Hi! Can anyone explain ? 2 node cluster working. When I remove GFS modules from kernel on one node - get next messages : Sep 10 11:53:26 cl20 gfs: Umount GFS filesystems: succeeded Sep 10 11:53:27 cl20 kernel: CMAN: we are leaving the cluster Sep 10 11:53:28 cl20 gfs: ccsd shutdown succeeded Sep 10 11:53:28 cl20 kernel: slab error in kmem_cache_destroy(): cache `dlm_resdir(s)': Can't free all objects Sep 10 11:53:28 cl20 kernel: [<c013d1d6>] kmem_cache_destroy+0xd0/0x10e Sep 10 11:53:28 cl20 kernel: [<f895c2d5>] dlm_memory_exit+0x37/0x55 [dlm] Sep 10 11:53:28 cl20 kernel: [<f89651ad>] cleanup_module+0x19/0x26 [dlm] Sep 10 11:53:28 cl20 kernel: [<f895c084>] cman_callback+0x0/0x38 [dlm] Sep 10 11:53:28 cl20 kernel: [<c013007a>] sys_delete_module+0x15a/0x193 Sep 10 11:53:28 cl20 kernel: [<c014709c>] do_munmap+0x134/0x184 Sep 10 11:53:28 cl20 kernel: [<c0147131>] sys_munmap+0x45/0x66 Sep 10 11:53:28 cl20 kernel: [<c0105c1d>] sysenter_past_esp+0x52/0x71 what is wrong ?
