I'm a total new to uBuntu... and could use some help...
My iOmega Storcentre NAS crashed because of what appears to have been a Raid controller failure. I've been told that it runs Linux, and the drives are formatted in Ext3. I can no longer access the drives and I do not know the condition of the data on the two 1TB drives (RAID 1), as it may have been corrupted by the controller.
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.
I am working on decommissioning an old server for a client. The server is an older Dell PowerEdge 1600sc with four SCSI drives. Two are stand-alone, and the other two are in RAIDx (not sure the actual RAID id). It does not have an integrated RAID controller (nothing under integrated devices in the BIOS related to RAID), the client has a PowerEdge Expandable RAID controller PCI card for that.
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.
When Ubuntu 9.10 landed, I installed it and saw the partitioner listed my drives in a weird fashion. I have 4 drives in my system - two 500gb drives, two 250gb drives. The 250s appear as nvidia-mapper-device, or something like that. I was told this was fake raid. Since Ubuntu 9.10 gave me a lot of trouble, I used 9.04 and never "fixed" this issue.
Got a RAID question. My PC has 2 identical 500gb HDs. My BIOS setup does not show anything related to RAID, I've checked every entry, every option, yet the 9.10 installer "sees" RAID.
So, is my hardware physically set up as RAID? How can I check? I'd like to have it as 2 separate drives, and screw RAID. What do I do?
A couple of our servers have ST32000641AS (2TB Seagate desktop drives) in RAID 10 using an Adaptec 2405 controller. I've been told by Adaptec that this is a bad idea and we have, in fact, already seen one raid system go down using these drives.
I have software RAID on Ubuntu 10.10 with currently disabled hardware RAID controller, server has 2*500GB in RAID 1 drives for OS and 3TB*4 in RAID 1 for storage. What do i want, create hardware raid at least for storage w/o loosing data, or best option to add two new 3TB drives and create hardware RAID 10.
Can I have software RAID for OS and hardware raid for storage ?
Hi all,
I'm setting up a backup server (yes, I know raid isn't a backup).
I purchased 4 3TB drives, and I was thinking, is there any point to the performance boost Raid 10 gives over Raid 6? All the accesses will be remote, so even with Gigabit ethernet, I'll max out at 125 MB/s (theoretical).
