Oh, just to let you know, the OS is based on Linux kernel 2.6 GPL Linux.
The system (NAS) was running for about a year before this happened.

I came across one thread on another website that another person having a similar problem was suggested to try vgscan from the lvm2 package, I'm not sure what that is, but thought I'd add it.

NAME
fsck.xfs - do nothing, successfully SYNOPSIS
fsck.xfs [ filesys ... ] DESCRIPTION
fsck.xfs is called by the generic Linux fsck(8) program at startup to check and repair an XFS filesystem. XFS is a journaling filesystem and performs recovery at mount(8) time if necessary, so fsck.xfs simply exits with a zero exit status. If you wish to check the consistency of an XFS filesystem, or repair a damaged or corrupt XFS filesystem, see xfs_check(8) and xfs_repair(8). FILES
/etc/fstab. SEE ALSO
fsck(8), fstab(5), xfs(5), xfs_check(8), xfs_repair(8). fsck.xfs(8)
