No Spare pool after adding extra disks

Sjpillai — Wed, 04 Jun 2025 09:49:36 GMT

Hi All,

We have a FAS2650 2 node cluster with 12 disks each of 1.63TB.We have added another 5 disks to increase the aggregate space using the storage aggregate add-disks -aggregate sas_data_1 -raidgroup all -diskcount 5 command. The issue is that it is not showing any disk in spare pool. But each node has disks as Root-Data Partitioned Spares.

storage aggregate show-spare-disks

Please advise

1)If this setup can survive a disk failure.

2) why is disk 1.0.12 showing as owned by both nodes

3) what can be done to get 1 disk into spare pool

Can you post the output from "disk show -partition-ownership" ?

Thanks for posting, additional ask please. can you report what you have in your original post, but in the txt format? but run row 0 first.

row 0 storage aggregate show-spare-disks

With ADP spare disks, you can have a spare data partition and a used root partition (or vice versa) on the same disk.

Hello,

Can you check your max raid siez befor add ?

storage aggregate show -fields maxraidsize

To be sure, you dont create another RG

And this command to have an old vision, but some time better 🙂

system node run -node * -command "sysconfig -r"
