The default PE size of 4MB limits a single logi- cal volume to 256GB (see the -s option to raise that limit). There is also (as of Linux 2.4) a kernel limitation of 2TB per block device. As far as I remember, this limit is also there in LVM1. Hope it helps. -- Jose Luis Domingo Lopez Linux Registered User #189436 Debian Linux Sid (Linux 2.5.68)
