Question SCO osr5's logical volume starting
Hi
My query is regarding the logical volume start. I am using sco open server 5.0.7. I create 3 volumes
1. / 5000 Mb
2. /home -2000Mb
3. /sundeep -500MB

The document of SCO says that the logcal drive start from the 1st block of fs. From the disk label when i jump to the start of the partitions .I found the superblock about 273106 sectors(133mb) away the stating location og partition. The same thing happens in all the partitions.
Why this happens. I tried several times and make different size of partitions.Even i make 100mb partitions but the locations of superblock structure found after the 273106 sectors.(very amazing)

Again i tried on different system with different Hard disk(SCSI) but next time i found the super block position after the 16065 sectors from the starting of partion.

How i found this value and in which structure this value is defined.

Plesae guide me

lvremove

LVREMOVE(8)						      System Manager's Manual						       LVREMOVE(8)

NAME

       lvremove - remove a logical volume

SYNOPSIS

       lvremove [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] [-t|--test] [-v|--verbose] LogicalVolumePath [LogicalVolumePath...]

DESCRIPTION

       lvremove  removes  one  or  more  logical  volumes.   Confirmation will be requested before deactivating any active logical volume prior to
       removal.  Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted  filesystem).   Removing	an
       origin logical volume will also remove all dependent snapshots.

       If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com-
       mand issued from one node can do this.

OPTIONS

       See lvm(8) for common options.

       -f, --force
	      Remove active logical volumes without confirmation.

EXAMPLES

       Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation:

	    lvremove -f vg00/lvol1

       Remove all logical volumes in volume group vg00:

	    lvremove vg00
