Hi I'm experiencing the following problem while using OCFS2 over DRBD partition. My config is the following: 2 servers with pacemaker+corosync stack configured Debian Lenny/Squeeze mixed: kernel - linux-image-2.6.32-bpo.5-amd64 (2.6.32-26~bpo50+1) kernel modules - drbd = 8.3.7 (api:88/proto:86-91) ocfs2 = 1.5.0 packages: pacemaker = 1.0.9.1 corosync = 1.2.1-2 dlm-pcmk = 3.0.12-2 ocfs2-tools-pacemaker(contains ocfs2_controld.pcmk binary )=1.4.4-3 ocfs2-tools = 1.4.4-3 Kernel trace follows here: [ 3128.804789] block drbd0: Handshake successful: Agreed network protocol version 91 [ 3128.805094] block drbd0: Peer authenticated using 20 bytes of 'sha1' HMAC [ 3128.805176] block drbd0: conn( WFConnection -> WFReportParams ) [ 3128.805274] block drbd0: Starting asender thread (from drbd0_receiver [4776]) [ 3128.805533] block drbd0: data-integrity-alg: <not-used> [ 3128.805626] block drbd0: drbd_sync_handshake: [ 3128.805695] block drbd0: self B4F22E41814A97AB:ADC1DEC415E06ACD:0E1A98B5C70EAE0E:578A64518662F9CF bits:202 flags:0 [ 3128.805788] block drbd0: peer ADC1DEC415E06ACC:0000000000000000:0E1A98B5C70EAE0E:578A64518662F9CF bits:0 flags:0 [ 3128.805880] block drbd0: uuid_compare()=1 by rule 70 [ 3128.805953] block drbd0: peer( Unknown -> Secondary ) conn( WFReportParams -> WFBitMapS ) [ 3129.365716] block drbd0: conn( WFBitMapS -> SyncSource ) pdsk( Outdated -> Inconsistent ) [ 3129.365816] block drbd0: Began resync as SyncSource (will sync 808 KB [202 bits set]).
