MySQL multiple instance docu. Should not be a problem if each user only runs Akonadi on one of the machines sharing that volume at a time. Different users have different Akonadi databases. And if your NFS installation has working locking, you won't corrupt your data if you try, just fail to access it. (That said, NFS locking tends to be broken one way or the other, so I'd suggest being careful and not attempting to run Akonadi concurrently on multiple machines for any given user.) > InnoDB tables should not be used on NFS. This is pretty much the same as the above, only this time when the locking is working as designed. From the given link: > It is not a good idea to configure InnoDB to use datafiles or logfiles on > NFS volumes.

Again, that shouldn't happen if you only run Akonadi on one of the machines sharing that volume at a time, and you won't be affected by other users' locks because the database is per user. Pretty much the same kinds of corruption or lock contention would happen if Akonadi was using flat files. Having processes on 2 computers manage the same NFS-shared file is always a bad idea, with or without MySQL. > NFS speed: MySQL documentation recommends against locating its data files > on network shares. That's a valid concern, but I don't think it will be that big a problem.
