From Bugzilla Helper: User-Agent: Mozilla/4.79 [en] (X11; U; Linux 2.4.18-19.7.x i686) Description of problem: Hi, I NFS mount my mail server (a Redhat 8.0 system running with the latest patches). If I reboot the mail server, my desktop boxes lock up. I'm mounting mail with "-o rw,bg,soft,timeo=3,retrans=3" (and I've even tried adding "intr", although it shouldn't make any difference). If I'm sitting in /var/mail on the client when the server goes down, and I type "ls", my shell locks for an indefinite amount of time (and I cannot interrupt it even though I specified "intr") before displaying ".: Input/output error" -- as I expect it to -- (sometimes it returns quickly, other times it never returns). Help? ...dave alden Version-Release number of selected component (if applicable): kernel-smp-2.4.20-9 How reproducible: Always Steps to Reproduce: 1. On "client", mount "server"'s /var/mail and cd into it: # mount -o rw,bg,soft,retrans=3,timeo=3 server:/var/mail /var/mail # cd /var/mail 2. On "server", halt it # halt 3. Back on "client", type ls # ls The amount of time it takes to respond varies greatly, and I cannot interrupt it with ^C. Actual Results: The system hangs for an indefinite amount of time and interrupting it (with ^C, yes I check what "intr" was with stty -a) doesn't work. Expected Results: 2 issues: 1) I should be able to interrupt it with ^C, shouldn't I? 2) Shouldn't it return in basically the same amount of time each time I try this? Additional info:
This io errors is coming from the soft mount, try using hard,intr as the mount options.
