Ceph mon and radosgw upgrade - storage

Are there any worries about upgrading ceph-mon and ceph-radosgw to affect OSDs data?
The problem is our versions are like this :
ceph-mon 13.2.6
ceph-osd 15.2.1
ceph-radosgw 13.2.6
As you can see OSD is version 15.2.1 and two others are 13.2.6

Azul Systems JRE 11.0.6

Most of our systems are on Azul Systems JRE 11.0.6, which is causing a tremendous amount of vulnerabilities.
The recommended solution on fixing these issues is to upgrade to version 18 (latest version).
Is there any particular reason why a legacy version is still being used and not being upgraded? (ie dependancies)
Any follow up would be greatly appreciated.
Thank you!

What's the current Vaadin LTS version?

My project has a bug. It currently uses v18.0.3. When I asked a question in another thread someone mentioned that I should better upgrade to v21, since that's an LTS version. I also recall having received news letters stating that v21 is supposed to be an LTS version.
If I looked at the Vaadin Roadmap (https://vaadin.com/roadmap) today there is no word that v21 is an LTS-version.
Rather v14 is mentioned as last LTS and v23 is apparently to become the next LTS version.
Have plans changed?
The most recent versions can be found here https://vaadin.com/releases
you'll see that 14 is the current LTS
You should definitely update from 18 to 21 even if 21 isn't an LTS version, because 18 is no longer supported. It'll also potentially make your update easier when the next LTS, 23, is released. With non-LTS versions, you should always update to the latest major to stay on a maintained version.

EMC Solution Enabler

I would like to install EMC Solution Enabler on RHEL 7.1 and 86_64.
Please advice which version is supported with this configuration.
Note: I want to have this software because I would like to use 'syminq' command to get storage information in the host.
Thanks
Doesn't look like its supported on RHEL 7.1 . The latest seems to be RedHat Enterprise Linux 6.0/6.2 , as per the below latest release document :
http://uk.emc.com/collateral/TechnicalDocument/docu61129.pdf
It mentions that Solutions Enabler V8.1 installation requires i686 version of
glibc (GNU C Library) and libgcc (Library of GCC support routines) packages pre-installed. If your RHEL 7.1 host doesn't have the those , it also mentions of a work around. Hopefully it should work for RHEL 7.1 too.

Can't insert spaces in code editors

Since i recently installed CodeBlocks, I can't insert spaces in codeblocks, codelite or mysql-workbench editors.
When i press space the editor interprets it as a completion key unless there is no word to complete.
The only way to insert a blank space is to press "Supper+Space".
I tried to remove CodeBlocks and CodeLite but the problem persists in Mysql Workbench.
Configuration :
uname -a :
Linux slxpc 3.2.0-57-generic #87-Ubuntu SMP Tue Nov 12 21:35:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
cat /proc/version
Linux version 3.2.0-57-generic (buildd#toyol) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #87-Ubuntu SMP Tue Nov 12 21:35:10 UTC 2013
mysql-workbench --version
MySQL Workbench CE (GPL) 6.0.8 11354 build 833
CodeBlocks version : 10.05
FYI : I don't have this problem in geany and leafpad.
The common base for these 2 editors (codelite / codeblocks) is that both are using wxWidgets as their underlying GUI toolkit.
So its probably related to this fact.
You failed to mention 2 important details:
Your keyboard layout ( I assume that you don't use standard keyboard )
Your codelite version
I can advise you for codelite
Upgrade to the latest version of codelite (which uses a much more recent of wxWidgets). You won't find the latest version of codelite in Ubuntu's repositories since its using an up-to-date version of wxWidgets which is not included by Ubuntu's packagers, you can however, find it in codelite's repository: codelite download page
Once installed, it should fix your problem. If the problem persists, change the code completion keyboard shortcut to something else (e.g. Ctrl-ENTER) from Settings -> Keyboard Shortcut
If both methods fails, you can always switch to work with standard keyboard

Snow Leopard install Ruby on Rails (with MySQL)

I've done a clean re-install of OS X Snow Leopard, so there's nothing on my system at all.
I've installed Xcode and I'm ready to install Rails.
However, my system is a MacBook (MacBook2,1) and apparently it doesn't support 64-bit by default. Apple is going to add this at a later date.
How would I go about installing Rails? Do I go about it the normal way?
How about MySQL, do I need the 64-bit binary?
Most of the time (maybe always, I'm not really sure) you can run binaries compiled for 32 bit even if your system is 64 bit. They just won't have any benefits of 64 bit (either storing bigger things or processing stuff faster).
If your macbook is a recent one it has 64 bit support (Core 2 Duo processor), if it is an older version (Core Duo) it is 32 bit. You can determine the processor type by checking 'About this Mac' in the Apple menu.
You can certainly install the 64-bit packages. They will be able to access the memory space and every advantage of running with 64bits. The only thing that won't boot in 64bit is the Kernel, but it's not something to be worrying about for the moment.
Check out the Hivelogic's guide for installing MySQL, Rails and Ruby on Snow Leopard:
MySQL
Git
Ruby, Rails
Your MacBook does support 64bit, but it cannot boot in 64bit mode. You should be able to install 64bit binary packages just fine.
You should definitely install the 64-bit binory packages such as mysql.
