Innodb crash recovery - how to tell when it has completed?

[dachan]

Typically after MySQL is started, the applications are then
started. The one situation I’ve run into is when recovery
is being done, which may take some time - the applications will fail to connect and eventually give up & fail to start.

Is there an option to make mysqld (or mysqld_safe script) block, that is not return, until recovery is complete?

OR

Is there a way to tell via the mysql client or utilities
that recovery is in progress?

I’d hate to grep thru the .err file and look for a certain string… There must be a better way!

Thanks

the mysql utility has a --connect_timeout= option

You could try setting this to a large amount, although typically Id prefer to allow it timeout, and handle the failure by retrying later
