Hi, After upgrading ocfs2 my cluster is instable. At least ones per week I can see: kernel panic: Null pointer dereference at 00048 o2dlm_blocking_ast_wrapper + 0x8/0x20 [ocfs2_stack_o2cb] stack: dlm_do_local_bast [ocfs2_dlm] dlm_lookup_lockers [ocfs2_dlm] dlm_proxy_ast_handler add_timer ..
After that sometimes deadlock happens on another nodes. Entire cluster restart solve the issue. I see in log: (dlm_thread,7227,3):dlm_send_proxy_ast_msg:484 ERROR: ECB9442E19A94EAC896641BFADD55E4B: res M0000000000000001f411c900000000, error -107 send AST to node 4 (dlm_thread,7227,3):dlm_flush_asts:605 ERROR: status = -107 o2net: No connection established with node 4 after 10.0 seconds, giving up. o2net: No connection established with node 4 after 10.0 seconds, giving up. o2net: No connection established with node 4 after 10.0 seconds, giving up.

Which feature ? Thanks for any help Pawel _______________________________________________ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com https://oss.oracle.com/mailman/listinfo/ocfs2-users
