RE: Xfs Access to block zero exception and system crash

["Sagar Borikar" <Sagar_Borikar@xxxxxxxxxxxxxx>]

Copy is of the same file to 30 different directories and it is basically
overwrite.

Here is the setup:

It's a JBOD with Volume size 20 GB. The directories are empty and this
is basically continuous copy of the file on all thirty directories. But
surprisingly none of the copy succeeds. All the copy processes are in 
Uninterruptible sleep state and xfs_repair log I have already attached 
With the prep. As mentioned it is with 2.6.24 Fedora kernel.

Thanks
Sagar

Copying the same file to the same directory, or 30 different files to 30
different directories?  Or the ame file to 30 different directories?  If
different directories what is the layout of the target directories?
Etc...
