find prints hard link count warning for /proc
Last modified: 2007-11-30 17:11:35 EST
Description of problem: A user running find on /proc (or /) will see this warning message some of the time. find: WARNING: Hard link count is wrong for ./2733/task: this may be a bug in your filesystem driver. Automatically turning on find's -noleaf option. Earlier results may have failed to include directories that should have been searched. Version-Release number of selected component (if applicable): Linux packetbane 2.6.17-1.2139_FC5 #1 SMP Fri Jun 23 12:40:11 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux findutils-4.2.27-4 How reproducible: About 20% of the time when running find. Steps to Reproduce: $ find /proc -name asdf Additional info: It curiously only seems to warn for the same file (2733/task) when it happens. This is the java process running for FC5's azureus. The task subfolder contains entries for 50+ threads. This issue was discussed in another bug (162418) but doesn't seem to have come to any real resolution, and a note was left saying to file a bug if it was seen on newer kernels. It's unclear whether there is any actual kernel bug involved or not, so I'm reporting, assuming this could still be an actual problem.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
