DSM 7.2.1-69057 Update 5 on Proxmox 8.2.2 - storage pool has degraded

[nexuscan]

Hello,

 

I have bare metal desktop PC and DSM 7.2.1-69057 Update 5 running on Proxmox 8.2.2.

 

I have six disks which I used like that:

 

On Proxmox:

I add 512GB ssd disk (not important for this issue).

I add every disk separately and I create RAW data file inside each disk 998 GB (for RAID 10), so I can able use that file to add disk in synology.

I add 2TB disk for full raw back up of RAID 10 system.

 

on Synology

one 512GB ssd disk SHR (single disk mode) for system itself only use.

four 1TB disk RAID 10 for my all data are in here

one 2TB disk SHR (single disk mode) for my all data backup is here from RAID 10. using as a hard copy of everything.

 

Synology system gives error that on second disk "storage pool has degraded" on RAID 10.

 

so how can I resolve that issue ?

Can I try to remove this problematic disk in RAID 10 system. and re-format in proxmox and re-create that RAW disk file. and then I can try to add this new disk file in RAID 10 system ?

 

I want to test this disk before buying new disk. so therefore I can follow that above steps to check disk is working normal. and to be sure it just something happened to disk file in proxmox.

 

Please check attached screenshots files.

 

Thank you.

Disconnect disks with critical issues first through Tasks -> Disable Drive in Disk Manager.
Through this process, the problematic disk is removed.

You can proceed as mentioned for disk replacement.
In Disk Manager, select Repair and proceed.

If a message appears indicating that a new disk needs to be initialized, you may need to initialize it first.
