failed a disk of LVM

Hello,

I have a logical volume (LV) with four physical volumnes (PV):
hda1, hdb1, hdc1, hdd1.
Yesterday a PV failed. (hdc1).

could I recover the information?

Thanks

Plane A: Take it from an up to date backup. (If you don't have one, try
to get one next time)
Plane B: get a disk the same size (or better 4 disks the same size as
hda, hdb, hdc and hdd) and ddrescue hdc to the new disks. Than try to reactivate your backup version.
Plane C: force LVM to work without the broken drive (might work if you
had no data on hdc1)

Than make a full backup (plane B and C only), replace hdc, make a RAID5 and restore the backup.
