* ctdb: Change default debug level to NOTICE (2)Martin Schwenke2015-02-183-5/+3
| | | | | | | | | | | This was true for the daemon until commit b4589b954e1090a934fafd3f8e3c2cf1ed785c61. Defaulting to ERR in the ctdb CLI tool encourages logging notices at ERR level, so default to NOTICE instead.

* ctdb-daemon: Mark tunable VerifyRecoveryLock as obsoleteMartin Schwenke2015-02-132-16/+27
| | | | | | | | | | | | | | | It is pointless having a recovery lock but not sanity checking that it is working. Also, the logic that uses this tunable is confusing. In some places the recovery lock is released unnecessarily because the tunable isn't set. Simplify the logic by assuming that if a recovery lock is specified then it should be verified. Update documentation that references this tunable. Signed-off-by: Martin Schwenke <martin@meltin.net> Reviewed-by: Amitay Isaacs <amitay@gmail.com>

* ctdb-scripts: Fix stack dumping when debugging hung scriptsMartin Schwenke2014-11-181-3/+5
| | | | | | | | | | | | | | | | | There are parentheses missing that stop the default pattern from matching commands with trailing garbage (e.g. "exportfs.orig"). A careful check of POSIX (and running GNU sed with --posix) suggests that "\|" isn't a supported way of specifying alternation in a regular expression. Therefore, it is clearer to switch to extended regular expressions so that this has a chance of being portable (even though the point is to print /proc/<pid>/stack, which only works on Linux).

| | | | | | | | | | | | | | Internally map them to DEBUG_ERR to limit code churn. This reduces the unwieldy number of debug levels used by CTDB. ALERT and CRIT aren't of much use as separate errors, since everything from ERR up should always be logged. In future just ERR can be used.

| | | | | | | | | | | | | | | | | | | | | | | | | Commit 4ee4925d416a86341bd76c11fa99ec9173682a1d forgot about CTDB_NATGW_SLAVE_ONLY so it introduces an incorrect failure when this is set, and CTDB_NATGW_PUBLIC_IFACE or CTDB_NATGW_PUBLIC_IP is unset. Relax the sanity check to see if CTDB_NATGW_SLAVE_ONLY is set. Update the documentation to explicitly state that CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IP are optional and unused if CTDB_NATGW_SLAVE_ONLY is set. It would be possible to insist that CTDB_NATGW_PUBLIC_IFACE and CTDB_NATGW_PUBLIC_IFACE should be unset in that case. However, it is more reasonable to allow consistent configuration across nodes except with some nodes configured slave-only. Add tests, update infrastructure and fix a thinko in the stub's "natgwlist" implementation.
