[linux-lvm] Need help with lost XFS file system

I have an LVM2 xfs file system that spans two partitions: /dev/sda4
(150GB) and /dev/sdb1 (300GB). /dev/sda also hosts my O/S (/dev/sda1 is
/boot and /dev/sda2 is root).
Apparently, something went amiss with the /dev/sda disk, and the first
indication was a hung system, followed by the loss of certain O/S files in
the /lib directory following a reboot. I was hopeful that the damage was
limited to the O/S files, so, after much troubleshooting and fschk attempts,
I just reinstalled the O/S. After the O/S reinstall, I was finally able to
reboot the machine and try to run an xfs_check and xfs_repair -L. Anyway,
vgscan, pvscan, and lvscan all look good. Nothing seems wrong from this
standpoint. The file system mounts, but it takes forever to do so. And
when I try to ls the files, I get an Input/output error. If I unmount and
run an xfs_repair, I get a bad magic number or some such message.
Even if /dev/sda4 is a total loss, I am pretty certain that all the files
stored on the /dev/sdb1 are in tact, but the xfs file system just won't
mount properly. Is there anything I can do, or am I just screwed? Of
course, if I had a backup I would just use that, but there is none.
