It would be well worth trying out the patch for bz #245832 to see if that fixes this problem too. Is this one now verified that it is not #245832? Created attachment 159101 [details]
patch to fix the problem--try #1
This patch seems to fix the problem. It was written by Steve Whitehouse
with some tweaking by me.
The code was looping in the relatively new section of code designed to
search for and reuse unlinked inodes. In cases where it was finding an
appropriate inode to reuse, it was looping around and finding the same
block over and over because a "<=" check should have been a "<" when
comparing the goal block to the last unlinked block found.
Fix was tested on the roth cluster using QE's revolver test. I posted the patch to cluster-devel for inclusion in the upstream kernel and to rhkernel-list for RHEL51. I'm changing the status to POST and reassigning to Don Zickus. in 2.6.18-35.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2007-0959.html |
