Description dijuremo 2010-03-05 12:44:31 UTC

Description of problem:
drbd (a distributed replicated block device) has been included in the linux kernel as of 2.6.33

http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.33

commit 456eac94789e1b512515e6974e091ef655f343de
Merge: dedd0c2 f06f135
Author: Linus Torvalds <torvalds>
Date:   Thu Jan 21 07:32:11 2010 -0800

    Merge branch 'for-linus' of git://git.kernel.dk/linux-2.6-block
    
    * 'for-linus' of git://git.kernel.dk/linux-2.6-block:
      fs/bio.c: fix shadows sparse warning
      drbd: The kernel code is now equivalent to out of tree release 8.3.7
      drbd: Allow online resizing of DRBD devices while peer not reachable (needs to be explicitly forced)
      drbd: Don't go into StandAlone mode when authentification failes because of network error

It would be very useful if it is added to RHEL 5.X and RHEL 6 as well as the userland tools, such already seems to exist for Fedora Core 12, see

Comment 4 Ray Van Dolson 2010-04-28 18:55:16 UTC

You'll definitely want to file an RFE SR for this as well.

Do we need a separate bz for RHEL6?

Comment 5 dijuremo 2010-04-29 17:11:24 UTC

Our people with support contracts have opened SR #2017020

Comment 6 Alexander Lindqvist 2010-07-22 13:51:57 UTC

+1. Please add DRBD support to RHEL5. We use it in production on several servers.

Comment 7 Tom Coughlan 2011-02-09 18:42:22 UTC

Linbit/DRBD hs been added to the Red Hat Partner Center:

https://www.redhat.com/wapps/partnerlocator/web/home.html#productId=60400

Red Hat will partner with Linbit to provide DRBD support, rather than include it directly in RHEL 5 (or RHEL 6).
