Re: [Ocfs2-users] ocfs2 node reboot method
I believe 1.2.5-SLES-r2997 is the version of the fs and not the tools. Meaning, an upgrade is required to the latest kernel that is shipping 1.2.9. As far as failure to mount goes, one reason could be that the default timeout (10 secs) could be low. See if increasing to the new default of 30 secs helps.

[Ocfs2-users] Enable mlog() messages
Hello again, I looked into the source and found the error message "Transport endpoint is not connected" could be came from ENOTCONN in tcp.c. There are multiple ENOTCONN, so I would like to know which one produce my message. I want to enable mlog(). My understanding is, debug.ocfs2 enable the mlog(). http://oss.oracle.com/osswiki/OCFS2/Debugging I think my problem happen while the system boot up and mount the volume from /etc/fstab. In that case, how can I enable debugging? Regards, Masanari Iida ___ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com http://oss.oracle.com/mailman/listinfo/ocfs2-users

I would like to catch some useful information for troubleshooting. Do you think tcpdump may catch something? Or Do I need to use debug.ocfs2? If latter case, what is the right option?

Normally it happens when there are some protocol collision among nodes. Any helpful information in "dmesg"? also please provide the version info of ocfs2.

[Ocfs2-users] ocfs2 node reboot method
Hello list, There is a 14 node OCFS2 cluster. When I reboot all 14 nodes at once, some node failed to mount the ocfs2 filesystem while rebooting. The mount is supposed to be done by /etc/fstab. The symptom is happened on randam node. I would like to know if there is such a rule that OCFS2 nodes need to be reboot one-by-one, instead of all-at-once. An error message I saw was mount.ocfs2: Transport endpoint is not connected while mounting /dev/EXTDISK/OCFS2 iptables is not set on each nodes.
