Hi Alessio,

After days sorting the Heartbleed mess, I managed to set up Debian Squeeze amd64 for the test and I'm seeing the same error message:

Fatal: nfs flush requires mail_fsync=always

# doveconf -n | egrep 'fsync|nfs'
mail_fsync = always
mail_nfs_index = yes
mail_nfs_storage = yes

Cheers,

Wesley

Hi,

I'm using Maildir on Debian 6 64bit, try to "grep" for "fsync" on all configuration files.

Try also to install the same dovecot+configuration on Debian 6.

Let me know!
Ciao

Hi Alessio,

I have 2.2.12 installed in Debian Wheezy amd64 server. mail_fsync is
specified and detected.  Are you using mbox or maildir or dbox? We're
using mbox and seeing the error.

# dovecot --version
2.2.12

# dovecot -n | grep -E 'sync|nfs'
mail_fsync = always
mail_nfs_index = yes
mail_nfs_storage = yes


# egrep 'nfs|fsync' 10-mail.conf | egrep -v '#'
mail_fsync=always
mail_nfs_storage = yes
mail_nfs_index = yes

# uname -r
3.2.0-4-amd64

Cheers,

Wesley

Hi,

I need to place a maildir storage on a NFS filesystem, so I set up
the config like this:

mmap_disable = yes
mail_nfs_storage = yes
mail_nfs_index = yes
mail_fsync = always
lock_method = dotlock (also tried fcntl - local lockd is running, no
success, now using dotlock, to be sure while debugging)

The problem is that Dovecot (2.2.9/2.2.10 - the relevant code in
mail-index.c is the same) logs a fatal error and quits the session
(no daemon crash/coredump).

Hi,

I have a similar configuration but with dovecot 2.2.12 and NFS for me
works fine. Have you insert the "mail_fsync = always" in the right
place? Is there only one "mail_fsync" setting in your config? First
check this:

root@mx:/etc/dovecot# grep mail_fsync /etc/dovecot/ -R
conf.d/10-mail.conf:mail_fsync = always

root@mx:/etc/dovecot# dovecot -n | grep -E 'sync|nfs'
mail_fsync = always
mail_nfs_index = yes
mail_nfs_storage = yes
maildir_very_dirty_syncs = yes

# 2.2.12: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.9

Let me know.
Ciao
