[Ocfs2-users] RAC OS Migration

[Karim Alkhayer]

>> Hello All,

>> We've been finally given the green light to consider the upgrade to the
latest available OCFS2 version
>> Currently, we're running RAC 10.1.0.5 on a two-nodes cluster, and there
are no plans at the moment to upgrade Oracle software version

>> My concerns are the following:

>> 1) The OS upgrade vs. OS fresh install
>> We're running SLES9 SP3 Kernel 2.6.5-7.257. SLES10 SP2 is the target that
ships ocfs2 1.4.1.

>> 2) OCFS2 upgrade via tune.ocfs2 vs. mkfs after OS upgrade. 
>> Obviously, if we did the fresh OS install, we will have to rebuild the
RAC cluster/software again. 
>> However, using tune.ocfs2 to enable the new features might cause
stability issues with respect to operating the 
>> cluster file system.

>> I'd like to place a safe/simple migration plan so that we can place the
RAC back to business ASAP 

Appreciate your input
