Hi,

I was wondering what the maximum number of LV partitions are for a given PV -and is this configurable ? We have a situation where it would be convenient to have a large number of small partitions and be able to grow those partitions as needed. I just don't know what LVM supports in that area.

there is no relation between LV and PV, the whole idea is to group more
Physical Volumes (i.e. real disks) into a Volume Group, then split the
Volume Group into smaller Logical Volumes.
Btw, these are referred as 'Volumes' not 'partitions'.

as an answer for your second question, the manual page for vgcreate
states that with lvm2 metadata format (the default), has no limit for
the number of LV or PV.

Regards,
L.
