Ocfs announce - Aug 2004 - 1.0.13-1 released

All,

We are pleased to announce the release of OCFS 1.0.13-1. The list
of changes are listed below.

For the UnitedLinux/SuSe release, the i686 and IA64 rpms have been
built with the latest kernel, SP3-241.

For the Redhat AS2.1 IA64 release, the rpms have been built with
the e.43 kernel. The module will not load on AS2.1 IA64 kernels
< e.43.

For Redhat i686 kernels, Redhat's kernel ABI compatibility will
ensure that the module loads against all kernels, AS2.1 and EL3.

==================================================================RELEASE 1.0.13

There are two changes in this release, both concerning the
size of memory chunks allocated.
 
First concerns the memory block allocated to r/w directories.
Whereas the older release allocated 128K block of memory, the
newer release allocs PAGE_SIZE blocks. Whereas the overall size
of memory allocated has not changed, the number of contiguous pages
required for each allocation has. In the newer scheme, the 128K is
made up of 32 4K pages (on the ia32 systems). This has been done
to take care of the numerous ENOMEMs experienced due to lowmem
fragmentation on heavily loaded systems.
 
The second change concerns the amount of memory allocated to hold
the lockres hashtable. Now, instead of 32 4K pages, it requires
8 4K pages. Once again, this has been done to take care of the
ENOMEM error one encounters when mounting ocfs volumes on heavily
loaded systems.
===================================================================

Is there anyplace that mentions how to properly upgrade from 1.0.12 to this
new release?
