Package: linux-image-2.6.26 Version: nfsfix.1 Severity: important
When an export is exported and mounted via autofs using BOTH NFSv3 and NFSv4 the NFSv4 one deadlocks. Setup - transition from v3 to v4. System A is still perusing the old map: cat /etc/auto.local | grep iPodResolution iPodResolution -rsize=4096,wsize=4096,rw eden:/exports/md4/videoiPod System B is using the newever version of same map with a v4 mount: cat /var/yp/auto.local | grep iPodResolution iPodResolution -fstype=nfs4 eden:/md4/videoiPod If system B is writing to the mount and A is reading from it B starts getting I/O errors/BAD FDs. If B is running from disk lots of things fail. If B is running diskless - total lock up. Same setup with V3 only has been working flawlessly for 5+ years. Same setup with V4 only (when the v3 machines are off) seems to work OK as well. Fairly easy to reproduce. I am not sure at this point if autofs has any role in this and I will not be in a position to retest until 19th. Apologies. Tested with: stock debian, older version with just the nfs regression fix, stock recompiled with preempt, 686 and 486 versions. -- System Information: Debian Release: 5.0.3 APT prefers stable APT policy: (500, 'stable') Architecture: i386 (i686) Kernel: Linux 2.6.26-2-686 (SMP w/1 CPU core) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages linux-image-2.6.26 depends on: ii coreutils 6.10-6 The GNU core utilities ii debconf [debconf-2.0] 1.5.24 Debian configuration management sy linux-image-2.6.26 recommends no packages.
