[Linux-cluster] accessing GFS with fail of one cman

[Paul Morgan]

Do you have a /dev/sdf?
And if so does it have a gfs or gfs2 filesystem, or is the filesystem on /dev/sdf1 (a partition)?

If in doubt, use gfs_tool &/or gfs2_tool to examine the sb (superblock) of the device you're trying to mount.

Hth,

so although i managed to set run this cluster - i don't know why i
didn't try this earlier, i am still not able to mount the GFS, I am
still geting the same error message:
/sbin/mount.gfs: error mounting /dev/sdf on /mnt/tmp: No such device

although the device is seen....
