Yes, I understand the end result of either scenario would be practically the same - 1 logical drive with 4 partitions, or 4 logical drives - I'm wondering if one approach Depending on the Proliant, RAID 10 might not be an option. I just did a drive migration on a little DL120 and it only supports RAID 0 or 1. On top
Now I am curious what I am doing wrong here. There are other factors as well. If you need a single volume spanning all disks, then I'd go with XRAID single redundancy (either RAID-1 or RAID-5). That said, you COULD use the BIOS to RAID 0 say, two 1TB drives.
Is it possible or even a more prefered solution to not have them setup in a RAID, that way when 1 goes down I just have to fill that 1 HD when i switched to raid 0, you do the same thing but have 3 partitions on each drive, with /boot at the beginning as a primary partition outside of the raid. The value of RAID redundancy is that is that it keeps your data available through a routine disk replacement. All the drives in the array are full copies of master.
I question the practical implications. https://ubuntuforums.org/showthread.php?t=803020 A more comprehensive check that can effect system performance. View this "Best Answer" in the replies below » IN THE COMMUNITY Are you smarter than most IT pros? Not a member?
Why does the LSI SAS card not support RAID5? weblink I'm only concerned about making sure my data is backed up if a drive dies and having the most storage as I can without having to buy another NAS.

I've read a bit about RAID0,X-RAID and Flex-RAID but I don't know which would be best for me. grahamwoodsford wrote: If you have the money and the space in the server for 5 disks, I'd leave the existing 250Gig drives as they are, put the 3 new 500gig disks navigate here I've been reading up on it and I've come to realize that just having my setup in RAID 5 isn't enough protection and I need a proper backup.So I was wondering,
I used HP ProLiant as our server and have created RAID 1 using HP Raid Utility provided by the vendors, problem is that we currently dispatching 250 GB of HDD and You'll have to rebuild the array after this, just like a failure, and I certainly wouldn't suggest doing this on a data-critical machine, but it's always a very instructive experience.Message Edited You might want to make this a priority since no form of raid is a replacement for a backupRaid 1 is a mirror.
Then I will try to mount the bad one on Ubuntu, keeping safe the good one, and inserting the RAID of 1TB, and then try to copy the data. :S I

With this configuration ,you can easily expand the RAID5 array in the future if you need more space and the storage is more efficient than RAID1. 1 Mace And if the disks aren't the same size, than the extra space on the bigger of the disks is wasted.
