I have a 5-disk Intel RAID 5 along with a 6th boot disk with /, /boot, and swap.
What I was planning to do was mount the Intel RAID partitions (which I've added with fdisk) so that the 6th disk /home, /var, /srv, etc. link to the RAID on the other 5 disks.
Hoping someone can help...
Here is my setup:
4x Western Digital 1TB drives
- 200GB RAID 0 (Windows 7 and Apps / Games)
- 1.8TB RAID 10 (Data)
Both arrays use all 4 disks.
Ubuntu has its own 80GB drive (/dev/sde).
I am trying to setup a raid 5 but when I do the boot block causes the first disk to go to extended when the rest do not have to. This then leaves me with one on extended and three not. That would be fine but then the raid 5 will not recognize the extended so I end up with raid 5 -1 for part of the array. I am thinking that if I could designate 0 to 25 on each disk that all will be well.
I'm trying to install /boot in a RAID 1 using 3 TB disks. As the RAID partition do not let you manage partitions than more than 2 TB, CentOS automatically configures the partitions using GPT.
My current machine (HP Proliant ML110 G4) does not support EFI/GPT so it uses MBR to boot the system.
A friend's machine running Windows XP refused to boot recently which is running 3 SATA disks on RAID 5 (which was previously upgraded from RAID 1 not by me). I have determined there to be a disk failure. The disks have been replaced many times in the past few years. I wish to backup the RAID5 partition before I try anything to fix it.
I know Linux has great capabilities over the years of using it but I can't seem to find an exact name or setup for this scenario. I want to do Matrix RAID (that is not the correct general name but it was as close as I got) on two HDD. I want to put the OS in RAID 1 for redundancy and then have another partition or folder as RAID 0 for TV recordings both on two HDD.
I want to set up software RAID-1 on my Ubuntu system, and found this example of an /etc/raidtab:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
persistent-superblock 1
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
I would however like the path to the raid device to be /raid.
I've currently got a 8GB system disk and two 1TB RAID 1 (software) disks.
Due to a corruption with the 8GB system disk, I'd like to repatition my RAID 1 drive in order to install the OS on this. I'll probally end up making it dual boot Ubuntu and Windows 7.
I have a Debian Linux system (amd64) installed on a RAID-1 system encrypted device (LVM on LUKS) and will have a RAID-6 of >=4 disks where I'll put my data (LUKS and maybe LVM).
I think the basic idea is to unlock the system encrypted partition (at boot at local or via ssh) and to store a keyfile in /etc/crypttab for the RAID-6 encrypted partition. Does that pose a security risk ? I mean ...
