Well, using both RAID1 and RAID0 (RAID10) would be faster then just RAID1, but that requires a minimum of 4 drives. Unless you wish to purchase more drives. Stick with RAID1 which gives mirroring but no performance boost.

I wouldn't be surprised at all if it turns out that the new front fan that is directly attached to the drive cage, introduces vibration through the metal drive cage to the drives sharing it. Possibly that vibration is giving you the issues. It would be a new one - but...

Deltik, you've misunderstood how Linux Software RAID (md) works. md makes a virtual block device out of multiple devices or partitions and has no awareness of what data you are transferring to and from the virtual device. You hoped that it could do things that it wasn't designed to do. Answers 1. Why doesn't md fail the unresponsive drive/partition? ...

After spending all day on chat with HP for the same issue, this is what worked: 1) Boot the server into Intelligent Provisioning using F10, with no other DVDs or USB drives attached. 2) Once IP has come up asking whether you'd like to run diagnostics or install your OS, open an ILO Remote Console and add your SLES ISO as a virtual drive -> Image File ...

Ok, folks, i tried it, and this setup worked: 2 320gb SATA HDs in Raid 0/1/5/10 (Intel Matrix Storage Manager (the newer name for this is Intel Rapid Storage Technique) => this is a BIOS RAID! (CPU is still used!) with an additional SSD on the third connector of the Intel ICH10R Serial ATA connectors on NON-RAID mode So it is no problem to attach non-raid ...

Have you RTFM'd? https://www.asus.com/Motherboards/P6T7_WS_SuperComputer/HelpDesk_Manual/ On page 4-46 it states that the ICH10R only supports 4 disks in RAID mode - The utility supports maximum four hard disk drives for RAID configuration On page 4-50 it states that the SAS controller only supports 2 SAS disks Install two internal SAS hard ...

I've seen similar cases where the start of a filesystem was mistakenly overwritten. Recovery is sometimes possible by mounting the filesystem with a backup superblock.

It appears that the Mediasonic is now presenting the drives as four independant disks as it's asking you to format four times. I would agree with Harrymc but add R-Studio and UFSexplorer as other popular RAID recovery tools. Also you may want to check the SMART status of the drives using a tool like CrystalDiskInfo. You may be dealing with failing drives ...

Debian will install and boot just fine on a GPT partitioned disk in a BIOS booting system. All it requires is a 1 mb bios_grub partition.

You shouldn't have to - looking at the specs for the microserver, it probably has UEFI (it's a semi-modern core i3 or i5 - and those have never come with bios). It might have an 'old school' text interface for the bios but that's fine. The system apparently officially supports 4tb drives anyway. If you wanted to do an exotic boot, and wanted a seperate ...

Yes, GPT works fine with most BIOSes – as the BIOS boot process really only involves running the bootcode in sector 0, and it's up to that bootcode to actually interpret whatever partition table it needs. (For example, syslinux has separate MBR & GPT versions of the bootcode, and LILO just hardcodes the offsets instead.) Similarly, it's up to the ...

Whatever you do, do not write anything to the disks, and certainly do not format them ! If all the disks have become unrecognizable at once, my first guess would be that the Mediasonic enclosure is broken. Your only hope is that while breaking down it did not destroy the disks. For lack of information about your computer, here is the general direction I ...

Try grabbing the newest one from here. https://downloadcenter.intel.com/search?keyword=ESRT2 or more specifically https://downloadcenter.intel.com/download/24636/ESRT2-RAID-driver-for-Linux- There is an rpm version as well as the .img DUD file try both. I've had trouble installing for different kernel versions but give that a try. Hope that helps!

Yes, it is possible to convert from RAID-1 to RAID-5 or (better RAID-6). I have converted single btrfs filesystems (one drive) to RAID-1, then to RAID-5 and to RAID-6. However, as useless as this may sound to some people who are used to other technologies that do not offer this feature (after all, why would anyone keep converting raid levels back and ...

The 6405E is not fast enough for SSDs. Almost all SSDs have IOP capability that will outrun a 6405E. It's a case of balance - buying fast drives means buying a fast RAID controller. Look at the 71605E for SSD RAID 0,1,10 functionality. N

I made sure that the first depicted partition was written as Primary, but was unable to verify the correctness in Ubuntu, even after installing all hfs packages i could find on short notice, adding "hfs" and "hfsplus" to /etc/modules, using sudo fsck.hfsplus -f /dev/sdb1, and rebooting multiple times: vagrant@vagrant-ubuntu-trusty-64:~$ sudo mount -o force ...

Boot into your BIOS and and make sure onboard RAID is enabled. Perhaps you disabled it by accident? Its highly unlikely that changing graphics cards would cause the issue. If it is disabled, enable it - obviously. If it enabled, it is possible the graphics card's BIOS could prevent you from seeing it... still not likely, but replace the card to be sure.
