Comment 9 for bug 1713778

Manoj:

I ran the two commands on the one container where mysqld had crashed.

ubuntu@juju-6db2c9-0-lxd-5:~$ sudo myisamchk -r -q /var/lib/percona-xtradb-cluster/mysql/db
- check record delete-chain
- recovering (with sort) MyISAM-table '/var/lib/percona-xtradb-cluster/mysql/db'
Data records: 22
- Fixing index 1
- Fixing index 2
ubuntu@juju-6db2c9-0-lxd-5:~$ sudo myisamchk -r -q /var/lib/percona-xtradb-cluster/mysql/user
- check record delete-chain
- recovering (with sort) MyISAM-table '/var/lib/percona-xtradb-cluster/mysql/user'
Data records: 26
- Fixing index 1

Then I stopped and started that container.

THe daemon did not stay up long. It went down pretty soon with this in the error.log:
