Matt,
you didn't need to export the volume group unless you want to move it to
a different system. It looks like you exported the VG and removed /dev/hdj1,
right?
If that assumption is true, you still need /dev/hdj1 in order to get your
VG back.
Then do the following:
# vgimport garage /dev/hd[efgj]1
# vgchange -ay garage
# vgreduce garage /dev/hdj1
That should bring your VG back and reduce it by the empty /dev/hdj1
physical volume.
You can physically remove /dev/hdj1 afterwards if you want to.
