[linux-lvm] Destroyed partition on one PV

I went through this once before a long time ago, but can't seem to find the
notes on what I did. So, asking again (sorry):
I have (had?) a vg with 5 pv's, and one lv with 3 of those. I accidentally
(isn't that always the case) destroyed the partitions on 1 of them, and
maybe some of the data as well.
I tried to recreate one of the pv's:
[root at elmer ken]# pvcreate --uuid "LTXsEX-QpJN-tM2F-2CP1-wHSP-JcUa-Rnnlju"
--restorefile /etc/lvm/archive/VG_NAS_00003-846081755.vg /dev/sdb
Couldn't find device with uuid LTXsEX-QpJN-tM2F-2CP1-wHSP-JcUa-Rnnlju.
Couldn't find device with uuid Tnw4jr-SPj1-ChV7-k6Rz-ytWt-MtDD-lHso13.
Couldn't find device with uuid GQivgz-fh47-z2pF-kWQD-4khT-aRKz-flcvIs.
Couldn't find device with uuid 67IRC3-kmhr-Lo94-N4H4-C6mJ-NkZ7-KVEubc.
Device /dev/sdb not found (or ignored by filtering).
[root at elmer ken]# fdisk -l /dev/sdb

Not good is it. I get the same thing for the other drive.
I think last time I just bit the bullet, and activated the partial VG/LV,
ran e2fsck to fix what was left of the filesystem, with files recovered
Is that the best solution?
Any help with this would be greatly appreciated.
