Hi!

I'm to build some storage pool for an in-company network. It
will exceed 1TB in some time, so I'd like to get some proper
information on this *before* I get into trouble:-) So, my
final question is: How big may an LV be?

The FAQ tells me (in Q9) something of 2TB, but lvextend INFOs
me of a maximum of 1TB. Where's the real limit? My understanding
is that limitation is coming from kernel to handle all data
in chunks of 512Bytes. Is the maximum number of 512Byte blocks
per device to be increased in some time?

MfG, JBG

I'm having the same problem as well. gdb on the core file shows

 lv_create (vg=0xb, lv=0xbffffab4,
    lv_name=0xbffffae4
"uuy?\003uy?(uy?Guy?iuy?suy?6?y?U?y?o?y?\204?y?\233?y?|?y?E?y?O?y???y?i?y?u?
y?\nyy?\eyy?)yy?4yy??yy?Eyy?Uyy?") at lv_create_remove.c:42
42      inline int lv_create ( vg_t *vg, lv_t *lv, char *lv_name) {

I haven't changed the inlines yet since it's a production system, and it
didn't seem to help for John
