Hello everyone-
I'll cut right to the chase here. One of the disks in my RAID 0 array is showing bad sectors and is making bad noises. I believe that both disks are still in warranty, so I'm hoping to just get with the manufacturer and replace them(either of my laptop or of the disks, if MSI tells me to stuff it up my a-hh-- bum).
Basically I have two identical hard disks that are in perfect working order, they just don't have the vibration tolerance they need for the environment they are in. (I am making an educated guess that this is the cause). The disks are in RAID 1 configuration via md raid/linux software raid.
Need to recover data from raid1 component disk using ubuntu live usb disk. The existing software raid was broken. After many attempts, I removed degraded raid setup from BIOS but ubuntu live could not detect filesystem on any of the two component disks.
disk utility says "raid component disk" in one of the disks.
gparted does not report filesystem in any disks.
Please suggest.
Currently, I have 4 hard disks which have been configured as RAID 1+0 in HP Proliant 380 G7, SmartArray p410i. I am planning to buy other new 8 hard disks to replace old array by swapping the disks out and keep the old array as backup. I also make full backup and I will use this backup to restore to new 8 hard disk array.
I have installed FreeNAS on a test server, with 3x 1Tb drives. They are setup in raidz. I tried to offline one of the disks (from the FreeNAS web-ui), and the array became degraded, as I think it should.
The problem is with the array becoming unaccessible after that. I thought a raid like that should be able to run fine with one of the disks missing.
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 GIGABYTE motherboard GA-P35-DS3 with onboard RAID-1 controller. When I replace one disk, how does the RAID controller detects that there is an empty disk, that has to be filled with the old data?
I want to install newer disk with a higher capacity. Can I use a disk image tool like Acronis to copy the disk content from one of the old disks to the new harddisk?
I originally setup a CentOS 6.2 server on two 500GB disks as a RAID 1 array from the install. One of the disks has been removed and I am now running the system on the remaining disk as a degraded a... [by RikT]
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?
