Connectivity issue between the extents of a logical volume when extended

Dear Awadhesh,

Basically I am reading my hard disk through Winhex(ver-13.5) and I am unable to make the connectivity between the extents of a logical volume within a volume group. As in my last query I have told that I have made a Logical Volume Group of 50GB, in which I have created 2 logical volumes(LogVol01 and LogVol02), both of 10 GB. After some time the disk space allocated for first logical volume(i.e. 10GB) gets filled, then I further extended this logical volume by 10GB. Now the total disk spcae allocated to my first logical volume is 20GB. So now, if you check it through WinHex first it keeps 10GB of first logical volume, then 10GB of second logical volume and then again 10GB of first logical volume, which I have extended later. Now my question is where exactly it keeps this information that from which particular sector or offset it will keep its extent. As i have to make a connectivity between the first 10GB of first logical volume and its extent which is also of 10GB that I got after the second logical volume. Now I think I have made my point more clear to you.
Ask to me if there is any confusion yet.

Regards
Himanshu

NAME
lvdisplay - display attributes of a logical volume SYNOPSIS
lvdisplay [-a|--all] [-c|--colon] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--maps] [--nosuffix] [-P|--partial] [--units hHbB- sSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]] lvdisplay --columns | -C [--aligned] [-a|--all] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--noheadings] [--nosuffix] [-o|--options [+]Field[,Field]] [-O|--sort [+|-]Key1[,[+|-]Key2[,...]]] [-P|--partial] [--segments] [--separator Separator] [--unbuffered] [--units hHbBsSkKmMgGtTpPeE] [-v|--verbose] [--version] [LogicalVolumePath [LogicalVolumePath...]] DESCRIPTION
lvdisplay allows you to see the attributes of a logical volume like size, read/write status, snapshot information etc. lvs (8) is an alternative that provides the same information in the style of ps (1). lvs is recommended over lvdisplay. OPTIONS
See lvm for common options and lvs for options given with --columns. --all Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as mirrors, but which are not independently accessible (e.g. not mountable). For example, after creating a mirror using 'lvcreate -m1 --mirrorlog disk', this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog. -c, --colon Generate colon separated output for easier parsing in scripts or programs. N.B. lvs (8) provides considerably more control over the output. The values are: * logical volume name * volume group name * logical volume access * logical volume status * internal logical volume number * open count of logical volume * logical volume size in sectors * current logical extents associated to logical volume * allocated logical extents of logical volume * allocation policy of logical volume * read ahead sectors of logical volume * major device number of logical volume * minor device number of logical volume -m, --maps Display the mapping of logical extents to physical volumes and physical extents. To map physical extents to logical extents use pvs --segments -o+lv_name,seg_start_pe,segtype. --columns | -C Display output in columns, the equivalent of lvs. Options listed are the same as options given in lvs (8). Examples "lvdisplay -v /dev/vg00/lvol2" shows attributes of that logical volume. If snapshot logical volumes have been created for this original logical volume, this command shows a list of all snapshot logical volumes and their status (active or inactive) as well. "lvdisplay /dev/vg00/snapshot" shows the attributes of this snapshot logical volume and also which original logical volume it is associated with. SEE ALSO
