SQLite Recovery

gromox-dbop and gromox-http may refuse a database schema upgrade when a consistency check is negative:

http[2557]: Upgrade of /var/lib/gromox/domain/1/exmdb/exchange.sqlite3 not started because of 6 integrity problems
http[2557]: dbop_sqlite upgrade /var/lib/gromox/domain/1/exmdb/exchange.sqlite3: Input/output error

A few details may be obtained by rerunning the same integrity check in a sqlite3 command line:

# sqlite3 /var/lib/gromox/domain/1/exmdb/exchange.sqlite3
sqlite> pragma integrity_check;
integrity_check
--------------------------------------------------
row 202171 missing from index state_username_index
row 208269 missing from index state_username_index
row 208282 missing from index state_username_index
row 208284 missing from index state_username_index
row 225182 missing from index state_username_index
row 226595 missing from index state_username_index

When (just) indices are broken, the file may be recreated:

cd /var/lib/gromox/domain/1/exmdb/
sqlite3 exchange.sqlite3 .recover >recover.sql
mv exchange.sqlite3 exchange.sqlite3.old
sqlite3 exchange.sqlite3 <recover.sql
chmod u=rw,g=rw exchange.sqlite3
chown grommunio:gromox exchange.sqlite3
systemctl restart gromox-http
