[Ocfs2-users] OCFS2 and berkeley database files

[Alexei_Roudnev]

Novell claim that they joined heartbeat2, evms manager and ocfs2
succesfully; if it work, then it provides the whole (and consistant, which
is very important) stack and eliminate some ocfsv2 problems (low o2cb
reliability, because they use heartbeat2 instead and heartbeat2 have not
o2cb problems by design).

They show it on SLES10 on last LinuxWorld, but I never tested such
combination.

Hello

In that case (failover of LDAP Server), you can use any local file system on
a failover device (mounted only on the active node) with heartbeat or other
cluster managers.

I was looking into OCFSv2 for failover clusters also. I expected to get rid
of the cluster manager controling the volumes. However the OCFS' own cluster
manager is less mature, so better go with Hearteat, Lifekeeper Redhat
Cluster or any other established failover product. That also solves the mmap
problem.

Of course, but if you want to setup a failover cluster with an
active-passive configuration, it is a possibility to use a setup with a
shared volume without sync.
