is your answer taken from a document that helped me with the same
The extent size determines the maximum
size that a logical volume can be. As you can see from the above output, a 4
MB extent size imposes a logical volume size limitation of 256 Gigabytes,
which is an easily attainable logical volume size if you're adding several
high-capacity drives to your volume group. If your volumes could end up being
greater than 256 GB apiece, I recommend specifying a larger extent size at
vgcreate time. Extents can range anywhere from 8 KB to 512 MB, and must always
be a multiple of two. By increasing the extent size above 4 MB, the maximum
physical volume size will be scaled accordingly, up to a maximum of 1 Petabyte
(although the current real-world size limit is 2 Terabytes on x86 systems).
For example, if I wanted to create a volume group with 32 Megabyte extents,
# vgcreate -s 32M main /dev/hda5

What are the current limits
(specifically on LVM 1.0.5) of each volume/disk? I read 255GB in one of
the docs. Can anyone fill me in? Thanks.
