An mdadm question

CentOS 7.

I have a server with four drives. 1 is /, and the other three are in
RAID5. I need to pull a drive, so I can test whether the server can read >
2TB drives. I've been googling, but don't want to screw the server up....

I think I'd like to
  1. stop the RAID
  2. pull a drive
  3. put in a large drive, and run parted, and mkfs
  4. pull the large drive
  5. replace the RAID drive
  6. fire up the RAID.

So, can I do it in that order? Do I need to fail something?

We have recently been asked to evaluate some computing machinery for
a new project. This particular end user has very limited experience
with the stated security requirements in a lights-out environment.
Their primary work (as well as mine) in the past has been with very
small, simple networks of desktop machines and a few servers with
extremely limited access.  For the most part, their admins haverefused to use any maintenance
connectivity to servers other thanthe primary serial ports.

There is a concern about system security primarily driven by recent
information searches performed by end user admins and included below.

IPMI/BMC Security Issues
------------------------   Search:  IPMI "Security Holes" -- Hits: 14,500   Search:  IPMI BMC "Security Holes" -- Hits: 4950

BIOS Security Issues
--------------------   Search:  BIOS "Security Holes" -- Hits: 342,000

My initial recommendation was to use a totally separate network for any
service processors within the servers that implement IPMI/BMC capabilities.
This has been standard practice in most systems I have worked on in the
past, and has allowed certification with essentially no problems. The BIOS
concern seems to be another issue to be addressed separately.

Any connectivity and access to a system brings security issues.  The list
from these searches is huge.  Are there specific things that must always be

Problems with Samba-based Home-Directory

Hi folks,

I'm running CentOS 6.6 on my workstation. There I have a user meikel, 
and its home directory /home/meikel ist stored on a samba share on a 
server which also runs CentOS 6.6.

In the very beginning I added the mount options for that home directory 
into the /etc/fstab file which led to some problems, so I set up autofs 
for mounting the home directory.

The autofs seems to work for /home/meikel, but sometimes when I login at 
the GUI, I get error messages which look a little as if the home dir 
isn't available, I then also don't get my desktop background image. The 
two error dialogs which I get in that situation show the following messages:

   "Could not update ICEauthority file /home/meikel/.ICEauthority"


   "Es gibt ein Problem mit dem Konfigurationsserver. 
(/usr/libexec/gconf-sanity-check-2 beendet mit Status 256)"

Sorry for the german, it's not clear to me how to get it in english. 
It's something like "There's a problem with configuration server. 
(/usr/libexec/gconf-sanity-check-2 terminated with exit-code 256)"

To do some analysis I did the following:

- Restart workstation, wait until login screen appears

What causes phantom update nags?

My Update Applet keeps giving me messages to install an update to a
package I do not have installed. To make matters more confusing, when I
actually try to install the package it wants to update, there is a
problem with the installation.

Any tips on how to resolve this?  Is this somehow caused by the
repositories I have enabled?

USB stick query

I have a working CentOS-7 machine.
I want to install grub2 on a USB stick
(without altering my present system in any way)
so that I can boot the present system from the USB stick.

Could some kind (and expert) soul explain precisely what to do.

If it were possible to boot other systems on the computer as well
that would be an added bonus.

I did google for this, but all the sites I saw
wanted to do more than I am asking.
I also tried "sudo grub2-install /dev/sdb"
but for some reason this did not do the trick.

gssproxy items...


I've been working on some systems trying to get kerberized nfsv4 and
kerberized web services going on 7.  Kerberized nfsv4 was working with
7.0, but with the 7.1 release it stopped working, the key difference
between the two setups is that gssproxy wasn't being used with 7.0, but
seems to be key with 7.1.

The problem I am encountering with Kerberized NFSv4 is that the
directory will mount okay, and I can see it's contents as root, but I
encounter "Permission denied" errors when trying to access it as a
regular user.  'klist -ce' returns valid results as the user (including
a a line for the server spn that I was trying to access), and I am able
to access Kerberized NFSv4 shares hosted on EL6 servers as the same user.

Kerberized web services have been a recent thing to try in order to see
if they would work with gssproxy - a colleague did get Kerberized web
services going on 7.1 without using gssproxy.  I followed the
instructions at, but
still didn't have any success until I added the cred_store line
mentioned in comment 6 of as we are running
with selinux enabled.  The success was short-lived for once I started
adding user/group checking it would succeed about 30% of the time as the
user principal was being returned as
elaxdal <at> REALMH\x86\xf7\x12\x01\x02\x02 instead of just elaxdal <at> REALM.

Today I tried recompiling the 0.4.1-1 source rpm from Fedora 21's
updates, installed it onto a 7.1 nfsv4/web server, at which point
everything started to consistently work - NFSv4 shares and web services
