Description of problem: When entering "mail" at the shell's command-line prompt, I get an error msg Unable to lock mailbox: Input/output error and an exit status of 1. Version-Release number of selected component (if applicable): mailx-12.5-3.fc15.i686 How reproducible: Type the "mail" or "mailx" command at the shell's command-line prompt. Steps to Reproduce: 1. Type the "mail" or "mailx" command. 2. 3. Actual results: An error msg Unable to lock mailbox: Input/output error and an exit status of 1. Expected results: The usual list of mail msgs, or a msg "No mail for joeuser" Additional info: We are NFS-mounting a mail spool directory. The problem does not occur when running the "mail" command directly on the machine containing this directory. The problem only occurs on machines that are NFS-mounting the mail spool directory. This problem did not occur with previous versions of Fedora; it only occurred when we upgraded from Fedora 14 to Fedora 15.
Also seeing the same issue with a fedora 15 server and client. I no longer seem to be able to use the "nolock" option to NFS, which may be what is causing this issue?? I can specify "nolock" as an option to the mount, but it seems to not be honored, since it doesn't show up in the options running "mount" after the filesystem is mounted.
Hello guys, please, do you still see this issue? I've try to reproduce it, but with no luck: $ rpm -q mailx mailx-12.5-3.fc15.x86_64 $ mount | grep spool 10.34.4.205:/var/spool on /var/spool type nfs4 (rw,relatime,vers=4,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.34.4.247,minorversion=0,local_lock=none,addr=10.34.4.205) $ mailx No mail for joe
The problem seems to have gone away in Fedora 16.
Thank you Art. Closing this as NEXTRELEASE.
