Question How to increase capacity on Windows 2019 Raid1 array

[Mollcons]

I have a Windows Server 2019 system with 5 drives, 1 is the system drive C, the remaining 4 ports comprise 2 Raid1 arrays each of 500Gb. One of the arrays is working fine, but yesterday the first one stopped being accessible. When I examined the Storage Pool description, I saw that one of the Seagate drives is showing as SATA and the other one is only showing as ATA and is showing in the Chassis description as "PCI Slot 0: Adaptor 0" whereas the other drive is showing "Integrated: Adaptor 2".

I do have a pair of WD Black 2Tb drives which are spare. How do I convert the Seagate 500Gb raid array to the WD 2Tb array, without losing any data on the one Seagate drive?

Simplest way is to restore from backups. You do have backups, don't you ? If you can't afford to lose the data, then you must have backups.

You could install one of the 2TB drives, resilver the array. Remove the 500GB drive. Fit the second 2TB drive and resilver the array a second time. If it succeeds, you now have a backup.

1. What is the requirement of this RAID array?

2. You DO have a known good backup of everything, right?

Having copied one of the 500Gb drives onto one of the 2Tb drives, I then attempted to reinstall both new 2Tb drives but found that the Storage Pool would not reappear. Subsequently, I ascertained that the second 2Tb drive is somehow defective.

I have now ascertained that both the original 500Gb drives can still be accessed from my Windows11 laptop using a disk caddy I have and both contain all the data. But when I reinstalled these to the server, the Storage Pool shows one of the disks as being ATA connected to PCI Slot 0: Adaptor 0: Channel 0: Device 0 whereas the other drive is Integrated: Adaptor 2: Port 2.

I am puzzled. I may have to purchase a new pair of disks (at least 1Tb storage, I think) and retry installation.

I have repaired the virtual disk concerned, but one of the two disks is still showing as ATA rather than SATA and is still showing as connected to Adaptor 0 and Channel 0.

What do I do to correct this issue?

 

[Mollcons]

I have now purchased two new drives (both 2Tb) and successfully installed them and copied the data from the original 500Gb drive(s) to the new Virtual Disk.

Interestingly, the new Virtual Disk shows one drive as SATA and the second as ATA.
