Some configurations may set CTDB_NFS_CALLOUT to the empty string. They may do this if they allow a choice of NFS implementations. In this case the default call-out for Linux kernel NFS should be used. However, statd-callout does not call nfs_callout_init() to set the default. Therefore, statd-callout is unable to restart the lock manager, so the grace period is never entered. statd-callout must call nfs_callout_init() before trying to restart the lock manager. BUG: https://bugzilla.samba.org/show_bug.cgi?id=12589 Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com> Autobuild-User(master): Martin Schwenke <martins@samba.org> Autobuild-Date(master): Thu Feb 16 09:21:03 CET 2017 on sn-devel-144
This directory contains run-time support scripts for CTDB.
Selected highlights:
ctdb.init
An initscript for starting ctdbd at boot time.
events.d/
Eventscripts. See events.d/README for more details.
functions
Support functions, sourced by eventscripts and other scripts.
statd-callout
rpc.statd high-availability callout to support lock migration on
failover.
Notes:
* All of these scripts are written in POSIX Bourne shell. Please
avoid bash-isms, including the use of "local" variables (which are
not available in POSIX shell).
* Do not use absolute paths for commands. Unit tests attempt to
replace many commands with stubs and can not do this if commands are
specified with absolute paths. The functions file controls $PATH so
absolute paths should not be required.
