1) Is there any api library for retrieve linux lvm configuration? I.e.
querying for all the vg(s), pv(s), lv(s) on the system?
The commands: lvs, pvs, vgs with numerous cmdline flags.
See lib/report/columns.h for field names
liblvm.a seems handy, to generate lvm command line tools, but I'm missing
a clear differentiation between modifying and non modifying usage.
I'm asking, as I want to develop some lvm information system running
as a web service to provide a quick overview about my lvm configuration
and status. Thus I definitely want to run it as non root. I might use
those nice lvs,pvs,vgs commands, but I don't want to provide them with
a suid-bit, as they are potentially able to modify my lvm. The former
/proc interface was ideal for this purpose, but it seems to be missing for
LVM2. Are there any plans, to provide lvm informations via /proc or /sys
again, or would it be possible to write somehow "restricted" lvm-tools
using liblvm?
