Re: [Linux-cluster] Issue with KDE with kernel later than 2.6.18-53.1.21



I'm having trouble getting the file system to mount after adding the rsize parameter. Here is my fstab entry:

/dev/vgdevl/shared /fs/shared                    gfs     defaults        0 0

I changed it to:

/dev/vgdevl/shared /fs/shared gfs defaults,rsize=8192 0 0

and when I try to mount the file system I get:

[root nfs2-cluster etc]# mount /fs/shared
/sbin/mount.gfs: error mounting /dev/mapper/vgdevl-shared on /fs/shared: Invalid argument

Looking though the man pages, it appears that the rsize switch should work. Any thoughts?

Thanks,

Randy

Great. Thanks. I'll give that a shot. I just need to find umount and mount that file system to see if it worked.

I had a similar problem. Reducing my rsize back to 8k from 32k fixed it. Problem root was the lock files in the .qt directory.

We are seeing a very strange issue with KDE with all kernels later than 2.6.18-53.1.21 on our cluster nodes. When users attempt to log into the machine using KDE, it never makes it to the KDE splash screen. The machine just hangs on a solid blue screen. I can then restart the Xserver and login using Gnome, and it logs in without any issues. Unfortunately, for us, KDE is the standard desktop environment used by our development group. I can reboot the the cluster to the 2.6.18-53.1.21 kernel and both KDE and Gnome work as expected. Obviously, I'd prefer to be running the latest kernel. I will gladly provide more info if needed. Any help or suggestions would be greatly appreciated.

Info about our cluster:
It is a 2 node cluster running Centos 5 with up to date patches. I am using the cluster as a NAS head to serve NFS mounts out to our network from an iscsi SAN.

Current running kernel:
2.6.18-53.1.21.el5  (Running this kernel so KDE logins work)

Most current installed kernel:
2.6.18-92.1.22.el5

Cluster packages:
lvm2-cluster-2.02.32-4.el5
cman-2.0.84-2.el5_2.3
