Root Partition Mounted Read-Only after Cloning

I have made a clone of a webserver system disk (Debian 8) using Clonezilla. On booting I got this error:



No OS Found


All the files seemed fine and the problem turned out to be the MBR. The disk originally had a different distro on it. Although Clonezilla reported that it had copied the MBR over, the old MBR remained. I replaced the MBR using Debian Rescue and the system booted but the root partition mounts readonly. The fstab mount option is errors=remount-ro, fsck reports the partition as Clean.



This then causes randon-seed and UTMP failures.



Where should I be looking for the error?




debian mount

  • No fsck errors, all mountpoints there? Can you add more technical details?

  • Have you tried mount -o remount,rw /dev/sda / (assuming root is on /dev/sda...)

  • Already done that but it doesn't fix anything in the boot process, still mounts ro

Check your /etc/fstab, it often contains UUID's. There's a program called blkid which allows you to retrieve those of partitions of the clone.

  • Clonezilla made a dogs dinner of the UUID translation, it translated the root uuid ok but left the swap uuid from the source drive, I corrected it manually after a 'remount-ro
    – Sabreur

  • I've never managed to get the UUID's working, perhaps because I always compile my own kernel. I always replace them in my /etc/fstab by the old "/dev/sdx". And I lived happily ever after.

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
