Hello. I have raid 10 of 4 1.2 TB disks. I want to replace them with 2.4 TB drives. Question: Does this storage system support hot disk replacement? How can I see if the replacement was successful? How can you then increase your storage space?

Hi,
Please don't expect immediate forum responses or responses during the weekend.
Question: Does this storage system support hot disk replacement?
Answer: Yes
How can I see if the replacement was successful?
Check in WebPAM
I assume you want to rebuild to the 2.4TB drives. So you would have to replace 1 drive at a time and let the rebuild complete before replacing another drive. The disks will need to be unconfigured. Replacing the drives won't increate LUN size.
How can you then increase your storage space?
To increase LUN size you'd use the migrate option. In WebPAM that's in System > Administration > Background Activities. Be advised that one started a migration cannot be stopped, canceled or paused and can take a long time to run.
Also, if this is an iSCSI LUN, making the OS of the host recognize the increased size of the LUN is dependant on what you are running. It's simple with Windows, difficult with macOS and I'm not sure about VMware or Linux.

Hi. Thanks for the answer. Can you clarify: 1. When replacing disks, do I need to copy the data that is there or not. Will the VMs work when replacing disks? 2. After replacing disks, the space will not increase automatically. Do I need to transfer all the data to another array and then expand this array to the size of the disks? Sorry for such details: I have VMs running on them, so I need to replace and expand the disks without any problems.

Also, tell me, I can’t find my messages that I wrote in 2024. Are they deleted according to the regulations?

Hi,
1. When replacing disks, do I need to copy the data that is there or not.
That's what the rebuild accomplishes. There are no files on any single disk, they are written across all the disks in the RAID set.
Will the VMs work when replacing disks?
As long as you do things correctly and don't take the storage offline, the host won't see any changes to the storage.
2. After replacing disks, the space will not increase automatically.
If you rebuild all the disks with larger disks, the storage won't change in any way. It will be the exact same size.
Do I need to transfer all the data to another array and then expand this array to the size of the disks?
This is the easiest thing to do if you have other storage available. Move all VMs to the other storage then delete the existing array and recreate a new array and LUN. Then move the VMs back.
As mentioned previously, I don't know how to expand a VMfs filesystem or if it's even possible. You can migrate the LUN to use all the available disk space, but I don't know if it's possible for VMware to use the additional space in this situation.
Also, something happened awhile back and we lost the forum. It was restored but some of the latest posts were lost.

To sum it up: I'm currently hot swapping disk after disk in my RAID 10?

Then I do a migration to increase the size of the array?
