Igor, the trick is to partition the iSCSI device. I have not done this
with iSCSI but have with a Fibre Channel SAN.

You made sdb  a PV. LVM cannot resize a PV.
If you partitioned sdb and made sdb1 a PV then you could using iSCSI
resize sdb, then make a new partition from the new free space on
sdb... lets call this sdb5 (logical partition). Then pvcreate
/dev/sdb5 then vgextend your VG onto /dev/sdb5 then resize the LV then
grow the filesystem.

The problem may be that you need to reboot to get the kernel to
re-read the partition table...

Alternativly present a new iSCSI LUN lets call this sdc. Make a PV on
that and add that PV to the VG... then resize the LV then grow the
filesystem.
