After upgrading to 5.7.23 the error changed to

Creating index 'FTS_DOC_ID_INDEX' required more than 'innodb_online_alter_log_max_size' bytes of modification log.

The database doesn't use any FULLTEXT indexes.

Hi,

I don't see how to reproduce this issue?

thanks

It fails repeatedly here but I don't know how to create an example you can reproduce.

Hi,

> It fails repeatedly here but I don't know how to create an example you can reproduce.

for start you can give me create table, you gave only show table status since that would be a start position, creating random table and modifying column obviously don't reproduce your issue.

Did you check that table? Have you tried copying that table into other database and altering it to see if it would crash again (create table x like y; insert into x select * from y; alter table x...) as it's possible there's a table issue.

with the data provided, there's really nothing I can do

all best

ERROR 1846 (0A000): LOCK=NONE is not supported. Reason: cannot silently convert NULL values, as required in this SQL_MODE. Try LOCK=SHARED.

What sql_mode are you using?

p.s. this might be duplicate of Bug #77097 but I'm not yet sure

I assume the ALTER will complete with a large enough value for innodb_online_alter_log_max_size.

I haven't tried that yet.
[25 Apr 2019 2:40] monty solomon
I can also try using pt-online-schema-change since it will create a new table.

of course, you have to have proper configured server for it to work properly but that's not a bug.
