[Koha] Error DBI Exception, maximum row size is 8126 during upgrade to Koha 21.11.01

[Mike Lake]

Hi

Thanks Fridolin for the link to bug 29728.
All of my tables in our Koha instances "opac" and "libtest2" are 
DYNAMIC.
# mysql -e "SELECT table_name,row_format FROM information_schema.tables 
WHERE table_schema='koha_opac' and row_format='Dynamic';" mysql

However you picked up that the error was for Koha instance "library". 
That was an old instance that had not been updated for some time. The 
instances opac and libtest2 upgraded OK. A few nights ago I purged 
"library" as it was not needed. (Unfortunately before I learn about 
row_format as I could have checked what it was.)

So I think all is OK with our production and test and now I have learnt 
a bit about the row_format and how to check that setting. It's default 
setting in MariaDB is DYNAMIC.

Excellent. Where is this stored? I had a quick glance through the schema 
dump but did not see it. In mine I should see 21.11.01.000 stored or 
something like that.


Thanks
Mike
