Installing TSM Tivoli Client 6.4 or 7.1 on RHEL7 / CentOS 7 with Failed dependencies: libc.so.6 is needed

Today I got a problems installing TSM Tivoli Client 6.4 and also 7.1 on CentOS 7.
Commands I run

rpm -Uhv gskcrypt64-8.0.14.14.linux.x86_64.rpm
rpm -Uhv gskssl64-8.0.14.14.linux.x86_64.rpm
rpm -Uhv TIVsm-API64.x86_64.rpm

doing than

rpm -Uhv TIVsm-APIcit.x86_64.rpm

gives error message

and after resolving first error I got

libgcc_s.so.1 is needed
...

and than I got

libstdc++.so.5 is needed
...

this also is true for trying tsm tivoli 7.1 client version
Solution was to install missing Linux 32-bit libraries [1] as tsm relies on them

yum install libgcc.i686
yum install libstdc++.i686
yum install compat-libstdc++-33-3.2.3-72.el7.i686

Fixing installation errors for installing CentOS 7 on Mac Mini 2011 with USB media

This morning I tried to install CentOS7 on an Apple MacMini from 2011 with a USB stick. After grub and the initram fs has been loading there was the following error

dracut-initqueue[639]: Warning: Could not boot. dracut-initqueue[639]: Warning: /dev/root does not exist. Starting Dracut Emergency shell.

This error often occurs by a mismatched usb media label and can easily be resolved by using UUID instead of label in grub2 initram fs kernel arguments [1].

The following steps have been taken form unix stackexchange on how to fix this:

1. starting from the Dracut Emergency shell, find out which device name is your installation usb stick.
2. get the uuid for this device name, write it down.
3. reboot and replace grub2 initram fs kernel arguments from using LABEL to UUID.
The exact procedure can be found here

4. start the installation with the changed kernel arguments, this is a bit tricky because running a changed grub2 command line needs the keyboard combination ctrl-x which does not work on a mac computer [2].
This also does not work when using a PC keyboard on this mac.
Solution was to use a PC keyboard and type F10 instead of CTRL-X work the same on mac to run a changed command line. I tried pressing F10 on a mac keyboard (fn+F10 key) but did not work.
But using a PC keyboard on the mac and hitting F10 worked and booted up the graphical installer.

Resolving DRBD error lk_bdev_save (/var/lib/drbd/drbd-minor-0.lkbd) failed: No such file or directory on centos 7 system

Hi everyone! Just a small post here because I have not found anything about this error on the web (at least not on a english-speaking website ;) ) I recently installed and configured drbd on a centos 7 machine. drbdadm came in version 8.9.2 (api:1) GIT-hash: de9236084d57a09160b366e5fdf5b481c5cc163d build by mockbuild@, 2015-04-10 06:40:59 when I tried to create my resource I got the following error

$drbdadm create-md drbd01

error msg:

initializing activity log

NOT initializing bitmap

Writing meta data...

lk_bdev_save(/var/lib/drbd/drbd-minor-0.lkbd) failed: No such file or directory

New drbd meta data block successfully created.

lk_bdev_save(/var/lib/drbd/drbd-minor-0.lkbd) failed: No such file or directory

searching the internet I found nothing about it so I just looked at the error and resolved it using

mkdir /var/lib/drbd/

I think the rpm package from ELRepo I installed just missed that command. Hope this helps anyone
