Confused with errror about disk failure

Hi, I am running proxmox on 2 machines for 1 year now, and everything seem to work fine, most of the times. Today, I was messing arround on one of them and came across the following error message in dmesg and journactl:

Code:
Jul 27 20:56:14 atlas kernel: md/raid1:md127: Disk failure on sdd1, disabling device.
Jul 27 20:56:14 atlas kernel: sd 8:0:0:0: [sdd] Synchronizing SCSI cache
Jul 27 20:56:14 atlas kernel: ata9.00: Entering standby power mode
Jul 27 20:56:14 atlas kernel: sd 9:0:0:0: [sde] Synchronizing SCSI cache
Jul 27 20:56:14 atlas kernel: ata10.00: Entering standby power mode
Jul 27 20:56:15 atlas kernel: md127: detected capacity change from 4190080 to 0
Jul 27 20:56:15 atlas kernel: md: md127 stopped.
Jul 27 20:56:15 atlas kernel: sd 13:0:0:0: [sdf] Synchronizing SCSI cache
Jul 27 20:56:15 atlas kernel: ata14.00: Entering standby power mode
Jul 27 20:56:15 atlas mdadm[1086]: mdadm: No array with redundancy detected, stopping

Problem is that this message does not make sense at all!

My setup is as follows:

sata ssd 1 --> sda
sata ssd 2 --> sdb

These make a raid1 zfs pool that I use for as boot drive and for lxc/vm storage.

In addition I have another sata ssd, that provides adittional lvm storage to proxmox. This is sdc.

Now, I also have another 3 sata hdd drives that are attached to a sata controller (m.2 type, asm 1066 chip). These drives are identified as sdd, sde, sdf.
The sata controller is passed through to a truenas virtual machine, which takes control of the drives. In truenas these drives form a raidZ1 pool which works fine all the time.

So, what is this error about? What sdd1 disk failure and what raid1 array?

Code:
root@atlas:~# cat /proc/mdstat
Personalities : [raid1]
unused devices: <none>


The last two commands do not return anything, I had run them myself. There is no md* device or sdd device in my setup.
Like I said discs sdd sde and sdf are passed through to truenas vm.
