MySQL NDB Cluster 7.2 Release Notes
Restoration of metadata with ndb_restore
-m
occasionally failed with the error message Failed to
create index... when creating a unique index. While
disgnosing this problem, it was found that the internal error
PREPARE_SEIZE_ERROR (a temporary error)
was reported as an unknown error. Now in such cases,
ndb_restore retries the creation of the
unique index, and PREPARE_SEIZE_ERROR is
reported as NDB Error 748 Busy during read of event
table.
