no. not exactly.
sounds like you forgot to resize2fs the filesystem prior to the reduction. That
is a non-recoverable, catastrophic, mistake. You will need to recover from your
most recent backup.
you *may* be able to mount the non-fsck filesystem and copy it somewhere. do not
expect that everything will be recovered, from what you have described, it is
likely that any files that were in the extends that you gave up will be
corrupted. in fact, the copy of those files will fail because the blocks that
the file used to be in is no longer balled to the block device.
but you *may* be able to recover other files, before you go about the business
of rebuilding and reconstructing your lvm...
All the best,
