[Maria-discuss] Issues cross-compiling MariaDB for ARM
by Hamish MB 01 Jul '19

01 Jul '19

Hi all, I've been having some issues attempting to cross compile MariaDB 10.4.6 for ARMv5. I always get to a certain point, and it tries to compile storage/mroonga/vendor/groonga/lib/CMakeFiles/libgroonga.dir/ts/ts_util.c.o. This hangs for a long time, and eventually I get two notes about the variable size tracking limit being exceeded, and then the build fails with no clear explanation: [ 38%] Building C object storage/mroonga/vendor/groonga/lib/CMakeFiles/libgroonga.dir/ts/ts_util.c.o /home/wmt/Downloads/mariadb-10.4.6/storage/mroonga/vendor/groonga/lib/expr.c: In function 'grn_expr_exec': /home/wmt/Downloads/mariadb-10.4.6/storage/mroonga/vendor/groonga/lib/expr.c:2620:1: note: variable tracking size limit exceeded with -fvar-tracking-assignments, retrying without /home/wmt/Downloads/mariadb-10.4.6/storage/mroonga/vendor/groonga/lib/expr.c:2620:1: note: variable tracking size limit exceeded Linking CXX static library libgroonga.a [ 38%] Built target libgroonga make: *** [all] Error 2 Does anyone have any idea why? Can I disable building this storage engine or something? Hamish

[Maria-discuss] Rolling upgrade to Galera 10.4 not working
by Tiemen Ruiten 01 Jul '19

01 Jul '19

Hello, I'm trying to do a rolling upgrade of a MariaDB 10.3 Galera cluster to to 10.4, following the instructions here <https://mariadb.com/kb/en/library/upgrading-from-mariadb-103-to-mariadb-104…>. (I had to adjust the wsrep_provider variable for Galera 4 to /usr/lib64/galera-4/libgalera_smm.so, not mentioned in the instructions). After I start the mariadb service, one mysqld thread uses 100% of one core for about 45 minutes, then I see the following in the log and mariadb restarts, repeating the same process: Jun 20 16:24:44 rubidium mysqld: 2019-06-20 16:24:44 0 [Note] WSREP: Trying to continue unpaused monitor Jun 20 16:24:47 rubidium mysqld: 2019-06-20 16:24:47 3 [Note] WSREP: REPL Protocols: 9 (4, 2) Jun 20 16:24:47 rubidium mysqld: 2019-06-20 16:24:47 3 [Note] WSREP: ####### My UUID: ddb4f4da-935f-11e9-bcff-8209857266f0 Jun 20 16:24:47 rubidium mysqld: 2019-06-20 16:24:47 3 [Note] WSREP: Server mariadb4 connected to cluster at position 6a1fd0aa-4739-11e5-af88-42756e861245:7403466644 with ID ddb4f4da-935f-11e9-bcff-8209857266f0 Jun 20 16:24:47 rubidium mysqld: 2019-06-20 16:24:47 3 [Note] WSREP: Server status change disconnected -> connected Jun 20 16:24:47 rubidium mysqld: 2019-06-20 16:24:47 3 [Note] WSREP: wsrep_notify_cmd is not defined, skipping notification.
