problem with disappearing db
I just had a strange problem with an installation of couchdb.
After restarting the couchdb service, it seems it can't access anymore to
some of the dbs that were there before.
The files of those dbs seems to be still present in the shards folder, but
after the restart, it seems the system can't access them.
Just before the restart, the dbs were there and working regularly, there
was no delete operation.
The couchdb configuration, at least to my knowledge, did not change since
installation, and by my check seems to be the standard one.
Couchdb is version 2.3.1.
I've also tried on a different machine copying one of our previous
timed-backups (we do a daily snapshot of the whole couch db folders), but
once restored seems to have the exact same problem: the couchdb service
comes up, but the "documents" and "main" dbs are missing.
I've no idea were to start debugging this, and if there is a way of
recovering those dbs from the backup I've right now.
Anyway, the logs during the restart are the following:
