Pinned topic An issue with SLES 11 SP2 (linux 3.0 kernel) requires a fix

‏2012-09-01T14:37:40Z |
When GPFS is used on SLES 11 SP2 (Linux 3.0 kernel), under certain workloads (in particular when NFS export of GPFS file systems is involved) a deadlock in kernel code may occur. The problem is currently under investigation. Customers are advised NOT to upgrade to SLES 11 SP2 until a fix is available. This announce forum and the GPFS FAQ (http://publib.boulder.ibm.com/infocenter/clresctr/vxrx/index.jsp?topic=/com.ibm.cluster.gpfs.doc/gpfs_faqs/gpfs_faqs.html) will be updated when the fix is available.

    This problem has been addressed. Fixes in both GPFS and Linux kernel code are needed.

    GPFS fixes:
    3.3: APAR IV25465 (3.3.0.25)
    3.4: APAR IV25764 (3.4.0.16)
    3.5: APAR IV25763 (3.5.0.6)

    In Linux kernel, the fix was merged in the 3.0.45 kernel.org tree. In SLES11 SP2, the fix is available in 3.0.42-0.7.3. See https://www.suse.com/support/kb/doc.php?id=7011397 for details.
