having temp_tablespaces on less reliable storage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello list,

I have a database split across many tablespaces, with temp_tablespaces pointing to a separate, less reliable device (single local NVMe drive). How dangerous is it for the cluster to be unrecoverable after a crash?

If the drive goes down and the database can't read/write to temp_tablespaces, what will happen?

If I then configure temp_tablespaces to point to a working location, would that be enough to start the cluster? Or other bad things can happen?

Can't find any related documentation, but I expect loss of "temp" space is of minor importance.

Thanks in advance,
Dimitris
