I apologize if my questions are too basic for the list. I am new to
Redhat implementation in production environment. I am in proccess of
impletmenting Redhat ES 2.1 and Redhat AS 2.1.. My background is solaris.
1. How does most people manage root file systems in linux production
environment? I have two JBOD scsi disks for root file systems. I
already install the OS on one disk. I just need to mirror the OS disk
to the other disk. Do I use raidtool? or do I use LVM to mirror? How
does raidtool and LVM work together? Or does LVM have RAID 0, 1, 5
capability also? What is the easiest/best setup for 24/7 production
2. I need to have LVM support for data disks, does ES 2.1 or AS 2.1
come with LVM? If not how difficult is it to implement it. Is it
recommended with ES 2.1 or AS 2.1? Your reccomendation?
4. How do people do this in production if you have to mass install
identical systems with Root file systems using Software RAID or LVM?
Will Ghost/DD do the job? Any reccomdation?
3. I need to have mulitiple nodes see the same file systems through the
SAN impletmentation. I read about Sistina's GFS. Is this product
similar to Veritas SanPoint foundation suite where multiple nodes can
see same file systems. How much does GFS cost for, say for 2 cpu's, 4
- 6 nodes? Are there other products that does similiar job?
Thank you for your help!
