Cleanup Stale CVS Snapshots

August 30, 2022

Here’s the script that looks mounts with stale file handles and removes them.

#!/bin/bash
file='/tmp/stale.txt'
df -h | grep Stale > $file
sed -i -e 's/df: ‘/'""'/g' $file
sed -i -e 's/’: Stale file handle/'""'/g' $file
while IFS= read -r line; do
  echo 'unmounting '$line
  umount $line
done < $file

How to unmount CVS snapshot volumes all at once using a Bash script. I ran into a scenario where I had to unmount 115 volumes. Instead of manually running umount on each one, I use the script below to unmount all 115 volumes. The script performs a grep for ‘.snapshot’ and then writes the results to a file. I then read the file line by line and perform unmount on each one.

#!/bin/bash
file='/tmp/snapshots.txt'
df -h | grep .snapshot | awk '{print $6}' > $file
while IFS= read -r line; do
  echo 'unmounting '$line
  umount $line
done < $file
