Description of problem: After configure nfs kdump server on rhevh, it created /var/crash/var/crash/ directory on kdump server and saved vmcore file to this directory. It's better to use /var/crash/ and saved vmcore file to /var/crash/. Version-Release number of selected component (if applicable): rhev-hypervisor-6.1-20110506 How reproducible: Always. Steps to Reproduce: 1. configure nfs kdump server on rhevh 2. reboot 3. kdump service is starting, echo c> /proc/sysrq-trigger Actual results: vmcore file is saved to /var/crash/var/crash/ Expected results: vmcore file is saved to /var/crash/
this is more a feature of kdump we can't necessarily change, it will put the vmcore under <mountpoint>:/var/crash. To get it just under /var/crash we would need to set kdump to just /. If / isn't exported on the nfs server it will fail. Exporting / over nfs isn't gonna be common if not a security issue, may just need to put a release note in and file a bug to put a hardcoded directory into kdump options.
ok, this is even documented in man kdump.conf: net <nfs mount> Will mount fs and copy /proc/vmcore to <mnt>/var/crash/%HOST-%DATE/, supports DNS. Note that a fqdn should be used as the server name in the mount point
