** [tickets:#2247] Log stream file is not reserved during si-swap**
**Status:** unassigned

The fix for #2215 introduce a change in log_stream_open_fileinit(). i.e:
- if (stream->numOpeners == 0) {
+ if ((stream->numOpeners == 0) || (*stream->p_fd == -1)) {
This will cause an unexpected behaviour during switchover, I guess.
The reason of it is because numOpeners will be checkpointed between the
activate and the standby one meanwhile p_fd is node locally.
At starting up, both ACTIVE and STANDBY will have numOpeners and p_fd set to 0
and -1 accordingly.
After that, ACTIVE open the stream, increase the numOpeners and sync this value
to standby. Also p_fd on ACTIVE will be set to the opened file but this value
is not checked point to standby.
During switchover, the p_fd of standby will always equal to -1, this cause the
stream filename will always be changed.
This can be easily reproduce by
- create an application stream
- saflogger to write some messages to it
- trigger an si-swap on OpenSAF SI.
- write another log to above application stream.
- Check that the stream filename has been rotated.
