Sounds like your hard drive or the controller are having issues. By any chance is/var on sda. XFSdump keeps a catalog in /var/lib/xfs which is used for incremental backups. I know this because about 3 or 4 years ago I had to file a bug ticket with Red Hat for RHEL 6 about improper selinux contexts on that directory.
