Hi`

We are using mysql cluster (8.0.21) as
3 mgm nodes, 2 data nodes (disk storage, 1 shard, 2 replica), 1 mysql node

On this monday, data node master (node id 11) had shutdown with error message "file system error. start initial'.

And I tried "ndbmtd --initial", but same error.
So I replaced with new machine, and tried again.
But, after about 1 hour, following error reported.

------------------------
mgm
------------------------
ndb_mgm> Node 11: Forced node shutdown completed. Occurred during startphase 5. Initiated by signal 6. Caused by error 6000: 'Error OS signal received(Internal error, programming error or missing error message, please report a bug). Temporary error, restart node'.

------------------------
ndb_11_error.log
------------------------
Current byte-offset of file-pointer is: 1067

Status: Temporary error, restart node

***EOM***


Db service is availeable with another data node (node id 12).
What should I do ?
How can I revive data node 11 ?

Should I upgrade to 8.0.22 ?
Or is this any kind of timeout problem ?
