I have change my system from slackware to gentoo and I can't get my lvm to work.

When I run vgscan I get:

# vgscan 
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of volume group "ftp_vg" from physical volume(s)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume group

and pvscan:

# pvscan 
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/ataraid/disc0/disc"                is associated to unknown VG "ftp_vg" (run vgscan)
pvscan -- inactive PV "/dev/ide/host2/bus1/target0/lun0/disc"  is associated to unknown VG "ftp_vg" (run vgscan)
pvscan -- inactive PV "/dev/ide/host2/bus1/target1/lun0/disc"  is associated to unknown VG "ftp_vg" (run vgscan)
pvscan -- inactive PV "/dev/ide/host2/bus0/target1/lun0/disc"  is associated to unknown VG "ftp_vg" (run vgscan)
pvscan -- inactive PV "/dev/ide/host0/bus0/target1/lun0/disc"  is associated to unknown VG "ftp_vg" (run vgscan)
pvscan -- total: 5 [496.34 GB] / in use: 5 [496.34 GB] / in no VG: 0 [0]

And now to my problem.
when I used slackware all my pv's was located by pvscan at /dev/hdb and forward but now at /dev/ide/host?/bus?/lun0/disc.

So if anybody got a clue how to fix it, pleace tell me.

What kernel are you using? Does it have device mapper enabled? Have you
tried vgcfgrestore ? IIRC On LVM1, that's vgcfgrestore -n <physical volume> ,
on LVM2 it's vgcfgrestore <volume group name>
