[Linux-cluster] gfs_fsck problem

Hello --
I am having trouble fscking (running gfs_fsck) on gfs filesystems. I have
a two node cluster that is going to be used as file servers. I recently
noticed that I could not fsck the gfs filesystem they share. Initially I
thought this was due to some problem with my hardware, but when
I tried creating a new gfs filesystem, then immediately fsck-ing it, I
still have problems, and the fsck is unable to complete. The storage
system appears to work fine with other file systems.
I am using the "RHEL4 branch", current as of this morning.
Does anyone have any advice as to what I might be doing wrong?
Here is what I was trying:
[root at mugen gfs]# gfs_mkfs -V
gfs_mkfs DEVEL.1116516970 (built May 19 2005 11:37:18)

[root at mugen gfs]# gfs_mkfs -j 3 -p lock_dlm -t ftp:dds_space
/dev/mapper/ftp_space-erc1
This will destroy any data on /dev/mapper/ftp_space-erc1.
It appears to contain a GFS filesystem.
Are you sure you want to proceed? [y/n] y
