Sets the physical extent size of PVs in the VG. The value must be either a power of 2 of at least 1 sector (where the sector size is the largest sector size of the PVs currently used in the VG), or at least 128KiB. Once this value has been set, it is difficult to change without recreating the VG, unless no.
9/26/2018 · 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. The man page for vgcreate has a little more detail.
The physical extent (PE) size is the basic unit out of which logical volumes are created. It defines the minimum size of a volume and the possible increments (having a 4MB PE size would mean the minimum volume size is 4MB and you can grow it in 4MB increments).
2/7/2008 · Increase extent size , IMHO it is the better way. vgcreate -s 16 /dev/vg01 /dev/dsk/c8t1d6 (I don’t think that 8 Mo will be enough, but you can try it before using 16 Mo) The disk you are working with has a SAN like instanciation.
