First i build a xen disk image on the local storage fs, then want "cp" this disk image to the gfs2 filesystem. cp disk.img /xenfs/storage1/xenmachine/ this filesystem ( /xenfs/storage1 )is gfs2 with option -j 10, lock_dlm mount option is : noatime,quota=off I have done this sevreal times on one node of my two node cluster, no problem. Yesterday i added another node ( the third ), an on this node the same procedure ended up with this. Oct 4 07:44:15 xen03 kernel: GFS2: fsid=xen:storage1.1: fatal: assertion "x <= length" failed Oct 4 07:44:15 xen03 kernel: GFS2: fsid=xen:storage1.1: function = rgblk_search, file = fs/gfs2/rgrp.c, line = 1116 Oct 4 07:44:15 xen03 kernel: GFS2: fsid=xen:storage1.1: about to withdraw this file system Oct 4 07:44:15 xen03 kernel: GFS2: fsid=xen:storage1.1: telling LM to withdraw Oct 4 07:44:45 xen03 kernel: GFS2: fsid=xen:storage1.1: withdrawn On this node and this gfs2 filesystem the crash is reproduceable. i never tried it on another node, because they are productive. After reboot, the gfs2 can normally be accessed. The same if i try with "dd if=xxx.img of=xxx.img" Any suggestion, where the problem is ? locking, gfs2 options .... -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
