Trying to grow a 15TB file system to 20TB this morning, using RHEL4.4 I got an error and the grow failed. The file system will still mount but when accessed gives the following error and withdraws: Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: fatal: invalid metadata block Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: bh = 465407847 (type: exp=4, found=3) Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: function = gfs_get_meta_buffer Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: file = /builddir/build/BUILD/gfs-kernel-2.6.9-75/smp/src/gfs/dio.c, line = 1223 Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: time = 1201260769 Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: about to withdraw from the cluster Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: waiting for outstanding I/O Jan 25 11:32:49 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: telling LM to withdraw Jan 25 11:32:50 jrmedia-c kernel: lock_dlm: withdraw abandoned memory Jan 25 11:32:50 jrmedia-c kernel: GFS: fsid=alpha_cluster:wav.0: withdrawn A gfs_fsck doesn't work either: Initializing fsck Initializing lists...
