Replace single drive in Mirrored pair & mirror failure notification
I'm doing some testing on mirroring before I copy data to a new VM WHS 2011 I have built. Essentially, I'm checking out how I would be notified and recover from a failed disk in a mirrored set.
So I created 2 vhdx's of the same size, and created a mirrored set in disk management - all goes well. I added a couple of files and check it was all working OK and it was. For my test I removed one of the vhdx's and this came up in disk management immediately (the mirror went red), which was great. However, this was when i identified my first issue: there doesn't appear to be any way for the system to notify me that one of the disks has failed, which is far from ideal.
Question 1: Is there any way for the WHS 2011 to notify me / the admin / users that one of the mirrored disks has failed?
My next step was to try and replace the drive check that the mirror would still be there (to simulate a temporarily failed disk), but when i reattached the vhdx the system did not recognise it as the original half of the mirror.
Question 2: Can WHS 2011 recognise that the disk is part of the previous mirror and carry on?
Either way the third part of the test is to replace the fully failed disk with a new one and ensure WHS 2011 can recreate the original mirror. But when adding a new disk, I can't see how to rebuild the mirrored set.
Question 3: Please can some explain how to rebuild the mirror with a new disk and one of the original disks?
Hp Proliant Microserver And Bare Metal Restore Backup Issues
I've been having some issues recently with my N40L Microserver following a couple of bad sectors being found on the boot drive.
After running check disk and having that mark the bad sectors out of action, I was finally able to use the Windows Server Backup tool in WHS 2011 to create a bare metal restore image and save it to a second physical drive in the box, around 40GB.
I don't have a DVD drive in the server so I made an ISO of the DVD Install disc, and then put that on to a bootable USB stick with the Windows USB / DVD tool from MS. I removed the damaged drive and put in a new blank drive that is twice the size of the damaged one. When I boot the installer dvd on the USB stick, it gets in to the initial screen where it asks you if you want to install a new copy or repair an installation. When I select repair, instantly I receive the error message shown in the attached pic, saying The system cannot find the specified file.
I get no options other than pressing the OK button and it then reboots the server. I remember having issues originally installing it from a USB drive and trying to install on an 80GB SSD - I gave up after a few hours and went with a 60GB HD partition. The install runs now if I select a new installation, it's just the repair option I can't launch.
I double checked the USB stick was fine by creating a new VM on my Mac, and I was able to boot that from USB and select Repair without any problem. I could browse to the network share that contains the BMR image (after replacing the dodgy boot drive back in to get back to windows) and I was able to restore the image successfully. So it seems to me there are issues with the hardware I am running and setup for WHS. It's the HP Proliant Microserver N40L @ 1.5GHz with 8GB RAM, no other changes to the standard box.
Any ideas how to get Repair working?
I managed to clone the dodgy boot drive in the end with clonezilla and so far it's working perfectly with the new drive. It would be good to know I have a proper system backup of the boot drive with a bare metal restore option in the future but until I can get Repair working on the installer dvd this isn't an option. Any suggestions greatly appreciated!
Microserver G7 N54L Port Multipler / Esata Question
Running WHS 2011 on a N54L, it has 2TB, 6TB, 4TB, and 5 TB drives. I have two older 4 bay Mediasonic ProBox enclosures USB enclosures for a total of 8 bays. They have 2TB drives for 7 bays and the 8th bay has a 4TB hard drive that was partitioned into two 2TB drives. I am also running StableBit.
I am adding an 8 bay mediasonic enclosure and I wanted to do it through estata. I am having the problem where it is only recognizing one hard drive in eSATA. No port multipler function. I briefly tried USB and I also could get only one hard drive to show up.
I am finding older directions to flash the bios for microservers before the N54L but nothing more recent. Do I have to flash the BIOS to get eSATA to work with the 8 bay enclosure. Or would it be better to get a PCIe card for eSATA. If so, what PCIe card for eSATA or USB 3 has people gotten to work with the N54L?
The N54L is still under warranty so I have access to the downloads at Hp under the new policy.
Wanted Low Cost Cloud Storage Solution?
Hello! I am looking at a low cost storage solution for my small office. I am a film maker and churn out data bt the TBs. I already have 48 TBs in my office, spread over many 1tb and 2tb drives. Now i am running out of space and also worry about the hard drives failing.
I essentially require storage and archiving. Performance is NOT an important criteria. Often clients require minor alterations to their videos after 1 or even 2 years, so all my files should be accessible. Perhaps i need a Cloud Storage kind of storage, my friend told me about CloudBacko Online Cloud Storage, can i trust this storage.
