[linux-lvm] About Extending LVM size with Hardware Raid

I have a similar system - a fibre channel RAID box. I added a disk to it
and expanded the RAID5 device, then used the scsiadd command to rescan
the device. If your card emulates a SCSI disk, this may work. Otherwise,
try unloading/loading the kernel driver module(if possible), and failing
that a reboot should work.

Anyway, the new size was reported correctly as 1.25Tb, so I then used
pvresize to grow the pv to the new size of the device.

At this point, pvresize reported "Command not implemented yet".

/sigh/
