[Ocfs2-users] Number of Nodes defined

[David]

Sunil, et al,

The reason I needed to make this changed was because the ocfs2 
partition, which is 101G in size with 41G currently in use ran out of 
disk space even though the OS was reporting 60G available.

I had this issue once before and found that the node slot of that 
cluster was set to 4 even though there were only 2 nodes in the 
cluster.  When i reduced the node slots to 2 disk space was freed up.

I made these changes to this cluster; reduced the node slots to 2 and 
everything worked until this morning when the same error returned "No 
space left on device".

The OS is still showing available disk space but as the error suggests i 
can't write to the partition.

Any idea what could be happening?
