XFS filesystem goes read-only when copying large files with Red Hat Enterprise Linux 5.4 and md-raid5

Issue

• Cannot write to an XFS filesystem mounted on md-raid5 storage during large copy.
• Copying large files to a XFS filesystem fails with backtrace in messages file. XFS filesystem detects inode btree corruption and shuts itself down.

• Messages are visible in /var/log/messages file :
