LOTS of good stuff everyone! I love collaberation.
OK, so here is what I have come up with...
Whipped together the following scripts; they are still works in progress, so don't judge to harshly. I do have RSA keypairs set up between the machine that I run all my scripts from and all my ESX hosts, so the logins are not interactive.
snapreport[/b]
#!/bin/bash
#
#
#
#
\# Let's start off by setting the 'server1' variable to a name that isn't valid
server1=defaultserver
\# I like to offer the user some information about what they are doing
echo "This script will check for the presence of snapshots on SAN volumes."
echo "This will take a few moments, please be patient."
\# OK, now we will actually do something. Let's call the 'snapcheck' script and put the output in a file to be manipulated.
./snapcheck > snapcheckoutput
\# The output of the above step is pretty ugly, and contains plenty of extra information, we are only interested in the server name. Let's do something about this.
cat snapcheckoutput | grep vmfs | awk -F / '\{print $5}' > snapshotstmp1
\# Since the 'snapcheck' script runs on multiple machines, and some share common SAN volumes, as well as the fact that a server with more than one vmdk file will result in multiple entries, we'll now work on making a list with a single entry for each server.
#Sort the (somewhat) cleaned up file; we want multiple entries of a single server name to show up next to each other.
sort snapshotstmp1 > snapshotstmp2
\# Clean out the file that contains the final product.
cat /dev/null > snapshots
\# I love loops. This one compare each line to the previous, only passing the server name to the final report file when they are different.
for server in `cat snapshotstmp2`
do
server2=$server
if \[ $server1 != $server2 ]
then
echo $server2 >> snapshots
server1=$server2
fi
server1=$server2
done
\# Clean up temporary files, yo.
rm -f snapshotstmp1
rm -f snapshotstmp2
rm -f snapcheckoutput
\# Offer the server list to the user...
cat snapshots
\# ... and let them know they can look at the report any time down the road.
echo "You can view these results later by looking at the \"snapshots\" file"
exit 0
snapcheck[/b]
#!/bin/bash
#
#
#
\# This script runs through our universal servers file and looks for the existence of 'delta' files. This script is called by other scripts.
for server in `cat servers`
do
echo "Checking for the presence of snapshots on $server"
ssh $server "find /vmfs/volumes/ -name '*delta.vmdk'"
done
exit 0
I put plenty of comments in the scripts. If anyone has any questions, I'd be happy to elaborate.
