Description:
ndb management node failed to start when ipv6 disabled using kernel parameter.

How to repeat:
add  ipv6.disable=1 in GRUB_CMDLINE_LINUX option in grub.
update grup and reboot server.
Start ndb management node by ndb_mgmd -f /var/lib/mysql-cluster/config.ini

Get the following error

MySQL Cluster Management Server mysql-8.0.28 ndb-8.0.28
2022-02-17 08:39:16 [MgmtSrvr] ERROR    -- At least one hostname in the configuration does not match a local interface. Failed to bind on xxx.xxx.xxx.xxx
2022-02-17 08:39:16 [MgmtSrvr] ERROR    -- The hostname this node should have according to the configuration does not match a local interface. Attempt to bind '192.168.0.71' failed with error: 97 'Address family not supported by protocol'

Hi,

Thanks for the report. I will verify this behavior but I'm not sure we can do much about it but let us see what the ndbcluster team will say. Use --bind-address to only bind to ipv4 for workaround.

thanks

I tried --bind-address command line option. But it failed with same error.

I'm having this problem on version 8.0.31-1ubuntu22.04.  ipv6 is disabled on all my servers.

Documented fix as follows in the NDB 8.0.34 and 8.1.0 changelogs:

    NDB did not start if IPv6 support was not enabled on the host,
    even when no nodes in the cluster used any IPv6 addresses.

Closed.
