You've created an XFS filesystem atop a concatenation of non-redundant
drives so this condition should not be unexpected.  It's not a directory
you want to salvage, but the files within it.  If they reside on sdc1
you're out of luck without using data recovery tools.  If they reside on
sdb1, sdd1, or sde1, then running xfs_repair might make the FS mountable
and get you access to them again.

That's assuming LVM is still running with one drive gone, or will still
assemble the concatenation with one drive missing.  I don't use LVM.

Cheers,
Stan
