max_pe

[j773303]

Should data need backup and restore while increase max_pe ? Thanks,

vgcreate:
-e max_pe Set the maximum number of physical extents
that can be allocated from any of the
physical volumes in the volume group. The
default value for max_pe is 1016. However,
if the size of any physical volume exceeds
1016 times the pe_size, the default value for
max_pe is adjusted to match the physical
volume size. The maximum number of physical
extents can be a value in the range 1 to
65535.

max_pe for a vg can NOT be changed.
So either you'll have to accept not using all of the PV ( :-( ), or recreate the vg which would need a backup of each lv defined on it.

There has been several prior topics on this subject for example:

You can find all using the 'search' function.
Typically with 'more options', max_pe as search string, hpux as forum, 'subject only' for initial search.

hth,

practical max_pe can be changed by running vgcreate again.

That id a destructive process.
