Here is your
answer taken from a document that helped me with the same question… http://www-106.ibm.com/developerworks/library/l-lvm2.html 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, I'd type:
-----Original
Message----- 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.
