Issue "tac: write error: Broken pipe" during daily plesk upgrade

[floriancourgey]

Hi everyone,

We are using Plesk since mid 2016 to manage 10 websites on our VPS Cloud (OVH as hosting)

It works really good, thank you for providing such product

However, we are experiencing an issue since a few weeks

Everyday we have an alert on a red background which says "Failed to update Plesk. To solve this problem, you can send the update log to Plesk support"

By reading the log, I can tell it's a MySQL update issue

Here's the full output : Plesk 'tac: write error: Broken pipe' issue · GitHub

The interesting part is
'''
Starting xinetd service... already started
tac: write error: Broken pipe
***** problem report *****
===> Plesk database scheme was not upgraded completely. [...]
'''

Do you have any idea ?

Feel free if you need anymore info

Thanks
Florian

Do you have any customizations of your /etc/my.cnf file? Especially lines like:

bind-address = 127.0.0.1

skip_name_resolve

symbolic-links=0

Please comment it if they are exists. Also I'd recommend you try to use official Plesk repositories instead of OVH mirror. Jut move out file /root/.autoinstallerrc and run installer again.

 

[floriancourgey]

I have :
- bind-address is commented
- skip_name_resolve and symbolic-links are not my conf file
- and I remember I added this :
[mysqld]
skip-grant-tables # added on 7 August 2017, see Access denied for user 'admin'@'localhost' - Urgent

I'll try to change the autoinstaller tonight, not to disturb our users during maintenance

 

[floriancourgey]

Hi Igor,

it's not working neither with the CLI, here's what I did :
# mv /root/.autoinstallerrc /root/.autoinstallerrc.bak-ovh
# plesk installer
options : go forward, go forward, go forward (all default)..

You can find the output here : Plesk 'tac: write error: Broken pipe' issue · GitHub

Thank you
Florian

Something wrong with database upgrade:

===> Plesk database scheme upgrade has been started.
Applying migrations from: /opt/psa/bootstrapper/pp17.5.3-bootstrapper/migrations/
Migration failed: 17.5.0/2016-12-26-09-56-48_change_dates_default_value.php
Query failed: UPDATE `APSCatalogUpdates` SET `received` = '1970-01-01 00:00:00' WHERE `received` = '0000-00-00 00:00:00'
Incorrect datetime value: '0000-00-00 00:00:00' for column 'received' at row 1

Try to run

# plesk repair db

before upgrade.
On my test Plesk 17.5.3 server I see:

I did a plesk repair db, it updated 13 tables with datetime 0000-00... to 1970-... without any problem

But when I rerun plesk installer, it hangs at

Checking if update is needed.
This installation of MySQL is already upgraded to 5.7.20, use --force if you still need to run mysql_upgrade

same if I do

apt update

or

dpkg --configure -a

I wanted to do a full backup + full purge + clean install + restore backup of mysql (Upgrading to MySQL 5.7.15 crashes on Ubuntu 16.04) but I am unable to do so because plesk requires mysql server (

apt remove

fails).

Do you have any idea ?

Thanks

 

[IgorG]

Do you have any errors/problems when you run command

# mysql_upgrade -uadmin -p`cat /etc/psa/.psa.shadow`

?

Do you have any idea ?
Thank you

I can only recommend creating a request to support team to do the in-depth investigation to find the reason and to fix it. Please create a ticket to support at Plesk Help Center
