Re: NDB data node failed and sent another data node into a crash loop

It seems that Node 18 failed for some reason which isn't clear from the
above. During its restart Node 19 failed in COPY_FRAGREQ. Again would
require more crash log info to understand why this happens.

It seems that somehow Node 18 isn't able to restart using the
local data files.

The best way forward I would suggest is the following:
1) Take a backup with the existing cluster
2) Restart Node 18 using --initial flag, this will restart from scratch and copy data from Node 19 to the starting node.
