Hello

I have install a proxmox server to replace an esxi server.
=> I am new to proxmox ;-) and it is much beter than esxi !!!

On this server I have some VM Ubuntu, a pfsense VM and an OMV VM with 2 disk for the data in raid (mirror).
But I get often error and the raid is KO.

Code:
cat /proc/mdstat
Personalities : [raid1] [raid0] [raid6] [raid5] [raid4] [raid10]md0 : active raid1 sda[1] sdc[0](F)      3906886464 blocks super 1.2 [2/1] [_U]      bitmap: 26/30 pages [104KB], 65536KB chunkunused devices: <none>

It can be sda or sdc that has the error.
On OMV the SMART state of the 2 disk are Ok

sudo smartctl -t long /dev/sdc => give no error

I have try to use the driver :
virtio-scsi-single -> error after some days
virtio-scsi-pci -> error after some days
lsi -> main disk (not the raid one) does not boot

The 2 disk are Ironwolf ans buy less than a year. Never had problem on esxi

Any idea how to solve?
Thanks
