Subject: [PERFORM] Index creation running now for 14 hours
I'm running 9.3.4 with slon 2.2.3, I did a drop add last night at 9pm, it
started this particular tables index creation at 10:16pm and it's still
running. 1 single core is at 100% (32 core box) and there is almost zero I/O
activity.
CentOS 6.6
16398 | clsdb | 25765 | 10 | postgres | slon.remoteWorkerThread_1 |
10.13.200.232 | | 45712 | 2015-08-25 21:12:01.6
19819-07 | 2015-08-25 21:22:08.68766-07 | 2015-08-25 22:16:03.10099-07 |
2015-08-25 22:16:03.100992-07 | f | active | select "_cls".fini
shTableAfterCopy(143); analyze "torque"."impressions";
I was wondering if there were underlying tools to see how it's progressing, or
if there is anything I can do to bump the performance mid creation? Nothing I
can do really without stopping postgres or slon, but that would start me back
at square one.
Thanks
Tory

Check pg_locks in regards to the table in question.
