Windows 10: Creating storage spaces using 2 drives

I have a workstation (HP z1) that only supports 2 drives. Is it possible to set up a mirrored storage space with this IF the OS (Windows 10) is on a separate partition and I mirror just the remainder of that drive with the other? I know Storage Spaces doesn't support mirroring the boot drive, but I don't know if that applies if the disk is partitioned. My other option is to use the hardware RAID1 built into the motherboard, but I'm curious if this can be done with SS.


Thanks.

How to remove a bad drive in Windows 10 storage spaces pool

Could someone list the steps involved in replacing a bad drive from a Windows 10 storage spaces pool? I cannot find any info on the Microsoft support site that is specific to Windows 10. Also, could you list the steps to remove a 'good' drive and replace
it with another drive if the process is different?

 

Cannot access Storage Space


I've created a problem with Storage Spaces by changing the drive letter in Windows 10. This has caused a Storage Spaces error, and I can no longer see the Storage space in File Explorer.

Disk Management shows the drive as unallocated.

I now have the following situation. The 2 drives in the storage space are the ones shown as 931.5GB (or Disk 4 in the Management image). (it was originally set up as 10Tb but only 2 x 2tb physical disks initially)










Any suggestions as to whether I can correct this. Thanks

Progress Update

I’ve had success but it has not been without a lot of pain and time.

Major issues for me.

• With my first attempts I was NOT able to create a Storage Space. As I research the issue I discovered one post that stated I could NOT have either a software or hardware RAID on the same system. At this time I did have the “LSI SAS9211-8I 8 Port” card installed.
  I’ve discovered that the card was set as a RAID card. At that time I was NOT able to get into the card BIOS and change any of the settings or software, thus I removed the card.
• After removing the card I was able to create the Storage Space but this was not without discover of another issue. I wanted to use Parity which is like RAID 5 and I also wanted to use the ReFS file format. Initially because of my choices (Parity and ReFS)
  I could NOT create the Storage Space and discovered that MS does not support this combination but in the setup they allow you to select Parity and ReFS To resolve the issue I picked Parity and NTFS, this allowed me to create the Storage Space.
• Another challenge was setting the value for maximum size for the storage space. As I understand it is best to establish a huge max size thus as you add more disk you do not hit the max size limit. If you hit the max size limit then it will be necessary
  to create a new storage space with a huge max size, move the contents of the first storage space to the new storage space. This would be super time consuming and require a lot of hard drives as temp holding space. After many attempts I settled on a max size
  of 50TB and with the three drives, 1-3TB, 1-4TB, 1-6TB, I had a space with 11.8TB and a max size of 50TB. This should be more than enough space for my data for the living years I have left remaining.
  
  
  
  

Thus I finally had a workable storage space and my next step was to copy my “data” files to the new storage space so I kicked off all the necessary copy actions to copy the data. I used the high-level folder as my starting point. Following are two images
showing the action. As you can see some have completed and some have a VERY long time remaining, e.g. 1913 minutes = 231 hours or about 10 days. I realize that all the copy actions are using the same drives thus this is a performance hit but it is a lot faster
than me running one copy at a time thus forcing me to start another copy when one completed. But the actual performance hit is less than the time I would lose by the time gap between a copy finishing and me starting another copy. However there does seem to
be a huge performance overhead with Storage Spaces. Originally I had to move the contents of the three drives in the Storage Space and if I recall this was completed in less than 4 days.









After the copy to the storage space completes I see the following as the next steps.

• Share the storage space with full privileges so all my other PCs can access the drives. This is quick task and should take less than 10 minutes.
• Test to ensure all PCs can access the storage space. This is a bit more time and should take 1-2 hours.
• Change ALL applications on ALL PCs to use the new storage space and confirm that all is working correctly. This could easily take a couple of days.
• Use Hard Disk Sentinel (HDS) to reinitialize disk surface. This is an extensive test and will take about four days to test both drives being freed up, e.g. the 4TB and 6TB that currently have my data on them.
• The HDS 4TB drive test will finish at least a day or two before the 6TB completes, when it does I could add it to the existing Storage pool or just wait until the 6TB HDS completes and add it to the storage pool. If I wait for the 6TB drive this would give
  me a bit over 17TB for my data. I feel that this will be more than enough to last me for whatever years I have left.

At the same time I’m doing the above I can also work on the LSI SAS9211-8I 8 Port card and get it working, this will be for all of my backups. I have contacted LSI support via email and they did send information. Some of the info I was able to implement
and others presented a problem for me. I sent a follow-up email last night but most likely will not get an answer until Monday. I was expecting a reply but so far no reply.

After I get the card working I can create another parity storage space for all of my backups. Currently I have five drives connected to the card, 2-1TB drives, 1-1.5TB drive, 2-2TB drives.

After I create the backup storage space, setup full permissions so all systems can access and confirm the access, the following steps will be performed. These will take several days or weeks.

• Copy data from one backup drive. I currently have as backup drives, 2-2TB, 7-3TB, 3-6TB, to the temp drives attached to the card. I will start with a 3TB drive. By starting with a 3TB drive this will ensure I can replace one of the 1TB drives without space
  issues on the storage space. When I complete the backup storage space build it will have the 3-6TB drives and 2 or 3 3TB drives assigned to the space. This will provide between 23-26TB of storage for backups. If I need more space I can purchase a 10TB drive
  and replace one of the 3TB drives. Thus I’m playing a lot of musical chairs to get to the final build.
• Confirm that all the backup data has been removed from the drive to the backup storage space
• Change the necessary applications to use the backup storage space.
• Confirm that apps are successfully using the backup storage space.
• After the copy completes run the HDS test on the old drive. BTW the test level I’m using wipes out any data on the disk

After the HDS test completes remove the smallest drive from the backup storage space and add the drive that just completed the HDS test
