PreFreeze and PostThaw linux script problem

[mark14]

Hello,

I have problem with linux scripts. I setup

https://ibb.co/mJkpcgb

But I got error:
https://ibb.co/1b9hRGb

pre-freeze script finished execution with exit code -1
post-thaw script finished execution with exit code -1


As you can see scripts executed successfully on machine with exit code 0 which means everything is ok

It is simply mysqldump script from:
https://bp.veeam.expert/applications/mysql (Database Online Dump During Backup Operations).

Hi,

Would you add some additional debugging lines into the script for troubleshooting purposes, please? Those lines should simply "echo" at what step the script is currently in to some local file on the target machine so you can check at what line it fails. Also, as far as I can see, the script is piping mysqldump output to logger:

Code: Select all

echo "$0 : error, no mysql authentication method set" | logger

That is, you might want to check there as well.

Thanks!

As I said before, script execution has been successed.

Code: Select all

Dec  6 14:21:33 acco-server root: ./backup2.sh executing mysqldump
Dec  6 14:21:33 acco-server root: ./backup2.sh : mysqldump suceeded

And of course mysql dump has been created in /tmp

Code: Select all

root@server:/tmp# du -hsc *
18M     mysql_dump.sql

Weirder thing is that when I create very simply script:

Code: Select all

#!/bin/sh
touch /root/testfile.txt
exit 0

I also get the same error exit code -1

P.S
Syslog file after running job:

Code: Select all

Well, the syslog that you've posted does not seem to be related to the script, those are kernel logs. You should search for 'mysql' keyword instead. Reagrding the simple script returning '-1' - please check whether the credentials that you use to process the VM are sufficient.

Thanks!
