Hi.
Since this morning I can´t start a VM. I get this error:

kvm: -drive file=/mnt/pve/BACKUP_DADOS/images/103/vm-103-disk-0.raw,if=none,id=drive-sata0,discard=on,format=raw,cache=none,aio=io_uring,detect-zeroes=unmap: Could not open '/mnt/pve/BACKUP_DADOS/images/103/vm-103-disk-0.raw': Input/output error
TASK ERROR: start failed: QEMU exited with code 1

Hi @mikegodin23 , welcome to the forum.

Could not open '/mnt/pve/BACKUP_DADOS/images/103/vm-103-disk-0.raw': Input/output error

The message does mean that there was an IO error trying to open the file. The error likely comes from the Kernel and can be caused by a few things:
- actual disk read error
- slow enough disk that the IO gives up
- bad disk interface (usb/etc)
- less likely - io_uring complication

You can try a few things:
- read the whole file: dd if=[filepath/name] of=/dev/null
- move the file to another location, change the config and try to start
- check the hardware stats of the disk
- check the "dmesg"

Good luck

Hi @bbgeek17 and forum. Good night.
I was getting more and more errors... and decided to "build " another V, for the same purpose, with a different structure and using other directories/ZFS (local-lvm for system and ZFS for data. I powered off the previews VM until I get everything settle on the new one.
Later I would like to "free" the directory that was having trouble (BACKUP_DADOS), try to remove it and use the disk space.
Can anyone help me to know/verify if is safe to remove it or see what is using it, before removal?
Thanks
Miguel
