Hi, after some time of successfull stress-testing I got an I/O-error after some time and the following message in the system log: GFS: fsid=Isabella:301bis304.3: fatal: invalid metadata block GFS: fsid=Isabella:301bis304.3: bh = 39254347 (type: exp=4, found=0) GFS: fsid=Isabella:301bis304.3: function = gfs_get_meta_buffer GFS: fsid=Isabella:301bis304.3: file = /usr/src/packages/BUILD/cluster-cvs.STABLE/gfs-kernel/src/gfs/dio.c, line = 1223 GFS: fsid=Isabella:301bis304.3: time = 1139576449 GFS: fsid=Isabella:301bis304.3: about to withdraw from the cluster GFS: fsid=Isabella:301bis304.3: waiting for outstanding I/O GFS: fsid=Isabella:301bis304.3: telling LM to withdraw lock_dlm: withdraw abandoned memory GFS: fsid=Isabella:301bis304.3: withdrawn gfs_fsck was able to correct this error. My "playground"-config is probably rather unusual *g* (I'm trying to use spare disks in cluster nodes to emulate a SAN): - 4 nodes of a cluster export spare disks via iSCSI (ietd) - 8 nodes (the 4 ietd-nodes included) import the iSCSI-targets with open-iscsi (v. 1.0-485) (nodes do not import their own exported disks) - the four local/imported disks form a LVM volume-group with a single large logical volume with GFS/lock_dlm/clvmd Is clock-syncronization important? What caused this error? Are there any experiences with iSCSI+Linux Software RAID (Level 1)+GFS? -- Michael Weitzel -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
