Up to 256 PVs per VG and up to 256 LVs system total. Up to 2TB per PV/LV because of the Linux 2.4 block device layer constraint. Eg. create a VG with up to 256PVs, each 2TB in size -> 512TB VG size. That VG can have as many as 256 LV, each max. 2TB in size. You typically have more than 1 VG *and* the max. 256 LVs/system still applies (eg, 2 VGs could have 156 LVs in the first one and up to 100 LVs in the 2nd one). > > Numbers i found on the net found are old (2001/2002) and i > need to deploy solution with several tera byte. If you need more than 2TB/LV, the LVM1 compatible device-mapper/LVM2 in Linux 2.6 is your friend, because 2.6 supports large block devices beyond 2TB. > > Thanks ! > > > > _______________________________________________ > linux-lvm mailing list > linux-lvm@redhat.com > https://www.redhat.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
