System Background: I am running CentOS 7 in a VM (in VirtualBox) on a host computer running Windows 10. My /dev/sda is on an SSD and then I have three 1TB HDDs /dev/sdb, /dev/sdc, and /dev/sdd configured into a RAID 5 drive called /dev/md5. The /dev/md5 is formatted as ext4 and is mounted to /raid5.



I wanted to bind mount both /home and /var to sub-directories in my RAID 5, /dev/md5.



The following steps worked just fine for /home:



mkdir /raid5/home
rsync -av /home/*/raid5 /home
mount --bind /raid5/home /home

nano /etc/fstab


/raid5/home /home none bind 0 0



I then restart CentOS and it boots no problem. I check df -aTh and both /raid5/home and /home show mounted to /dev/md5.



I follow the exact same process to bind mount /var and /raid5/var and upon reboot I can't even get to the login screen. Same exact commands were used, just substitute /var everywhere you see /home.

          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
