[linux-lvm] wrong data unit in lvdiskplay?

[linux-lvm] wrong data unit in lvdiskplay?

[Ming Zhang]

I am not sure if this is a bug or my stupid error.

I am using lvm-1.0.3-13, which come from Fedora core 1. I created a
lvol1 with size -L 2000M. then

# lvdisplay /dev/vg1/lvol1
--- Logical volume ---
LV Name                /dev/vg1/lvol1
VG Name                vg1
LV Write Access        read/write
LV Status              available
LV #                   1
# open                 0
LV Size                1.95 GB
Current LE             500
Allocated LE           500
Allocation             next free
Read ahead sectors     1024
Block device           58:0

# lvdisplay -c /dev/vg1/lvol1
/dev/vg1/lvol1:vg1:3:1:0:0:4096000:500:500:0:1024:58:0
                                                                                           here i found that its size is 4096000. base on the document of lvdiskplay, this should be in KB unit. so two output from lvdisplay is mismatched. can anybody tell me why?

I don't think this is your error. I'm seeing th same output on my systems and I don't like it. Thanks for pointing this out before I wrote some script to parse the INCORRECT output of lvdisplay -c.

FYI: I checked the redhat bugzilla and couldn't find a mention of this, so I entered this as bug #127858.
