missing "SAVE" button about ovirt_simple_backup

[zipurman]

Save button should be at the bottom of the settings page? If not, please send a screenshot of the entire page so I can see where the error is occurring.

[txsastre]

hi ! yes I've seen the snapshots you have deployed on the docs.

in my situation at the bottom I don't see the "save" button, tested on a firefox 58 and 59, and also with a iexplorer.

also checked the code and I see and the end of it the the code about this button.

as I cannot capture the hole screen, I've done 3 snapshots, there's no button :/

[zipurman]

Looks like it is stopping at the Storage Domains. What Storage domains do you have in your oVirt setup?

You could also run the following on the BackupVM:

tail /var/log/apache2/error.log -f

Then refresh your browser on the settings page of the script to see what errors come up in the console.

Then just let me know.

[txsastre]

Hi !
I have 3 storage domains, 1 was created at installation time "ovirt-manage-repository" the other 2 are for VM and ISO

[txsastre]

and the error seems related to a missing variable.

[zipurman]

The config.php must be missing. New version will catch this.

[txsastre]

no, there it is. :/

ok, don't worry, I will wait to the new version :D

[txsastre]

version 0.6.0. same error

looks that there's some problem when looking the Clusters "ovirt_rest_api_call('GET', 'clusters/')" at the end.

[zipurman]

The code is expecting to get xml from the api and it isnt. I will asdd a try/catch block in there ut I am thinking its another issue with authentication.

[txsastre]

Ok. Thanks.
meanwhile I am going to install a new backup apliance from scratch.

[zipurman]

I have updated the code. Simple fix as some of your (auto generated) files were still old version.

I would recommend that you delete any files in your /var/www/html/cache/ directory when upgrading. I will code that in asap so that is no longer a user issue.

I would do the following after that, go to the settings page, enter in as much info as possible including user/pass. Then ** go to the engine VM and enter "ovirt-aaa-jdbc-tool user unlock admin" to make sure the admin user hasnt been locked by too many failed api queries. Then click SAVE on the sttings page. Then choose your Domain and Cluster and click SAVE again. Hope that works!

[zipurman]

BTW, apache error log will complain sometimes due to the outputs of fdisk queries. I havent been able to silence that as its usually related to dynamic devices and www-data doesnt have access by default. Those errors can be ignored as they dont really create an issue.

[txsastre]

still cannot do the "save" option because web stops at "Default restore options"

but as I told previously I will try a new installation from scratch.

[zipurman]

Try deleting your config.php file

[txsastre]

deleted everything and uploaded again.
on ovirt-engine executed ovirt-aaa-jdbc-tool user unlock admin

WebUI is OK, but the settings web still stops at "Default Restore Options"

[txsastre]

OK, I've done the BackupEngine VM from scratch, still having the same issue.
Well now I cannot see the button in the oVirt interface, but I go directly to the BackupEngine web, and the same issue appears.

beginning to think that the problem is in the ovirt-engine, because I am also testing this other project vacosta94/VirtBKP#2 (comment) and also having similar issues

[zipurman]

If you can see the save button now, try this.

1. Go to the settings page a fill in all the fields (DONT CLICK SAVE YET)
2. Go to the command line on the engine VM and do a "ovirt-aaa-jdbc-tool user unlock admin"
3. Now click SAVE on the settings page.
4. Hopefully you now see the domains and the Cluster dropdowns with some options in them. If you do, choose the options for those 2 and SAVE again.

If that doesnt work, let me know exactly what you are seeing in the logs for errors.

You could also try this in your browser to see if it helps find the problem,
goto:
https://YOUR-IP-OF-ENGINEVM/api/clusters/

Then view the source of that page which should have the XML from the API, if not, then your problem is on the Engine.

[txsastre]

hi!, thanks for your support.

I cannot see the SAVE button, so I tested the url of the api
I think it works because I receive this code

[zipurman]

Are you using Debian or CentOS/RH as your OS for the Backup Appliance VM?

If using CentOS/RH, try this:

yum install php-libxml php-xml php-simplexml

[txsastre]

No. I'm using Debian 9
Should I try with CentOS?

[zipurman]

Try:

apt-get install libapache2-mod-php5

[txsastre]

I will try tomorrow but I'm Debian 9 is using php7, guess is the same.

[zipurman]

I havent tested with php7 yet. This should work:

apt-get install php7.0-xml
service apache2 restart

[zipurman]

Also, make sure you have this installed:

apt-get install php7.0-curl
service apache2 restart

[txsastre]

hi there, with apt-get install php7.0-xml now it works. although I can see all the web plus the "SAVE" button. :D

Now I'm going to test the setting, if something is wrong I will open another issue.

Thanks !
