Has Anyone Written a "Suite" of LVM Tools/Scripts Yet

[Alzhy]

I am planning to write an LVM utility that does among others:
.
- list what VG's are there in a system
- list LVOLS within a VG with formatting
- show member PV's within a VG
- Free extents on a VG
- Free extents within a PV
- etc., etc. sort of equivs on commands avail on VxVM.
.
Has anyone doen this already? Instead of reinventing the wheel.. would anyone be kind enough to share their script(s).
.
Graci!

There are many of these floating around:
LVMcollect
Sysinfo (a HP written version and a shareware version)

I have some pieces. The nicest piece I have is disk.status

It checks disks and can be used to display more information if you wish to play with it.

Attaching.

see attached, check all PV status (size, free space), and the assoicate VGs & LVs.

[Hein van den Heuvel · Accepted solution]

I cobbled up the attached little perl script to summarize VG / LV / PV data from vgdisplay. I'll include it here, but you problably should use the attached version as the forum still swallows spaces.

Enjoy,
Hein.

#!/usr/contrib/bin/perl -w
print "Type Name Allocated Total Free\n";
print "---- --------------------------- -------- -------- --------\n";
foreach $_ (`/usr/sbin/vgdisplay -v`) {
if (/^(\s*\w\w) Name\s+(\S+)/) {
$type = $1;
$name = $2;
$name =~ s/\/dev//;
}
$pe = $1 if (/^PE Size \(Mbytes\)\s+(\w+)/);
$alloc = $1 if (/Allo.* PE\s+(\w+)/);
$total = $1 if (/Total PE\s+(\w+)/);
$free = $1 if (/Free PE\s+(\w+)/);
if (/^$/) {
printf ("%-6s%-30s%9d%9d%9d\n",
$type, $name, $pe * $alloc, $pe * $total, $pe * $free);
$name = $type = " ";
$alloc = $total = $free = 0;
}
}

Hein,
.
Exactly what I am looking for!
.
Thanks a whole lot!

Hein,

I get the following using your script:

printf (...) interpreted as function at /usr/local/bin/vgdisplay.pl line 15.

I have a simple one that lists disks by VG, can be modified to list by LV as well.

# cat vglist.sh
for name in `cat /root/vgnames.out `
do
echo $name
vgdisplay -v $name |grep "PV Name" |awk '{ print $3 }'
done > /root/disks.by.VG.`date +%m%d%y` 2> /root/vgerr.`
date +%m%d%y`

Thanks for the feedback. I posted an early version with " -w " warnings requested.
Here is a more recent one, with STRIPES added, and lines with zeroes replaced by blanks.

#!/usr/contrib/bin/perl

print "Type Name Stripes Allocated Total Free\n";
print "---- ------------------------------ -- -------- -------- --------\n";
foreach $_ (`/usr/sbin/vgdisplay -v`) {
if (/^(\s*\w\w) Name\s+(\S+)/) {
$type = $1;
$name = $2;
$name =~ s/\/dev//;
}
$pe = $1 if (/^PE Size \(Mbytes\)\s+(\w+)/);
$alloc = $1 if (/Allo.* PE\s+(\w+)/);
$total = $1 if (/Total PE\s+(\w+)/);
$free = $1 if (/Free PE\s+(\w+)/);
$s = $1 if (/Used PV\s+(\w+)/);
if (/^$/) {
if ($alloc + $total + $free) {
printf ("%-6s%-30s%3s%9d%9d%9d\n",
$type, $name, ($s)?$s :" ", $pe * $alloc, $pe * $total, $pe * $free);
} else { print "\n" } ;
$name = $type = " ";
$alloc = $total = $free = $s = 0;
}
}

This one summarizes just the VG's - called vgttl - uses bdfmegs.

Output:

# vgttl
VG Size(MB) In use Available
vg00 22780 5700 16546
vg01 12288 4 11901
vg30iqa 1311456 1186182 124296
vg31iqa 2048 1028 956
vg32iqa 232688 22685 206161
----- -------------- -------------- --------------

Oh....and here is bdfmegs....

Yes - check out Ralph Roth's (HP engineer) "cfg2html" utility. This does LVM and just about everything else you will need to document a HP server (and is available for other platforms as well).

excuse me guy i think that you can use HATOOLS which have a lot of good script like xvg
