commit1c01967116upstream. When a node dies, other live nodes have to choose a new master for an existed lock resource mastered by the dead node. As for ocfs2/dlm implementation, this is done by function - dlm_move_lockres_to_recovery_list which marks those lock rsources as DLM_LOCK_RES_RECOVERING and manages them via a list from which DLM changes lock resource's master later. So without invoking dlm_move_lockres_to_recovery_list, no master will be choosed after dlm recovery accomplishment since no lock resource can be found through ::resource list. What's worse is that if DLM_LOCK_RES_RECOVERING is not marked for lock resources mastered a dead node, it will break up synchronization among nodes. So invoke dlm_move_lockres_to_recovery_list again. Fixs: 'commitee8f7fcbe6("ocfs2/dlm: continue to purge recovery lockres when recovery master goes down")' Link: http://lkml.kernel.org/r/63ADC13FD55D6546B7DECE290D39E373CED6E0F9@H3CMLB14-EX.srv.huawei-3com.com Signed-off-by: Changwei Ge <ge.changwei@h3c.com> Reported-by: Vitaly Mayatskih <v.mayatskih@gmail.com> Tested-by: Vitaly Mayatskikh <v.mayatskih@gmail.com> Cc: Mark Fasheh <mfasheh@versity.com> Cc: Joel Becker <jlbec@evilplan.org> Cc: Junxiao Bi <junxiao.bi@oracle.com> Cc: Joseph Qi <jiangqi903@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
