Hey Ubuntu Forums, long time no see.
So i'm trying to set up a RAID, but i'm a bit inexperienced and i'm not sure if the configuration i want to achieve is possible. I was hoping someone more knowledgeable could point me in the right direction.
I have one 2TB and two 1TB drives that i would like to configure in such a way that would be equivalent to two 2TB drives in RAID0.
disks 0 and 1 are raid redundant (OS) and the remaining 6 drives are in raid 5 I believe. i would like to pull out disks 0 and 1 and install new drives to build a new OS. I need to be able to reinsert the old drives and reboot back to the original OS. (swap)
I had a serious problem in the past attempting this.
Computer specs
Intel E8200 Dual Core
MSI G45M MB
Ultra U12-40739 PCI Expansion Card - 2 SATA Internal Ports, 1.5Gbps, RAID 0, 1, JBOD
6 GB DDR2
Q1. I installed Ubuntu 12.04 LTS and Amahi, for using Grey Hole, last night. The two disc on the raid card do not show up under Ubuntu 12.04LTS but they do show up under grey hole so I know the drives and the raid card are working and there.
Afternoon all,
I'm wondering if anyone could point me towards a method to automatically load share files across multiple hard drives? I'm aware I could set up a RAID, JBOD or LVM to accomplish this but unless I went for a mirrored RAID, a single drive failure could mean the end of all my data.
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 have a Proliant ML350 G8 with two SAS raid arrays currently set up - thereby maxing the default P420i raid controller. I need to set up a large video dump space in addition to this existing set-up (for non backed up, non-critical, temporary storage).
I had planned to just add a 2TB SATA disk and plug it into the motherboard.
In Linux, I'm partitioning two disks for RAID1 with fdisk. The first disk partitioning succedes, but the second fail because the raid starts automatically and occupy also the second disk (why? it should have a different UUID).
How to temporary disable RAID autodetect?
Hi guys!
A few days ago, I started upgrading my raid (raid 5) from using 4x1TB to 4x3TB. Never done this before, so it took a while. I replaced the disks one by one and rebuilt the raid in between as I read in some guide. All worked fine, except fdisk complained a little bit about my disks being very large. Didn't think much of it at the time.
I have 22 disks and would like to create a Raid 10. Unfortunately my raid controller (MegaRAID SAS 9260-8i) is only capable to handle 8 arrays within a RAID 10. Because of that I could only use 16 disks in a 2 disks per array configuration.
