I have a large mariadb instance running (400 gb or so).
Due to running out of storage space it crashed.
I went ahead and resized my volume (I am using AWS), and went to restart the service
service mysql start
It did not however start.
journalctl -xe returns the error "2017-07-25 14:19:33 140139278653632 [Note] InnoDB: Waiting for rollback of recovered transactionsto exit"
My assumption is that a transaction was executing, mariadb ran out of space and crashed. It is now trying to rollback that pending transaction and has yet to complete.
I am not particularly experienced with database administration, and I do not want to start messing around in a manner which could potentially corrupt my data.
I was wondering if anyone could share any insight on the appropriate way to discern if my assumption is correct, and how I can most appropriately resolve the situation?
