No 'Increase Size' Option for RAID 5 Array in RST - Why is this missing?

I have an old RAID 5 array on an ICHR10 chipset that was originally configured with 4 250Gb drives. Over time I've had three of the four drives fail, the most recent of which happened after I'd upgraded the OS to Win8 (note that the boot partition is on an SSD, the RAID array is a separate partition for user data). In the past when I replaced the 250Gb drives with 500Gb drives, I was able to expand the size of the volume in RST, then increase the partition size in Windows Disk Management; however, this option in RST is not available in the last go-around when I replaced a drive that failed with one of larger capacity.

The specifics are this: Array was (2) 500Gb drives and (2) 250Gb drives, with a total indicated space of roughly 700Mb, this being split into two partitions in Windows. I've just replaced a failed 250Gb drive, and allowed RST to rebuild the array, now with (3) 500Gb drives and (1) 250Gb drive. When in RST, under manage, I click on the full Array box, the size is indicated as being 953,899Mb - this is what I expect. And when I click on the old RAID 5 volume on that array, the size is 715,417Mb, same as it was in the past before the last drive failure and replacement.

The issue is that nowhere in the RST interface can I find the option to expand the size of the existing RAID 5 volume; the RST help clearly indicates that I should simply:

1.Under 'Status' or 'Manage', in the Storage System View, click the volume whose size you want to increase. The volume properties are now displayed on the left.2.Click 'Increase size'.3.Click 'Yes' to confirm. Caution: Once the data migration starts, the operation cannot be canceled.4.Once the migration has completed, restart your computer for changes to take effect. Then use Windows* Disk Management to increase the partition size on the volumes or add another partition.

This 'Increase size' link is not present. I'm confident that it was there in the past, as I expanded the original 500Mb volume to 700Mb after replacing the first two failed drives. Lastly, I also checked the boot-time utility, and this shows the drives but does have any option to expand the size of the array or volume.

Is there a reason that the Increase Size option is missing in the RST interface?

I recommend you get the latest version of the Intel Rapid Storage Technology from the link below:

https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22194&ProdId=2101&lang=eng&OSVersion... https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22194&ProdId=2101&lang=eng&OSVersion...

Try again the increase Size option, if is missing, or not working, then contact back with results.

I updated to the latest version, 11.7.0.1013, but still do not see the 'Increase Size' option for either the array or the volume:

If you try creating a new RAID, instead of increasing it. Do you see the remaining space available?

There is no option to create a new RAID volume on the set of disks; this is what my Status page looks like:

Isn't this where I should also see an option to create another volume on the free space in the array?

Could this be an access permissions problem of some sort? The user under which I'm logged in is part of the Administrators group, and I also tried to rt.-click 'Run as Administrator' on the Intel RST start menu shortcut, but the behavior did not change.

I see a

466 GB drive

a

466 GB drive

a

466 GB drive

a

233 GB drive

hmm....their is a 233 GB drive in your setup!

If you was hoping to do a matrix RAID setup unfortunately it is supported in a required way which is if you had four 466 GB drives you can setup one array for 699 GB RAID 5 across all four drives leaving you 233 GB on each to setup another array for 932 GB RAID 0.

But what you can't do as of yet that I know is setup matrix RAID on some of the drives that are in a array with free space you must do it across all the drives that are in a array with free space.

What I'm trying to do is simply expand the current RAID 5 volume to use the full amount of space available in the array; I do not want a separate partition or different RAID type. The RST software shows the total space on the array to be ~953Mb, as I'd expect, but nowhere can I find the option to expand the size of the current volume beyond the ~715Mb that was previously configured before replacing a failed drive with a larger disk.

You still have one 233 GB drive that needs to be replaced plus even if you do the ICH9R is not listed for support to do Capacity expansion.

I have similar problem

ICH10R RAID5 with 4x 2TB Disk I have switched one by one to 3TB disks, now I have 4x 3TB disks but no increase size button not in volume level nor in array...

Latest RST version 12.5.0.1066 installed

 

Any suggestions?

Thanks

Samvel, you have not performed a RAID array expansion so the capacity expansion option will not be shown. You have systematically changed the drives in the array, array expansion is adding one extra drive to an existing array. I suggest that you review the following articles related to this:
