This is a corosync split brain, the mysql and other services, such as rabbitmq, will be failed as a result of the split brain as well.
As a result of yet unknown RC, your corosync cluster had been split into two pieces:
1st partition with quorum (DC node-58)
root@node-92:~# crm status
..Current DC: node-58.domain.tld (2) - partition with quorum
root@node-58:~# crm status
...Current DC: node-58.domain.tld (2) - partition with quorum
And a 2nd partition that thinks it has a quorum with DC node-53
root@node-53:~# crm status
...Current DC: node-53.domain.tld (1) - partition with quorum
