ata2 kernel message in KVM VM

[frantek]

One of many Debian 9 KVM VMs logs once a day:

Mar 13 22:34:37 - kernel ata2: hard resetting link
Mar 13 22:34:37 - kernel ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

Mar 13 22:34:37 - kernel buffer_io_error: 246 callbacks suppressed

This VM resides on a standalone node with the latest PVE version and with plain QCOW2 files as storage. No LVM, no ZFS.

Do I have to worry about this? How to fix this?

Hmm, maybe you should check if your filesystem is still ok. Also if sata is causing troubles you could switch to scsi to attach your disks.

My fault ... the messages are sent by rsyslog from an other device. My Linux VMs user virtio and XFS and not SATA and EXT4 ...

In that case I suggest you check the sata cables on your other device. This messages can arise from bad cables/connections. Also I would check the filesystem there and backup the data if important.
