mysql (mariadb) does not start anymore after Updating to 1.51.0 from 1.50.3

[lockeftw]

Hello There,

i have updated the ncp installation from 1.50.3 to 1.51.0 since then the i get the

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

But i can access the webconfig page. In the Logfile i have found following line:

#40 {main}ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (111)
admin user not found

I also tried a clean restart of the raspi but mysql service doesn't start at all. starting manually leads to:

Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

in var\log\mysql i can't find a file.

In the Logfile of ncp i have found these lines:

Update: i noticed that the execution of some commands a very slow. even the "ls" command needs some seconds to display the content of a folder. The "top" shows that there is only 93MB of Free Memory from avaiable 3.9GB Memory of raspi 4 . Maybe the nc-limits.sh bash tries something strange.

Hello ianme,

i solved this by getting a new ssd drive and intalled the latest image , so i get rid of sd card ( i think it was broken because it says that some BUS can't read by executing the command systemctl status mariadb.service or journalctl -xe). after the new fresh reboot from the ssd i scipped the initialisation and restored the DB-Backup i made daily. Then i changed the Datadir manually to the HDD and it works now.
