[Ocfs2-users] Latest OCFS V2 causes OCFS V1 to crash and hang?
Some history on the cluster first. The 16 node IA32 cluster is running Redhat 2.1 2.4.9-e.35smp kernel. It originally had OCFS V1 V1.0.9-12 with few issues. We installed OCFS V2 BETA1 and tools and support V1.9.9-1. We didn't have any problems with OCFS V1 and since we only created an empty mount point with OCFS V2, we didn't have any issues there either. We very recently upgraded from OCFS support tools 1.1.0-1 to 1.1.1-1. This was done as a prerequisite for OCFS V2 BETA2. We also upgraded OCFS V2 to 1.9.91-1. We recreated the empty mount point and actually untarred an Oracle Home to it. We haven't really used it yet because the cluster has been unstable ever since even without the OCFSV2 device mounted. Two of the nodes crashed. Here is the stack trace. I had to enter this manually as HP sent me a JPG file which made the post too large.;-( Call Trace: [<f8e7ab48>] OcfsGlobalCtxt [ocfs] 0x8 ocfs_dismount_volume [ocfs] 0x386 .LC2 [ocfs] 0x600 ocfs_dismount_volume [ocfs] 0x3b7 ocfs_read_super [ocfs] 0x2f1 .LC99 [ocfs] 0x131d get_sb_bdev [kernel] 0x210 do_kern_mount [kernel] 0xe4 ocfs_fs_type [ocfs] 0x0 ocfs_fs_type [ocfs] 0x0 do_add_mount [kernel] 0x23 do_mount [kernel] 0x13b __alloc_pages [kernel] 0xf copy_mount_options [kernel] 0x4c sys_mount [kernel] 0xa4 system_call [kernel] 0x33 Also, the node hangs during startup if the OCFS V1 mount script is executed even with the mount of the OCFS V2 device commented out.

Any assistance is appreciated as we want to test OCFS V2 and also have a shared Oracle Home. -- Regards, Walter -------------- next part -------------- A non-text attachment was scrubbed...
