Re: Fatal: nfs flush requires mail_fsync=always

[Juan C. Blanco]

Hello, any news about the attached error?

I'm preparing the 2.2 to 2.3 upgrade and having the same error.

We have the mail stores in an NFS filer.

Regards

Hiya all,

I'm seeing this "Fatal: nfs flush requires mail_fsync=always" error on
my testbed. The issue is that from what I can see, mail_fsync is set
to always :

# doveconf -n | grep mail_fs
mail_fsync = always

The result is that the client does not connect at all, which is not
really what I wanted to happen :)

Any idea what is going wrong here?

Best regards
