yum update (first in a long time) has broken clamd.exim

I have just run a 'yum update' on a Centos 7.2 server which updated several 
hundred RPMs.

The update worked fine with no errors or warnings

I then rebooted the server and now my EXIM is rejecting emails because the 
clamd service isn't running.

So I tried:

[root <at> ollie2 ~]# systemctl restart clamd.exim
Failed to restart clamd.exim.service: Unit clamd.exim.service failed to load:

openocd

Does anybody have openocd-0.9.0 RPM for CentOS6 x86_64? I was able to
compile F23's SRPM (along with two libraries - hidapi-0.7.0 from F19 and
libusbx-1.0.14 from F19) but it gives me only "Segmentation fault".
Unfortunately i'm too inexperienced to debug it by my own (gdb and
strace didn't help me).

Copying CentOS to new drive

I recently asked about copying a running system to a new drive.

As a postscript, I'm wondering if it would have been preferable 
to run the machine under a Live OS, and simply copy the root partition
to the new drive?
Eg while running under the LiveOS,
  # mkdir /mnt/old /mnt/new
  # mount /dev/sda7 /mnt/old
  # mount /dev/sdb6 /mnt/new
  # cp -avx /mnt/old /mnt/new
or
  # rsync -ax --progress /mnt/old /mnt/new

c6, drbd and file systems

I have a pair of centos 6 systems, with a rather large raid thats DRBD 
replicated from box 1 to box 2... box 1 mounts this as /data

when box 1 reboots, /data doesn't get mounted, but the drbd replication 
starts up just fine.   the entry in fstab is...

/dev/drbd0              /data           xfs     inode64         1 0

once the system is booted up, if I `mount /data`, it mounts just fine.

I'm not using any sort of heartbeat or other HA management software, if 
box 1 fails, I'll manually configure box2 to take over after physically 
disabling box1 so it can't wake up a zombie.

ImageMagick security alert

https://imagetragick.com/

As CentOS is often used for web servers, I thought this should be posted 
here.

Bug in ImageMagick allows remote exploit.

AFAIK no patch exists yet but defense against the exploit is detailed at 
the link.

CVE-2016–3714

Inconsistancy in RAID documentation

On the wiki page for creating a mirrored root drive, at
<https://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1>, it first
tells you, in the install, to chose manual partitioning, and to leave at
least 1M at the end of the drive.... and then it tells you to create the
RAID 1 using /dev/sda and /dev/sdb - the *whole* raw drives.

         mark, currently creating a RAID 1 using just the raw drives, no
partitions

Does journalctl --verify no longer complain of corruption? Or is it
possible there's corruption but journalctl and rsyslogd now tolerate
it somehow?

Copying a live system

I want to backup my current CentOS-7.2 system to another drive.
Is it safe to copy the system while it is running?
Eg by
mount /dev/sdb5 /mnt
rsync -HPaxvz /. /mnt/
I've found contradictory advice on the web.
