How to determine the progress DBREINDEX
I have executed a reindex on a large table. While I started it during and off peak time, it is nearing a peak time and it is not finished. Is there anyway for me to find out what the progress is on the process so that I can estimate when it will finish? It has been running for approximately 10 hours now.
I do know from my research that if I would cancel it now, it would have to rollback all changes and would most likely take another 10 hours. I am satisfied the best option is to push through, but would like to have an idea of how long that may be.
Would I be able to tell by the size of the database file?

I have another server that has sql 2005 on it. Would I be able to use the dynamic managment views to see anything via a connection from another server?
No, the problem is that the DMVs only report info for 2005 instances...they wouldn't have info for the 2000 machine....

I figured something like that, but I had to ask.
The file for the table being reindexed is usually about 40 GB. I would say that probably 2/3 of that size can be attributed to the table beinig reindexed. Would you say that the file should not grow to more than 80 GB? It is current at about 69 GB.

I mean that 2/3 of the data in the file is in that table with 1/3 being in other tables.
No way for me to be able to tell that....sorry.

Do you have a towel I can use to get the egg off my face? Man, Do I look bad right now. Still running at almost 13 hours and file is still growing.

The reindex ended up take 14 hour 40 mins for a table with 160 Mil rows and 5 indexes.
If I were to reindex it tonight, it should complete relative quick, right?

I would think it would be quicker...but as to how much quicker there is really no way to say.

Please see https://www.experts-exchange.com/questions/23857729/How-to-make-DBReindex-use-multiple-cores.html for additional points.
You can't really tell by the size of the file, other than "a big one will take longer than a small one"...a lot of factors come into play, such as the activity on the server at the time. Does that make sense? Its really not a cut and dry operation.
