vgextend-Too many physical extents

[Kim Kendall]

I was changing the alternate path to be the primary, so I did a vgreduce to remove the (old) primary, and then vgextend to add it back to make it the alt path.

When I vg extend it back in, I get :

vgextend: Too many physical extents for volume group.
Cannot add physical volume to volume group.
LVM_MAXPXS: 65535

( I also tried vgextend )
vgextend /dev/vgemcdbf04 /dev/dsk/c17t0d1 /dev/dsk/c16t0d1

Which returns the same thing.

Sorry ... fingered it out...

vgchange -a y - wouldn't work either

Rebuilt the lvmtab and then vgchange worked and the new alt path is there.

Hi,
Another way to get it work is
#mv /etc/lvmtab /etc/lvmtab.old
#vgscan
It will add the alternate link.
But you may get same primary path as it was .
Just give it a try.
