I have an Oracle 9i database server with Fedora Core 3 on an IBM xSeries 445 server. This server has two QLogic QLA2312 fibre channel adapters which connects it to a SAN. The database is working great and it's up and running for 57 days so far under heavy load.
The SAN partition where the Oracle datafiles resides is getting full (96%) and I need to create a new block device and "present" it to the server so I can format it (ext3) and use it to extend the database table spaces. How do I do that without rebooting the server?
In the same way, how do I remove the block device without rebooting the server and compromising system stability? I mean, I can umount the unused SAN partition but how do I remove that device from the OS so that it can't be mounted again?.
I need this because the server is used for a critical mission web application, besides, I dont want to lose my uptime.
I hope you can help me... thanx.
