localhost kernel: [ 9924.401601] nfs: server 192.168.18.2 not responding, timed out At first I suspected network issues, so to isolate that I've put in a crossover cable between the two hosts and setup a dedicated private network just for NFS. Problem still happens. Next I read that perhaps higher rsize and wsize arguments could cause this, especially due to bad network equipment, so I went ahead and tried rsize/wsize=1024 instead of 4096, no dice. Finally I was mounting the shares as "sync,soft" which could be bad for email, so I changed that to "sync,hard,intr", but still no dice. These errors don't seem major, but I'd like to get them fixed. Users occasionally see a error on their mail clients when connecting to IMAP. /etc/exports on the server: /home 192.168.18.1(rw,sync,no_root_squash) 192.168.19.1/24(rw,sync,root_squash) /etc/fstab on the client: 192.168.18.2:/home /home nfs rw,sync,auto,hard,intr,rsize=1024,wsize=1024,timeo=14 0 0 Any suggestions? It's been a while since I've done anything major over NFS, so I'm sure I'm a bit rusty. If it helps the client server is Ubuntu Dapper Server (6.04) and the server is Ubuntu Hardy Server (8.04). Neither server get's very loaded... no errors on the network devices via ifconfig, etc. Thanks!
