+++ This bug was initially created as a clone of Bug #155021 +++ From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050323 Firefox/1.0.2 Fedora/1.0.2-1.3.1 Description of problem: An up to date Fedora Core 3 machine mounts my home directory from a NFSv4-server. When "draging and drop"-copying 100 files at the same time from a file /tmp/r/a.tar.gz opened in file-roller to a nfs-directory ~/nfscrash10 opened in nautilus, the copying stops after about half of the files showing a pop-up window with a progress bar. windows title: "Copying files." window content: "Files copied: 43 of 100 Copying: a47 From: /tmp/fr-XzJiHU/a To: /nfs/home/others/esjolund/nfscrash10 " and there is a cancel push-button. Pressing cancel just makes the window not being repainted. Any process accesing my nfs home directory hangs from now on. For instance typing "ls ~" on the command line will just leave the ls-process hanging. Executing the command "ps auxw", I found out that many of the processes with my uid are in the "D"-state ( uninterruptible sleep ). The only way to get out of the situation tend to be to reboot the machine. Version-Release number of selected component (if applicable): nfs-utils-1.0.6-52 How reproducible: Always Steps to Reproduce: 1. login with kde 2. on the command line type: mkdir ~/nfscrash10 3. on the command line type: nautilus ~/nfscrash10 4. on the command line type: file-roller /tmp/r/a.tar.gz You now see that file-roller expands the a.tar.gz file. File-roller will show you the directory "a" which resides in a.tar.gz. 5. open the directory "a" in file-roller. Now the 100 files from a.tar.gz is visible in file-roller. 6. ctrl-a (select all) 7. press left mouse button and drag the files to the nautilus window. 8. release left mouse button A pop up window shows you the progress of the copying. After copying about half of the files, the copying seems to stop. 9. Because nothing seems to happen I press cancel in the pop up window. Actual Results: Processes accessing nfs home directory now hangs. Some processes are in the "D" running state ( uninterruptible sleep ). Expected Results: Processes should not hang. Additional info: Oxygen is the hostname of my machine ( the nfs client ). [esjolund@oxygen ~]$ grep nfs /etc/auto.nfs home -rw,fstype=nfs4,hard,intr,nosuid,tcp nfs.sbc.su.se:/home [esjolund@oxygen ~]$ uname -a Linux oxygen 2.6.11-1.14_FC3 #1 Thu Apr 7 19:23:49 EDT 2005 i686 i686 i386 GNU/Linux I also did echo t > /proc/sysrq-trigger The resulting log from /var/log/messages will be attached to the bug report.
It appears we are not recovering from NFS4ERR_DELAY errors. This will need more investigation...
