[linux-lvm] Bug report for LVM 1.08

[Alexander Danoyan]

Hello Heinz,

Here are a few defects.
There are inconsistency in view between 
lvdisplay and lvdisplay with -c option
Here is an example:

lvdisplay /dev/vg_demo/striped 

--- Logical volume ---
LV Name                /dev/vg_demo/striped
VG Name                vg_demo
LV Write Access        read/write
LV Status              available
LV #                   3
# open                 0
LV Size                1 GB
Current LE             32
Allocated LE           32
Stripes                2
Stripe size (KByte)    4
Allocation             next free
Read ahead sectors     1024
Block device           58:2

lvdisplay -c /dev/vg_demo/striped 
/dev/vg_demo/striped:vg_demo:3:1:2:0:2097152:32:32:0:1024:58:2

1. As you can see the option -c does not show information about stripes
at all.
2. -c option also does not show information on snapshot volumes

3. Also in vgdisplay, pvdisplay and lvdisplay with -c option some of
the sizes shown in KBytes and some of the sizes in the number of sectors
? 

We are (here at Novell) relying heavily on -c option. 
Do you have any plans to fix these defects ? 
If yes when are you planing to have a patch or next release ?
Thanks a lot.

Alex.

Alexander,

the colon output has been added in 1997 to address a SuSE requirement
IRT to easing the installation process and displays the requested fields.

LVM1 is in feature freeze for a long time now in favour
of putting the development focus on LVM2, which is compatible to LVM1.

Please check into the pvs, vgs and lvs commands in LVM2,
which provide formatable output.

Regards,
Heinz    -- The LVM Guy --

*** Software bugs are stupid.
    Nevertheless it needs not so stupid people to solve them ***
