CentOS 7 / VM Pro server mariadb has crashed and won't restart. Server has about 120 database sites. Been have trouble last few days, but this is the first time it wouldn't start back up.
Can anyone offer immediate assistance?
Crisis has been averted. Somehow the majority of the database's owner group was missing. After going though them all one by one and resetting the group, mariadb started right up. Weird, how on earth did those owner groups go missing.
