I have a mdadm software RAID6 that comes up inactive upon each reboot. All its disk are present but shown as spares. How do I make it start operational (active)?



This is it's state after reboot:



cat /proc/mdstat 
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] 
md0 : inactive sdg[2](S) sdf[1](S) sde[3](S) sdc[5](S) sdb[0](S) sda[4](S)
 xxxxxx blocks
unused devices: <none>


again here



sudo mdadm --detail --scan 
INACTIVE-ARRAY /dev/md0 metadata=0.90 UUID=xxx


It can be manually assembled after I stop it:



sudo mdadm --manage --stop /dev/md0
mdadm: stopped /dev/md0
sudo mdadm --assemble --scan
mdadm: /dev/md0 has been started with 6 drives.
sudo mdadm --detail --scan
ARRAY /dev/md0 metadata=0.90 bitmap=/media/intent.bin UUID=xxx


I'm on Ubuntu 18.04.1 LTS

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
