My mysql Database Directory size is full. So I want to change it to another partition where there is large amount of space. The database version am using is MySQL 5.7.23 and OS is CentOS 7.
After searching internet i got 2 solutions. First one as follows:
Firstly,I created a Systemlink pointing to the new drive. Then I tried to start mysql, it fails everytime when I try to start. On removing systemlink it will start.
The error am getting is
[Note] InnoDB: Highest supported file format is Barracuda. 2018-08-21T10:08:04.839330Z 0 [ERROR] InnoDB: Operating system error number 13 in a file operation. 2018-08-21T10:08:04.839349Z 0 [ERROR] InnoDB: The error means mysqld does not have the access rights to the directory. 2018-08-21T10:08:04.839360Z 0 [ERROR] InnoDB: os_file_readdir_next_file() returned -1 in directory ./, crash recovery may have failed for some .ibd files! 2018-08-21T10:08:04.839385Z 0 [ERROR] InnoDB: Plugin initialization aborted with error Generic error 2018-08-21T10:08:05.440529Z 0 [ERROR] Plugin 'InnoDB' init function returned error. 2018-08-21T10:08:05.440597Z 0 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 2018-08-21T10:08:05.440610Z 0 [ERROR] Failed to initialize builtin plugins. 2018-08-21T10:08:05.440617Z 0 [ERROR] Aborting 2018-08-21T10:08:05.440665Z 0 [Note] Binlog end 2018-08-21T10:08:05.440770Z 0 [Note] Shutting down plugin 'CSV' 2018-08-21T10:08:05.441349Z 0 [Note] /usr/sbin/mysqld: Shutdown complete
Secondly, https://www.digitalocean.com/community/tutorials/how-to-move-a-mysql-data-directory-to-a-new-location-on-ubuntu-16-04 I followed this url and after that when tried to start mysql keep on getting this error Cant connect to localhost (111) (Error: 2003). This time nothing is showing in mysqld.log file
