Note that I enclosed the 'disk' above within quotes. Different filesystems and mount points does not necessarily mean much in these days where a single storage array may be shared among multiple servers. As long as you are not using JBODs, i.e. you are on a SAN/NAS, there is no physical guarantee that the disks are where they purport to be. Can your SA verify that these 'disks' are actually different? A 'sar -d' during that period may reveal some interesting results.
