[SOLVED] /var/spool/postfix missing each reboot

Everytime i reboot my NAS it wont send email and after checking the mail.log i see the following error

Aug  3 20:57:41 openmediavault postfix/postdrop[4788]: warning: mail_queue_enter: create file maildrop/644233.4788: No such file or directory
Aug  3 20:59:46 openmediavault postfix[2784]: fatal: chdir(/var/spool/postfix): No such file or directory

i look in /var/spool and the folder is gone, This causes OMV to stop sending mail

if i recreate the folder it sends emails fine, The cron folder stays put inthe spool folder across reboots

root@openmediavault:/var/spool# ll
total 0
drwxr-xr-x 3 root root 60 Aug  3 21:05 cron

i recreate the folder and its OK until i reboot

root@openmediavault:/var/spool# ll
total 0
drwxr-xr-x 3 root root 60 Aug  3 21:05 cron
drwxr-xr-x 2 root root 40 Aug  3 21:10 postfix

its driving me crazy

there are a few strange things going on i think i will reinstall, follow your backup how to once its complete and keep it safe

i reinstalled omv, and installed all my programs that i had before, and its doing it again.
upon reboot, the /var/spool folder does not contain postfix.
if i turn disable email in the omv guy and then re-enabe it, it recreates all the folders under postfix and and all is well.
I do not think this is my SSD

i put mkdir /var/spool/postfix in rc.local and this creates the folder but it does not allow postfix to populate the folder with all the other folders that are supposed to be there.

iso, but I have a ssd drive in my machine and I followed advice that said to put /var/log /var/spool & /var/cache on a tmpfs so that the constant read/writes wouldn't lessen the life of my ssd, i have found a page that points to this as maybe causing the problems.

it IS that!!
i reversed the entries in fstab and now its working!!!!
sorry for the panic :oops:

i found the following script i will try tomorrow, re-enable fstab entries and try again

#!/bin/bash


# Script to create required directories in tempfs /var (that are not otherwise created)

for dir in apparmor apt ConsoleKit cups dist-upgrade fsck gdm installer news ntpstats samba speech-dispatcher unattended-upgrades; do
  if [ ! -d /var/log/$dir ] ; then
    mkdir /var/log/$dir
  fi
done


for dir in cups-pdf anacron postfix; do
  if [ ! -d /var/spool/$dir ] ; then
    mkdir /var/spool/$dir
  fi




done

the above is NOT the fix
i followed a post about moving the tmp folders off of the SSD into ram, and it was this, i reversed it and put everything back and its now OK
