Subject: 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

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

Check pg_locks in regards to the table in question.

thanks Igor I did, but not clear what that is telling me, there are 249 rows in there, nothing has a table name , they are all for the PID in the "analyze torque.impressions line that I listed above pid 25765.

Here is one for an exclusive lock, but what should I be looking for? There are no other processes on this box other than slon and this index creation.
