windows – Import a single Raid1 disc and use it as a drive

I had an Intel raid1 disk array (3 TB each) and I had to rebuild the system. Now I have both disks, but I don't really need a raid anymore because I'm just planning to use Backblaze to back up my data on the PC. After attaching the disks, they appear as "Disk0 Dynamic Foreign" and "Disk1 Dynamic Foreign".

The only options in Windows Disk Manager are "import a foreign disk" and "Convert to basic disk".

After googling for a while, I run out of solutions, what is the best way to make these disks usable by Windows 10?

migration – Storcli – migrate from RAID1 to RAID10

I have a system with two hard drives configured in RAID1. I bought two more – same model / size, etc. – and now I want to reconfigure them in RAID10.

I have storcli installed in VMWare and works, but I can't find anything on the conversion to raid10, just raid5 / 6 …

I only found how to create raid10 from scratch:
storcli -CfgSpanAdd -r10 -Array0[64:0,64:1] -Array1[64:2,64:3] -a0

But nothing on how to migrate the existing array from two disks to four.

Of course, I would like to keep the existing data.

Ideas?

raid1 – What would you call this "RAID"? RAID 1 + 6?

I have Snapraid running as a RAID6 snapshot (2 parity disks) for my 9 disk array which calculates a new parity once a day. Next, I have Drivepool duplicate some very important folders on the array on all real-time data disks like in RAID1.

Would it still be considered RAID1 + 6 even if it is a real-time / instant hybrid array or is there a different name?

RAID – New 2x SATA 12 TB drives, failed during RAID1 initialization, S.M.A.R.T. Fault

I recently installed a machine with Threadripper 3960X and Zenith II. I bought two 12 TB Seagate drives (Barracuda Pro) with the intention of configuring them in RAID1 using the integrated RAID on the motherboard.

Now, I first configured it using the BIOS and booted into Windows, ran AMD RAIDXpert2 and after a few hours I noticed that it was stuck at 1.2% when of initialization. I waited a few more hours, but it was still there, so I stopped, pulled the bay out, and started again. In short, the next 2 tests turned out to be similar, with a different completion percentage – I left it over the weekend and saw Status: FAILURE in RAIDXpert2.

Restarted, the BIOS informed me of S.M.A.R.T. problems on one of the discs. The same thing appears on CrystalDiskInfo. I believe I should RMA the disk, but since this is the first time I configure RAID, did I do something wrong and it was my fault at some point?

After all I noticed, the disks were configured with random partitions of the same size. Is this the aftereffect of the initialization process? Do you have any advice on how to configure RAID1 so that it is visible without problems on a dual boot system with Linux?

Error summary for CrystalDiskInfo S.M.A.R.T

raid – Sun X4100 inactive raid1 bay repeated

I know a blade marked EOL 2008 needs to retire, but since management doesn't care, we are forced to keep using it.

This SunFire X4100 RAID1 blade repeatedly appears to be inactive … using the LSI utility menu, we defined it as active and waited until synchronization went to 100% and optimal 3 times in 4 days … yet, for the 4th time, she became active again …

Any suggestions, in addition to replacing the blade immediately?
Will the complete power off, ejection of the 2 discs and their placement on another identical x4100 less used and used, save us time until the management realizes the imminent death?

Thank you.

hp proliant – How to replace a failed drive in the HP RAID1 + 0 ADM configuration

We have an HP DL380p Gen8 server configured in RAID1 + 0 ADM mode as follows:

  • 6 1TB hard drives for RAID
  • 2x 1TB hard drives as cold spares

According to HP, Advanced Data Mirroring (ADM) is their implementation of 3-way mirroring, in which the third set is used as a hot spare. One of the member drives is down and the hot spare has been activated, resulting in a rebuild. Even if the rebuild is complete, hpacucli always lists the array and logical drive elements as having a failed physical drive.

How to clear this state and make the hot spare active (2I: 2: 7) become a member of the mirroring group to replace the actual failed drive (2I: 2: 5)?

linux – mount an external hard drive after zeroing the raid1

I have 2 external hard drives, which were in a raid 1. No operating system, only data. I've removed the superblock from one of them using mdadm --zero-superblock /dev/sdb1 in order to get rid of raid1. Now I can not mount it:

# sudo mount /dev/sdb /mnt
NTFS signature is missing.
Failed to mount '/dev/sdb': Das Argument ist ungültig
The device '/dev/sdb' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a

Attention to nocix.net: impossible to solve a problem of hard disk in RAID1

Hello,

Today I have received a letter

This is a mail message automatically generated by mdadm
run on

A DegradedArray event has been detected on the md / dev / md1 device.

Faithfully to you, etc.

P.S. The file / proc / mdstat currently contains the following elements:

Personalities: (raid1)
md1: active raid1 sdb2 (1)
952053568 super blocks 1.1 (2/1) (_U)
bitmap: 8/8 pages (32 KB), piece of 65536 KB

md0: active raid1 sdc1 (0) sdb1 (1)
24559488 super blocks 1.1 (2/2) (UU)

unused devices:

Then I contacted the support.

They said that the hard drive needs to be replaced.

I asked them to replace him and I received an answer:

We do not treat raid boards, it's up to you to do it.

I said that

Raid was installed by your staff when configuring the server.

And received an answer

We only installed it and then we handed it to you. By acting as totally unmanaged services, all software aspects are managed by you, the customer.

I asked them

Before removing a server to check the hard drive:

Personalities: (raid1)
md1: active raid1 sdb2 (1)
952053568 super blocks 1.1 (2/1) (_U)
bitmap: 8/8 pages (32 KB), piece of 65536 KB

md0: active raid1 sdc1 (0) sdb1 (1)
24559488 super blocks 1.1 (2/2) (UU)

After checking the hard drive:
Personalities: (raid1)
md1: active raid1 sdc2 (1)
952053568 super blocks 1.1 (2/1) (_U)
bitmap: 8/8 pages (32 KB), piece of 65536 KB

md0: active raid1 sdb1 (0) sdc1 (1)
24559488 super blocks 1.1 (2/2) (UU)

Why
sdb2
has changed to
sdc2

And
sdb1
has changed to
sdc1
?

And received

I think that's how the records were labeled. The failed drive is the drive with the Z2UV5AZUS serial number and a physical label that matches drive 2. As such, I placed it as the second drive on the server.

After rebooting, the server went into emergency maintenance and read – only shell mode.
I have received:

It seems that the operating system is read-only, I can not do anything to edit or display ssh for you.
Even when connected, I can not edit anything or begin, it is read-only. We can reload the SSD on centOS 6 if you wish or give you a KVM.

I asked them to reload centOS + cpanel

I received

Please note that it's up to you to install cpanel.

I asked

Cpanel has been installed previously by your staff.

I received

We do not install third-party applications. We can provide you with a link on how to install it.

The problem is still not solved.
I will restore backup data to another server.
I asked for a refund. The server was prepaid for 6 months (the server configuration was done on 2014-06-29).

Thank you.

Get data from the Raid1 drive

Get data from the Raid1 drive

Hello.
I have a dedicated server of soyoustart. So I used virtualizor on the dedicated server to split it into kvm vps. On a KVM vps, I have installed cpanel. yesterday I reinstall the operating system on this vps, so that all the data has been erased. unfortunately, a mysql database that I exported before reinstalling the operating system was corrupted. Now I really need this database. is there a way to get this mysql database from the main RAID server or anyway? here is some information from my dedicated server that might help you:
