Windows 10: Storage spaces allowable size

I helped a friend set up a 4x20TB JBOD box with storage spaces. PC is Win 11 23H2. I read that the official maximum size of a storage space is 64TB. During setup of storage spaces no complaints or caveats appeared, and in the end we were left with a single 72TB storage spaces volume, which is what I would expect from 80TB of raw disc capacity.Is there any increased risk of instability for this >64TB volume?

Unable to increase size of storage space

Hello, f1sherman

Welcome to the Microsoft community.

I understand that you are experiencing problems with the storage space not changing, you can try the following:

Search for PowerShell in the Start menu and select "Run as administrator"

You can list all storage pools and their associated storage using the following command

Check the size of the storage pool and how much space is allocated. This information can help you determine how much storage space you can expand.

You can use the following command to view the details of a specific storage pool (replace "YourStoragePoolName" with the actual name of the pool):

After determining how much storage you want to expand, use the Resize-VirtualDisk cmdlet. replace "YourStorageSpaceName" with the name of the storage space and specify the new size. For example, to resize a storage space named "MyStorageSpace" to 3TB, use the

Note: Ensure that the specified size is not larger than the available space in the storage pool.



Verify the changes. After resizing, you can verify that the size of the storage space has been updated using the same command you used in step 2.

Remember to back up any important data before changing the storage configuration to avoid data loss.

Storage Spaces not showing increased size..

Hello, Size was increased via storage spaces. I was able to fix the issue. It seems like size increase via storange spaces is not working. I manually have to reboot and then use following command to show the correct size.

C:\ > DISKPART

DISKPART> List Volume

DISKPART> select volume # (this is the number of the volume listed by the above ‘List Volume’ command)

DISKPART> extend filesystem

DISKPART> exit

This fixes the storage pool to show the correct size. But its really annoying to do that every time you increase the size of the pool.

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
