[Linux-cluster] GFS2 crashes - sys_rename



Hey guys,

 

We run a 40 node webcluster (only apache, php processes) and the nodes keep on crashing with a kernel panic. For me it looks like the rename of a file/directory aint working. I found someone posting the same a few days ago and it should be fixed in kernel 2.6.32-358.2.1.el6, but that’s the kernel we’re running. And we just used fsck yesterday night to check for problems with the file system. So something doesn’t seem right.

 

Here are 3 crashlogs from 3 different nodes:

The call trace looks for me kinda the same on all nodes and after we rebooted ALL 40 nodes, the “bug” seems to be gone and the system is running fine right now. (it’s running 20 minutes now without rebooting, before that we had a reboot every half minute)

 

Do you know anything about that – how can we fix it?

It’s a webcluster and such crashes aren’t good. It should be online 24/7 but right now it doesn’t look that good.

 

Thanks in advance, Jürgen
