Exports Cleanup

[Andrew Stack]

Hello,

I'm wondering if anyone has figured out a way to delete a single host from several random exports at once?  Say you have 100 exports and you decommission a host that is exported to 50 of the 100.

Currently, I'd find the export ID: 

isi nfs export list -v | grep 'Export\|sonasdm03'

Export 10: 

           host sonasdm03

Export 12: 

           host sonasdm03

Export 13: 

           host sonasdm03

Then I'd delete it as below....

Example:

nas-rwc-is4-40# isi nfs exports modify -i 11 --delete-client=sonasdm03

Warning (export still modified): bad hostname sonasdm03

nas-rwc-is4-40# isi nfs exports modify -i 12 --delete-client=sonasdm03

Warning (export still modified): bad hostname sonasdm03

nas-rwc-is4-40# isi nfs exports modify -i 13 --delete-client=sonasdm03

Warning (export still modified): bad hostname sonasdm03

like watching paint dry but somehow worse...

Anyways, just curious is anyone has scripted a process to alleviate the tedium...if so please share.  

Thanks in advance.

I'm wondering if anyone has figured out a way to delete a single host from several random exports at once?  Say you have 100 exports and you decommission a host that is exported to 50 of the 100.

 

You could do something like:

#!/bin/bash

if [[ $1 == "" ]]; then
   echo
   echo "usage $0 [hostname to remove]"
   echo
   exit 99
fi

# look at 'nfs exports list' output.  Grab the lines that start
# with numbers.  These are the rule identifiers.

for rule in $(isi nfs exports list |egrep '^ *[1-9]'|awk '{print $1}')
do
 isi nfs exports list -i $rule -v  |grep $1 >/dev/null >1
 if [[ $? == 0 ]]; then
    echo "isi nfs exports modify -i $rule --delete-client=$1"
 fi

done

 

...

Run it like so:

 

mbisilon-1# ./remove-host-from-share.sh helium.multicare.org

isi nfs exports modify -i 7 --delete-client=helium.multicare.org
isi nfs exports modify -i 8 --delete-client=helium.multicare.org

 

I left the delete commands echoed out.  This would work for my environment but obviously would want to understand & test in your environment.

Hi Andrew, we can script it. Let me find some free time. Trinh

Hi Scott,

I have modify your script into this.  I commented out the execution line.

for rule in $(isi nfs exports list |egrep '^ *[1-9]'|awk '{print $1}')
do

 for host in $(isi nfs exports list -i $rule -r -v  | tr '\[' '\n' | grep ^host | cut -d\] -f1 | awk -F ' ' '{print $2}')
   do
      echo -e "\tBad hostname $host found."
      #Run an nslookup on that hostname to make sure it doesn't return an ip address
      #return 0 if selected lines are found, in this case no ip found result is not 0
      nslookup $host | grep Add | grep -v "#"
      if [[ $? != 0 ]]; then
           echo -e "\tNSLOOKUP on $host failed, $host have no IP"
           echo "Removing client $host from export number $rule"
           #isi nfs exports modify -i $rule --delete-client=$host
      fi
   done
done
