Ive had Proxmox running for many years, and it works great. Today I've received 10 emails from my server with the following message:

Code:
This is an automatically generated mail message from mdadm
running on proxmox

A Fail event had been detected on md device /dev/md126.

It could be related to component device /dev/sda1.

Faithfully yours, etc.

P.S. The /proc/mdstat file currently contains the following:

Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md123 : active (auto-read-only) raid1 sdc1[0] sdu1[1] sdv1[2]

      2094080 blocks super 1.2 [3/3] [UUU]
      
unused devices: <none>

Each message is similar and lists a different device. I'm not sure what this means or what to do about it?

My system has two satadom's in ZFS mirror config for the main proxmox rootfs, and then a lsi controller card passed to Truenas with 24x drives for main storage... so I don't use software raid (AFAIK) if this is what this is referring to? ?

I guess I'm not sure what the issue is or what to do about it.

Thanks in advance for your help.

I'm seeing the same issue on some M.2 PCIe NVMe drives at boot on PVE 8.0.4 with the Linux 6.2.16-8 kernel. They are passed through to a TrueNAS VM. Before the VM starts and it grabs the PCIe drives, PVE e-mails this error. No errors show up in TrueNAS.
 
Did either of you figure anything out with this? I am now also starting to see these messages.
