Booting up from a RAID array? Any problems, ever?

See the title Just curious.

Rarely. Almost never.

Only time: Single HD went dead, so boot paused with message about bad drive. Irritating until I replaced the drive.

That's once the OS is installed. Getting the RAID array setup & working can be tricky--depends on controller and drives.

Not really.

It's not very tricky either, but then I've been doing it for a while.

You should really BE concerned when you have problems booting with a RAID-array. That usually means that either you've lost enough drives to fail the array or that somehow the information on it has become corrupted (RAID-information is kept on HD's - they can get corrupted).

But, that's so rare nowadays ... I'd take RAID over "normal" SCSI any day . Esp. when I don't have to pay for it ;D.

Why? Have you got reason to be concerned or are you just considering getting a RAID-array?

had a call from one customer saying his server wouldnt boot, tried to talk him though everything he even replaced the PS, he brought the system in and i found the reason right away. He had 12 SCSI drives in there, all spining up at the same time(or trying to) So i staggered the spin ups and it was fine, so i guess as long as you arn't a moron you should be ok

Wow, 12 SCSI drive spinning up at once... Bet that is why California is having energy problems ATM.

 

[Woodie]

Have to admit, I never thought about that. I just always stagger the startups without thinking about it.

LOL.

Thanks guys, I appreciate the responses. I was just curious...kind of trying to determine what to expect. I will be setting up a RAID 0 array very soon. I have all the parts, just don't have a lot of spare time to actually do it.

I will be making backups (I do that now w/a single IDE drive) on a regular basis so I'm not really worried about losing anything.

I've never played w/RAID before...any words of wisdom? Thanks guys.

I have an IDE RAID at home with two drives doing RAID 0, and I've never had any bootup problems.

 

[MichaelD]

Palpatine,

That's what I wanted to hear! I like it, I like it!

 

[Woodie]

To clarify RAID setup earlier: I was thinking SCSI RAID with hardware. IDE is quite a different beast.

I also was talking SCSI, IDE is usualy easy to set up. really easy, you should be fine.
