Reproduced this problem. Steps to reproduce: 1. Load a cluster with over 100M of data 2. Go into ndb_2_fs/LCP/x/ (where x is the last LCP) 3. shell> truncate --size 10000000 T2F0.Data (assuming that is the table) 4. Start cluster *bang*

Description: This happens sometimes when restarting a node. Further attempts to restart it also fails. Status: Temporary error, restart node Message: Internal program error (failed ndbrequire) (Internal error, programming error or missing error message, please report a bug) Error: 2341 Error data: restore.cpp Error object: RESTORE (Line: 490) 0x0000000a Program: ndbd Pid: 28138 Trace: /mysql/ndbd/data/ndb_3_trace.log.3 Version: mysql-5.1.37 ndb-6.3.27a-GA from restore.cpp Restore::restore_next(Signal* signal, FilePtr file_ptr) { . . . if(4 * len > left) { /** * Not enought bytes to read "record" */ ndbout_c("records: %d len: %x left: %d", status & File::READING_RECORDS, 4*len, left); if (unlikely((status & File:: FILE_THREAD_RUNNING) == 0)) { ndbrequire(false); // line 490 in 6.3.27a } len= 0; break; } How to repeat: stop node 1 stop node 2 start node 2 start node 1 But it doesn't happen always, not even often. Got logs. Suggested fix: A more verbose error message might be a start. Doesn't appear to be a temporary error.
