is it possible to expand an existing array?
remove comment, misread
you want to add a disk to the array?
i imagine that'd be pretty simple in the raid setup.
are you talking about increasing the partition on the raid?
have three drives in the array now and i want to add another.
I don't know. I couldn't figure out how. I just did a backup of everything and rebuilt it
i just recently upgraded the RAID at my work and in the bios RAID software there was a setting that said "add disk to array". so if it's as simple as it was stated there then it shouldn't be too hard..
although i was replacing both disks with larger disks to increase the size of the partition that was on the raid. in order to do that i had to delete the array and recreate it, although the data remained present. although i backed up just in case because it was the first time i had done it
And it was using a Perc 5/i? I know its possible on my ARC-1220, but didn't see anything in the Perc 5/i bios.
no, it wasn't. that's why i'm not sure for this dudes situation. but it seems like it'd be a pretty important feature for any RAID controller, imo.
thinking about pulling a fail move.
think my web host would flip if i uploaded 1tb of stuff then re-downloaded it?
or should i go to frys and just buy/return an external drive?
my options are limited.
i bet hostgator calls me
I don't know about your upload speeds, but that would take forever for me. Worth it to get the external.
think i will hit frys tomorrow.
Have a Perc 5/i here, recently added another 1TB disk to an existing 3 disk RAID-5. Piece of cake, took about 30 hours I think, then had to extend the GPT partition in Windows.
shit forgot about the GPT. Is there anyway to convert from MBR to GPT? ~1.7TB currently, and more and I am over. Good to know you are able to add easily. I must have been blind
you recall how you did it?
Just added the drive to the controller, booted up, and used the MegaRAID Storage Manager Reconstruction Wizard.
It will ask you to confirm that you have your data backed up (you should as a best practice, but the array reconfiguration is not destructive).
Shit, scratch that. I just read through the MS document and others and looks like there isn't a way to do it that doesn't involve trashing existing partitions.
went to frys and got ANOTHER 1tb drive to fix the problem.
how many drives can i run off a 500~600w power supply?
depends on the rest of the system. But if it is just a shitty system... More than you'll have connections for. HDDs don't take a lot of power except for power up. And most good controllers stagger driver power up.
system looks like this (media server):
Asus M2N-E mobo
AMD dual core proc
four 1tb drives connected to the perc
one 120gb OS drive connected to mobo
256mb pci video card
