[ubuntu] Raid 5 array has gone AWOL!

linux-howto

http://ubuntuforums.org – I have a motherboard with an NVIDIA raid controller on it. I used to use it until it became unstable. Constantly showing the status upon POST as "Degraded." So I decided to use the Disk Utility to create a new raid 5 with the same hard drives. I found out that one of the hard drives failed, so I bought another one. After about an hour waiting for it to finish syncing the new drive. Another one failed. I used the disk utility to stop the array and find the problem. Turns out there is one (1) bad sector on another disk. Now I can't do anything. I can't format, I can (Hardware)

Stories similar to [ubuntu] Raid 5 array has gone AWOL!

Hi all,

I am trying to install Hardy server on my whitebox machine, but can't get that far because I cannot create the RAID array I need.

I have a new Adaptec 2410SA hardware RAID card with two new Samsung Spinpoint F3 1TB drives connected to it.

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 have a 5 disk Raid5 array of Western Digital Green (WD10EADS) 1TB. Raid5 is via Windows Server (software raid).

One disk has failed, and it looks as though I can't get the same model replacement. I've also read that the newer (consumer level) WD alternatives will misbehave in a Raid array (TLER issues etc).

The array has been powered up for 29,000 hours (3.2 years).

Hi guys,

I have the following problem. I bought a second ssd for my computer and I'm planning to do a RAID-0 array using my motherboard's built-in raid adapter. On that hard drive I have a windows system and some other partitions apart from Ubuntu.

I have 6 1tb drives in a RAID5. 1 drive went down. On the RAID was 2 virtual machines that I really need back up and running. The spare drive I have to put in the server is a 1.5tb drive, which exceeds the physical per drive limit of the 2020SA. The drive is found in the disk utility, but it is not found in the array management section. I cannot add the drive to the array to have it rebuild.

I'm using a Supermicro X9SRE-3F motherboard with the latest BIOS and 2x 4TB drives connected to the on-board SATA controller.

If I set the BIOS to RAID and create a RAID 1 array, the array shows up in the BIOS as 3.6TB.

I have a raid array of hard drives in a Sun x4600 that need to be moved out, and another Sun x4600 ready to accept those hard drives.

The problem is: in my limited experience with servers, it seems like hard drives added to a server always get wiped by the raid controller because the controller insists on "initializing" drives before recognizing them as a raid array.

Yes, I have backups.

Is it

I have 4 2TB hard drives and I was thinking about using Raid 10. This would give me 4TB correct? My next question is would it be easy to add more hard drives to the raid array. For example if I bought another hard drive can I add it to the array without backing up any data?

Basically I want to be able to start off with 4TB and when the space becomes full add more space as needed.

I have Dell Poweredge T100 server with Dell SAS 6 and two hard disk on RAID 1.

Last week the server died including one RAID 1 hard disk. We sent the server for repair and the problem with PSU was fixed.
