Description of problem: Using kernel-PAE-2.6.32.12-115.fc12.i686 the server IO requests hang for 60-120 seconds under high IO load. CIF clients see... CIFS VFS: No response for cmd 50 mid 4xxxxx (repeats with increasing 4xxxxx number) CIFS VFS: Send error in SETFSUnixInfo = -11 (repeats again from the start) NFS clients also see the problem (i.e. it is not just a samba related issue). Version-Release number of selected component (if applicable): kernel-PAE-2.6.32.12-115.fc12.i686 How reproducible: Boot the kernel-PAE-2.6.32.12-115.fc12.i686 kernel Steps to Reproduce: 1. Run three rsync programs on clients copying data from the server to local disks 2. Run two cp -r of 20 Gb directories on clients copying data from a cifs share mounted from the server on to a local disk 3. Run two cp -r of 20 Gb directories on clients copying data from an NFS mounted area from the server on to a local disk Actual results: Any program accessing the samba share from Windows will hang Expected results: Additional info: Problem vanishes if I boot the slightly older kernel kernel-PAE-2.6.32.11-99.fc12.i686
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
