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.

The version is indeed stored in database to compare with sources.

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 On 2021-12-30 7:03 pm, Fridolin SOMERS wrote:

Hi,

Looks like your database "library" has some issues. The version is indeed stored in database to compare with sources. Looks like "library" version is 21.06.00.006, so previous database upgrade failed also ?

This problem may be described in : https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=29728

Best regards,

Hi all

Just upgraded tonight koha-common 21.11.01-1 to 21.11.00-1 This is on a Debian 10.11 (deb http://debian.koha-community.org/koha stable main). I got this error:

ERROR - {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Row size too large. The maximum row size for the used table type, not counting BLOBs, is 8126. You have to change some columns to TEXT or BLOBs at /usr/share/koha/lib/C4/Installer.pm line 738

That's a bit worrying. Though our Koha instance seems to be OK.

Full transcript of the upgrade is below.

Also why does the upgrade at one stage say "Upgrade to 21.06.00.007" when its upgrading from 21.11.01-1 over 21.11.00-1 ? Has the database got its own version?
