ERROR: job failed with err -61 - No data available - How to fix

[sreenath]

Hi Team,

I have one NVMe Drive where all the VM disks are saved. I observed the SMART test showed FAILED for NVMe and i started to experience VM Crashing. So to replace the drive, i thought i will backup the VM. but i am unable to back it. i get the below Error.

ERROR: job failed with err -61 - No data available
INFO: aborting backup job
INFO: resuming VM again
ERROR: Backup of VM 100 failed - job failed with err -61 - No data available
INFO: Failed at 2025-04-28 16:09:43
INFO: Backup job finished with errors
TASK ERROR: job errors

I can confirm that backup for other VM's work fine. except this one. and unfortunately, this VM is the most important one i have.

Any recommendation on how to get around to replacing my drive and saving my VM ?

Since failure, i have added a second NVMe drive which is empty (potential replacement candicate).

Please help.

Hi,
you could use tools like ddrescue or qemu-img convert --salvage ... (see the manpage for more details) to salvage/copy the parts of the VM image that can still be read. Use pvesm path STORAGE:VOLUME to get the path on the host for the virtual disk.

I also encountered ERROR: job failed with err -61 - No data available. During the backup process, I used dmesg -w to find the hard disk error. Replace the disk
