script to display unavailable/stale lv's in vgdisplay -v output

[Mike Kapsak]

Can someone provide a script that will report on unavailable/stale logical volumes in a vgdisplay -v command and display the system name, the LV Name, and the LV Status on one line.

Thank you

Hi

vgdisplay -v /dev/vg0x | grep -i stale

Heres the structure, fill in the blanks,...

vgdisplay -v |awk '$0 ~ /LV Name/ {lv=$3} $0 ~ /LV Status/ {print lv" "$4}' >/tmp/file1

while read lv status
do

COUNT=`lvdisplay -v /dev/vgNAME/$lv |grep stale |wc -l`

print $lv" "$COUNT" "$status

done
The read statement may need tuning or correcting.

Share and Enjoy! Ian

vgdisplay -v | grep stale

I wrote a script that does more than that. Invoke ..
# ./lvmstat
for full usage. You may find it useful. Open it with wordpad.

Being that you haven't really explained why the answers provided aren't what you expected, then how about something like this:


vgdisplay -v | grep -i -e stale -e "LV NAME"


live free or die

I appreciate everyone's response to my question. I asked because I am not fluent in scripting. S.K. supplied a nice script, but what I'm really looking for is a simple report that contains, line by line, the system name, VG Name, VG Status, LV Name, and LV Status, distribute this script to all servers and put it in cron. With that info I want to be able to mail and/or page interested parties.

Thanks

scope creep. Now that we have a clearer statement of the problem, and you seem to have an answer, do you still need help??

Mike,

Being non-fluent (is that affluent?) in scripting myself, I'll just throw in a suggestion. How about a script that greps the vgdisplay output for stale (or any other "bad" state) and, if found, emails whomever a brief message to check machine fubar's lvol status because something's amiss?

Is that more what you had in mind?

In the future I will try to elaborate on my question. I appreciate the quick responses each time I post a message. Again thanks for helping me.

Hi Mike:

Crude and quick:

#!/usr/bin/sh
vgdisplay -v| awk -v HOST=$(hostname) '/VG Name/ {VG=$3}
/VG Status/ {VSTA=$3}
/LV Name/ {LV=$3}
/LV Status/ {LSTA=$3;print HOST,VG,VSTA,LV,LSTA}
'
exit 0

Regards!

A simple much one ..

#! /usr/bin/ksh
#
HOST=$(hostname)

print "$HOST\n"
for vg in $(vgdisplay|grep -E 'VG Name'|awk '{print $3}')
do
print "$vg\n"
VGSTAT=$(vgdisplay $vg|grep -E 'VG Status')
print "$VGSTAT\n"
LVSTAT=$(vgdisplay -v $vg|sed 's/^[ \t]*//'|grep -E 'LV Name|LV Status')
print "$LVSTAT\n"
done

Hi Mike


here is one script which will help you .

Pete,

You're summation is correct, but i don't know how to script it. The report would look like this and only report unavailable or stale, put it into cron at a given time, and mail anyone who wants it.

"System Name"
VGName VGStatus LVName LVStatus

Okay, Mike - you asked for it. Here's my attempt at a script. Maybe someone will see the simple approach we're attempting to take here and polish it for you, but I think this is the basic idea:


if [ `vgdisplay -v |grep -i stale | wc -l` -gt 0 ]
then
echo "Server $hostname has an LVM issue" > file.oops
elm -s "Oops" joeblow@wherever.com < file.oops
fi


Good Luck,

Pete

[Mike Kapsak]

Pete,

The script looks simple enough. Now I need to work on making a volume stale in order to test.

Thank you,

Hi Mike

There is a script available called lvmcollect that gives you a full overview of your lvm system

Mike,

For my own testing purposes, I grepped for "syncd" rather than stale. There's a lot of "syncd" lvols out there.
