Hi All People,
Merry X'mas
I have some further RAID questions to ask :
1) Can ATA-133 hard drive be used on RAID controller available on market
such RAID 0, 1, 0+1 etc. with cable for ATA100/ATA133. No special designed
controller is needed ?
2) RAID 0

If I said RAID 5 is striping + mirroring, then you're right - I was

Sorry do correct you Ed, but
RAID 5 is not striping + mirroring, it is stripping with distributed
parity,
It is the best compromise when you need fault tolerance, it`s cheaper
then
RAID 1 (mirroring) and the fault tolerance is also ok !
You forgot RAID 4 it is stripping with parity on one Disc !
Thank Ed

Hi All People,
Is RH7.2 coming with software RAID
Can I make 4 (four) partitions in the same hard disc and intall RAID 0 and
RAID 1 to it. Where can I find relevant documentation ?
If I am wrong please correct me
Thanks in advance.

Hi,
I previously had RAID mirroring setup on 2 SCSI hard disks in RH 7.0
Disk #1 died about a week ago, so I put in another drive and did a clean install of 7

You don't. That's as specified in the RAID HOW-TO.

Hi,
I have software raid 1 running on my system, how can i find out
whether the raid is working properly without shutting down my server.
As I know, If there is a raid error, the system will prompt at the
startup time. So , how to find out whether the raid is working fine
without reboot
