Not work MySQL backup

1. offizieller Beitrag

    Hello.
    I have OMV 3.0.86 and installed MySQL plugin.
    SQL work fine but I have a problem with backup database.
    When I press "Backup" nothing happens.


    When I create "Scheduled backup" and try to run it I have this error:


    I have similar or better to say same issue in 3.0.88


    Code
    Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; export SHELL=/bin/sh; sudo --shell --non-interactive --user=root -- omv-rpc MySql dumpDatabaseToSharedFolder '{"uuid":"dedfa955-c9e0-4231-aed1-a8b697ee9f8d"}' 2>&1' with exit code '1': {"response":null,"error":{"code":0,"message":"Failed to execute command 'export PATH=\/bin:\/sbin:\/usr\/bin:\/usr\/sbin:\/usr\/local\/bin:\/usr\/local\/sbin; export LANG=C; mysqldump --defaults-extra-file='\/etc\/openmediavault\/mysqldump.cnf' --all-databases --result-file=\/srv\/dev-disk-by-label-omv-backup\/mysql\/mysql-2017-10-22T21:34:56+0200.sql' with exit code '1': ","trace":"exception 'OMV\\ExecException' with message 'Failed to execute command 'export PATH=\/bin:\/sbin:\/usr\/bin:\/usr\/sbin:\/usr\/local\/bin:\/usr\/local\/sbin; export LANG=C; mysqldump --defaults-extra-file='\/etc\/openmediavault\/mysqldump.cnf' --all-databases --result-file=\/srv\/dev-disk-by-label-omv-backup\/mysql\/mysql-2017-10-22T21:34:56+0200.sql' with exit code '1': ' in \/usr\/share\/php\/openmediavault\/system\/process.inc:175\nStack trace:\n#0 \/usr\/share\/openmediavault\/engined\/rpc\/mysql.inc(284): OMV\\System\\Process->execute()\n#1 \/usr\/share\/openmediavault\/engined\/rpc\/mysql.inc(175): OMV\\Engined\\Rpc\\MySql->dumpDatabase('\/srv\/dev-disk-b...', '\/etc\/openmediav...')\n#2 [internal function]: OMV\\Engined\\Rpc\\MySql->dumpDatabaseToSharedFolder(Array, Array)\n#3 \/usr\/share\/php\/openmediavault\/rpc\/serviceabstract.inc(124): call_user_func_array(Array, Array)\n#4 \/usr\/share\/php\/openmediavault\/rpc\/rpc.inc(86): OMV\\Rpc\\ServiceAbstract->callMethod('dumpDatabaseToS...', Array, Array)\n#5 \/usr\/sbin\/omv-engined(536): OMV\\Rpc\\Rpc::call('MySql', 'dumpDatabaseToS...', Array, Array, 1)\n#6 {main}"}}


    I'm not an expert but probably problem is with generated command


    Code
    omv-rpc MySql dumpDatabaseToSharedFolder '{"uuid":"dedfa955-c9e0-4231-aed1-a8b697ee9f8d"}'

    I've checked /dev/disk/by-uuid and I don't have link with this uuid



    Code

    I've checked /dev/disk/by-uuid and I don't have link with this uuid

    That is the uuid of the shared folder in the database not the disk uuid.


    What is the output of:

    That is a temporary file created by the code - https://github.com/OpenMediaVa…ngined/rpc/mysql.inc#L242


    No idea why that is failing on your system.

    Have you reset the mysql password from the mysql plugin? It creates the file that is missing.

    Did it many times because I had problem with phpmyadmin, and as you can see it wasn't there.
    But I did it again and voila it is in right place and backup is running fine :D

    I had this same problem.


    I originally created the mysql (from memory: outside of omv) for openkm in omv 2.x which has since been upgraded to 3.x.
    I recently used the plugin schedule backup job, instead of the async i had previously been running.

    Solved my problem - i think....but i am getting this message "stdin: is not a tty" in the email sent to me

    My MYSQL backup call returns just NULL.

    Code
    root@openmediavault:~# omv-rpc MySql dumpDatabaseToSharedFolder '{"uuid":"b761ad8c-140e-4136-80fc-8f76cfabf573"}'
null
root@openmediavault:~#

    Whats wrong here?

    i've als get a lot of errors by mail. Don't know hoe to fix these errors and making a schedule backup. This is an example of one of my mails.

    im getting this error too

    So, I tried deleting the mysql plugin backup schedule and made a new weekly one.
    I then went to the "scheduled jobs" and tried to run the weekly job that was created manually. I got the following error

    in my cron daemon notifications, i get the following error

    seems to be a long time running this error. i
