Issue while migrating to MonetDB v11.33.3 (Apr 2019)
All, We are migrating our MonetDB database from MonetDB v11.27.13 (Jul2017-SP4) to MonetDB v11.33.3 (Apr 2019). We tried to bring up the DB instance with MonetDB v11.33.3 (Apr 2019), but getting below error though the same when we tried with previous version MonetDB v11.31.13 (Aug2018-SP2) it worked. Could you help us to identify the issue? 2019-07-24 04:00:21 ERR TSV_PROD_DB_T[88767]: #main thread:!ERROR: BBPcheckbats: cannot stat file /monet_data01/DBFARM_TSV_TEST/TSV_PROD_DB_T/bat/10/45/104502.tail 2019-07-24 04:00:21 ERR TSV_PROD_DB_T[88767]: #main thread:!OS: No such file or directory 2019-07-24 04:00:21 ERR TSV_PROD_DB_T[88767]: !FATAL: BBPinit: BBPcheckbats failed 2019-07-24 04:00:21 MSG TSV_PROD_DB_T[88767]: !ERROR: BBPcheckbats: cannot stat file /monet_data01/DBFARM_TSV_TEST/TSV_PROD_DB_T/bat/10/45/104502.tail 2019-07-24 04:00:21 MSG TSV_PROD_DB_T[88767]: !OS: No such file or directory 2019-07-24 04:00:23 MSG merovingian[88722]: database 'TSV_PROD_DB_T' (88767) has exited with exit status 1 2019-07-24 04:00:24 ERR control[88722]: (local): failed to fork mserver: database 'TSV_PROD_DB_T' appears to shut itself down after starting, check monetdbd's logfile (merovingian.log) for possible hints 2019-07-24 04:02:18 MSG control[88722]: (local): served status list Regards, Sreejith
The function BBPcheckbats that is failing is a new function in the Apr2019 (11.33.3) release. It check during startup of the server that all files that are supposed to be there actually are there. This is apparently not the case in your database. This means your database is corrupt. The reason that older versions start up is that they didn't do this check. But the database is still corrupt. If you issue a query that touches this particular column, the server might crash or at least give an unexpected error. If you're lucky, you can repair the database by creating the missing file and making sure it's large enough. It's anyone guess as to what should be in that file, though.
