Hi again, I haven't received any answer but I keep on giving details about this issue. Finally I umount GFS filesystem in both nodes and I have done a gfs_fsck;it have fix several filesystem elements. After I have mount it, and when we try to work on previously damaged directories we get those messages: GFS: fsid=hr-pm:gfs01.0: warning: assertion "(gh->gh_flags & LM_FLAG_ANY) || !(tmp_gh->gh_flags & LM_FLAG_ANY)" failed GFS: fsid=hr-pm:gfs01.0: function = add_to_queue GFS: fsid=hr-pm:gfs01.0: file = fs/gfs/glock.c, line = 1420 GFS: fsid=hr-pm:gfs01.0: time = 1237984594 BUG: warning at fs/gfs/util.c:287/gfs_assert_warn_i() (Tainted: P ) [<f9ad7e91>] gfs_assert_warn_i+0x92/0xbd [gfs] [<f9aba680>] gfs_glock_nq+0x131/0x36f [gfs] [<f9aba8d1>] gfs_glock_nq_init+0x13/0x26 [gfs] [<f9acf378>] gfs_private_nopage+0x45/0x81 [gfs] [<c0460831>] __handle_mm_fault+0x23b/0xe08 [<c04597a2>] __do_page_cache_readahead+0x1ab/0x1cc [<c06062fe>] do_page_fault+0x2a4/0x5ad [<c060605a>] do_page_fault+0x0/0x5ad [<c0607dfb>] error_code+0x4f/0x54 [<c060007b>] __inet6_check_established+0x21f/0x394 Any ideas?
