LVM Snapshot script

stacksofplates

So I noticed an issue, I figured I'd post it in case anyone else has the same problem.

I created a bash script on a CentOS 7 server to do some LVM snapshots and then export them to .gzip files. If I put the script under /etc/cron.daily it worked fine, however if I added the script in crontab as root or sudo, the script would run, but would give the error command not found for lvcreate and lvremove.

I just had to add this to the script:

PATH=/usr/sbin:/usr/bin:/sbin:/bin

and it works fine now.

Best practice, which almost no one follows, is to use explicit paths in scripts rather than implicit. then you don't need that at all.

I guess that makes 100% sense since you have to start the script with an absolute path ha.
