[linux-lvm] Is there a maximum for LV?



Hi,

On the past I was using lvm 1.1rc2. For an unknown reason, the version is not anymore available.
But with this version, when I do a "vgdisplay" I was able to saw the LV Max Size:

[moonlight]:/# vgdisplay    
--- Volume group ---
VG Name               vg1 
VG Access             read/write
VG Status             available/resizable
VG #                  1
MAX LV                255
Cur LV                1
Open LV               1
MAX LV Size           1023.97 GB  <----------
Max PV                255
Cur PV                2
Act PV                2
VG Size               254.31 GB
PE Size               16 MB
Total PE              16276
Alloc PE / Size       16276 / 254.31 GB
Free  PE / Size       0 / 0
VG UUID               31iNWK-Ario-C4tq-yQNi-sGVk-gGs0-CjVV7T

How I'm testing LVM2. The field "MAX LV Size" is not there anymore. Is this means that LV doesn't have a maximum?

Output from LVM2:
[neptune]:/u# lvm vgdisplay vg02
  /dev/cdrom: open failed: Read-only file system
  --- Volume group ---
  VG Name               vg02

  Cur LV                1
  Open LV               1
  Max PV                256
  Cur PV                2
  Act PV                2
  VG Size               50.86 GB
  PE Size               4.00 MB
  Total PE              13019
  Alloc PE / Size       13019 / 50.86 GB
  Free  PE / Size       0 / 0   
  VG UUID               Rw0ckX-GCd2-vlyF-KSWf-Q5tg-Qp2u-0Qjc7E


I just want to make sure that my configuration is all set to support very large LV.

Thanks again for your precious help!

Regards!
