Re: Slow table update on new server 11.50.FC9

Posted By: LARRY SORENSEN

In Response To: RE: Slow table update on new server 11.50.FC9 (Everett Mills)

It is set up exactly the same as the server the data archive came from.

It is on RAID 5, only because the external disk array, array manager, had a limited selection of possible RAID configurations. RAID 10 is not one of them. I did choose the disk array. I just had to make things work within the limitations.

Is the disk space on the new server set up optimally for databases? RAID 10,
not RAID 5, no journaling, etc.?
