|
|
In a cluster environment using Samba and ctdb it is critical
|
|
that locks on central ctdb-hosted databases like locking.tdb
|
|
are not held for long. With the current Samba architecture
|
|
it happens that Samba takes a lock and while holding that
|
|
lock makes file system calls into the shared cluster file
|
|
system. This option makes Samba warn if it detects that it
|
|
has held locks for the specified number of milliseconds. If
|
|
this happens, <emphasis>smbd</emphasis> will emit a debug level 0
|
|
message into its logs and potentially into syslog. The most likely
|
|
reason for such a log message is that an operation of the cluster
|
|
file system Samba exports is taking longer than expected.
|
|
The messages are meant as a debugging aid for potential
|
|
cluster problems.
