Thank goodness they had tools to see which user placed locks, so all you had to do was find the user. |
I know
Been there, done that, used said tools...
I understand the reasons why using two instances of Calibre on the same library at the same time is asking for major trouble; exactly because the DB backend does not have said locking protocols. I also understand (or at least accept; my knowledge of file system semantics does not reach to really understanding it) that having your metadata.db on an SMB share isn't a good idea, even if it seems to work fine for months or even years.
But that doesn't make 'using a file' on said share 'risky'. Like I said, people have been doing it for years. Yes, it's not the same as local storage, but that's not local storage vs. network storage, that's single user vs. multi-user (or just multi-process). Having your stuff on a local disk isn't inherently safer than having it on a remote share of some sort.
