Hi Team,

Could you please help me with the below error msg. The same dump works well with NFS storage. But it is failing with CIFS.

pg_restore: error: could not execute query: PANIC:  could not fdatasync file "0000000100000001000000E9": Bad file descriptor
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
Command was: ALTER TABLE ONLY nsp_contact
    ADD CONSTRAINT nsp_contact_casnum_constraint PRIMARY KEY (casnum);

That is not a PostgreSQL problem, that is a kernel problem related to your cifs mount. You'll need to check that with the kernel people.

That said, I would strongly advise you *not* to run PostgreSQL on a cifs mounted partition in general. This type of filesystem errors being one of the reasons for that.
