[Linux-cluster] Can't write to file systems



I am really stumped and could do with some help.

I have a 3 node gfs cluster running gfs 6.1 nad it has started to behave
very strangely after I had some problems earlier today expanding one of the
file systems.  

At the moment all the nodes are in the cluser and it is quorate, and all the
gfs file systems are mounted.  Reading from the gfs file systems works fine
but anything that tries to write to them causes the file system to hang.  

I see a lot of gfs_recoverd and dlm_recoverd processes running.  Do these
have something to do with it?

I'm getting a little desperate to sort this out.  Any help would be gretly
appericated
