Admin team,
We are upgrading from Postgres 7.4.5 to 8.2.5 in mid January. We are also
adding new disks
As we go. I am investigating using the new tablespace facility to move our
biggest and most accessed
Table to the new disk. Here are the statistics. We are running RAID 10
Current database size ------------- 63 GIG
Heavy accessed table to move:
Table ----------------------- 7.4 GIG
2 indexes ------------------- 3 GIG apiece
2 other indexes ------------- 2.5 GIG apiece
Current database disk configuration
TOTAL space -------------- 404 GIG
TOTAL spindles ----------- 3
TOTAL mirrors ------------ 3
New additional disk configuration
TOTAL space ------------ 290 GIG
TOTAL spindles ----------- 2
TOTAL mirrors ----------- 2
The choices we see are:
1. Adding the two new spindles to the other three making one huge
logical partition
And all 350+ tables and 400+ indexes continue to reside there
2. Keeping the two new spindles separate and dedicating the heavy access
table
And its 4 indexes to it.
3. Keeping the two new spindles separate and dedicating the heavy access
table
To it, but keeping the 4 indexes on the old partition.
I know that maintaining almost 700 GIG of total disk space being utilized by
a 63 GIG
Database looks like disk-space overkill but we do expect massive growth
over the
Next 2 - 3 years.
Any thoughts / comments would be appreciated.
Also are there tools out there that monitor disk I/O and disk speed?
Thanks for your time,
