I've installed the Open Manage Server Administrator on my Dell T100 to monitor RAID Controller and disks.
From the Physical Controller report web page I see a table listing the two disks I have but under the column "Failure Predicted" I see the capacity in GB!
I currently have a server with 500GB storage (2 physical disks, raid 0) and its already full. I've asked my provider for an upgrade of additional 1TB storage (2 physical, raid 0). These are all hardware based raid.
Almost all files from /usr/local/nginx/html are videos and have consumed the first hard disk raid.
I was switching the disk drives in my server, running RAID 6 on 5 disks on a 3ware 9650SE controller, for newer disks and have run into a problem.
The two first disks went fine, I took out one disk and inserted a new one, let the array rebuild and repeated for disk 2.
When booting after switching the 3.
In one of the answers on SO (I forgot which one) I've seen a suggestion to make a RAID-1 array composed of a RAM disk and a physical partition.
My questions are similar to this thread Does LVM increase the risk of data loss?, however, I couldn't find a satisfying answer.
So the question is, where does LVM store data/files, when I have a Volume Group (VG) of 3 physical disks?
What happens when one disk fails?
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 have to use some physical disk in a Linux machine virtualized with Virtualbox in a Windows 7 host environment but the order of physical disks keeps changing at every reboot and I must reconfigure the virtual machine to match it.
Is there any way I can prevent this?
I have a Windows Server 2003 instance which was once running on physical hardware but now runs on vmware esxi. Disk 0 was once a physical RAID, but is now a vmware virtual hd with a primary partition for the C drive and a second logical drive for the E drive.
Enlarging the VMWare virtual disk is easy, but I'm having trouble extending the E drive.
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.
