Mariadb not starting, possible corruption in database

I have the error mysqld got signal 6 ; where mysqld died. If you see no messages after this, something went
terribly wrong…
stack_bottom = 0x0 thread_stack 0x48000
/usr/libexec/mysqld(my_print_stacktrace+0x3d)[0x56448c023cad]
/usr/libexec/mysqld(handle_fatal_signal+0x515)[0x56448bc37975]

i think i need to restore just the databases, how do i go about completing that task without having to rebuild and restore the complete server.

thanks

Check in the log if this (failed innodb recovery) matches your case:
