Thank you Trevor/Digimer. I cannot goahead and use the latest CentOS. Am running one application in CentOS 6.3 (My Appln will support only 6.3). But my requirement is to upgrade the kernal (2.6.32-279.9.1.el6.x86_64) . Whether existing drbd version(drbd-kmdl-2.6.32-279.el6-8.3.11-31.el6.x86_64) will support for this Upgraded kernal or i need to upgrade my drbd version seperately? Thanks, Madhan. ________________________________ From: Digimer <lists at alteeve.ca> Sent: Thursday, January 19, 2017 11:08 PM To: Trevor Hemsley; pillai bs; drbd-user at lists.linbit.com Subject: Re: [DRBD-user] DRBD for the upgraded kernal On 19/01/17 08:27 AM, Trevor Hemsley wrote: > On 19/01/17 12:55, pillai bs wrote: >> >> Hello Experts! >> >> >> Am having cluster in below setup >> >> CentOS: 6.3 >> >> Kernal : 2.6.32-279.el6.x86_64 >> >> Installed drbd rpms: >> >> 1. drbd-kmdl-2.6.32-279.el6-8.3.11-31.el6.x86_64 >> 2. drbd-8.3.11-31.el6.x86_64 >> >> The setup was in good shape.

If you must stay on 8.3, upgrade to the latest 8.3.16 (or 8.3.17, if it was released). In any case, you should always have a test cluster. If you don't, please create one (even in VMs is better than nothing) to match the current version of your cluster and test the upgrade there first. We will never know your environment well enough to say "this is safe". If you want commercial support, LINBIT (the company behind DRBD) offers commercial support and official releases. -- Digimer Papers and Projects: https://alteeve.com/w/ "I am, somehow, less interested in the weight and convolutions of Einstein's brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops." - Stephen Jay Gould -------------- next part -------------- An HTML attachment was scrubbed...
