With the default settings (PE size of 4 MB) there is a limit of 256 GB
per LV in current LVM versions (1.x series). For such a large LV choose
a larger PE size at vgcreate time. From its manual page:
-s, --physicalextentsize PhysicalExtentSize[kKmMgGtT]
Sets the physical extent size on physical volumes
of this volume group. A size suffix (k for kilo
bytes up to t for terabytes) is optional, megabytes
is the default if no suffix is present. Values can
be from 8 KB to 16 GB in powers of 2. The default
of 4 MB causes maximum LV sizes of ~256GB because
as many as ~64k extents are supported per LV. In
case larger maximum LV sizes are needed (later),
you need to set the PE size to a larger value as
well. Later changes of the PE size in an existing
VG are not supported.
