[Linux-cluster] Problem gfs2 and drbd

[Giovanni Mancuso]

Hi to all,
I have a problem with gfs2. If i try to do: watch -n1 'ls -ls /store/'
i have ls: /store/new/: Input/output error
and in my dmesg i have:

GFS2: fsid=sophosha:gfs00.1: warning: assertion "gl->gl_state !=
LM_ST_UNLOCKED" failed
GFS2: fsid=sophosha:gfs00.1:   function = gfs2_glock_drop_th, file =
fs/gfs2/glock.c, line = 963

  =======================

P.S /store/ is my gfs2 filesystem replicaded to another machine with drbd.
