MxFS-Linux 3.5.0

This release included the following:

• Support for MxFS-Linux on RHEL4 Update 3.

• The timeout value for Export Group monitors now applies only to

how long the RPC probe will wait for a response before causing a

Virtual NFS Service failover. Previously, the timeout period also

included the filesystem availability probe.

•The mx vnfs command now includes an

--activitytype option to specify

the activity type. Previously, this option was available only on the

Management Console.

PolyServe Kernel Patches

Matrix Server 3.5.1 provides PolyServe kernel patches that correct

problems found in the RHEL4 and SLES9 kernels.

Patches for RHEL4

The PolyServe binary and source 2.6.9-34.EL and 2.6.9.42.EL kernels

contain the following PolyServe patches:

• 00_lock_rename.patch. This patch corrects a locking problem in the code

that implements the rename(2) system call in the Linux kernel.

Without this patch, the system may hang during rename operations.

• 01_imapping_race.patch. This patch adds a reference to a filesystem

inode when it is acquired to prevent a race condition that can occur

when the i_mapping pointer is performing sync operations. Without

this patch, the kernel will panic if the race occurs.

• 02_missing_page_release.patch. This patch fixes a direct I/O memory

leak when the page for the I/O is not currently mapped. Without this

patch, the system may eventually run out of memory and panic.

MxFS-Linux requires that this patch be in place.
