Hi, I'm getting this error every time I want to move a disk of the VM to another disk. I state that I have all NAS (physical, Synology) in NFS

TASK ERROR: storage migration failed: target storage is known to cause issues with aio=io_uring (used by current drive)

can someone help me? Sorry for the English but I'm translating with Google
 
Change the disk to not use Async IO =io_uring (in the advanced section)
 
Select it in the GUi and click edit
 
Hi all,

This kind of error is annoying...

A default option generating errors is not an acceptable option, at least for us.

Can we hope someone will solve the problem?

If not, I will change on our clusters from io_uring to native.
Don't know performance gain / loss but with our workloads, lose some % is acceptable, an error : not really.

Thank you,

Christophe.
 
There is no shoe that fits all, so unless you change from NFS to something better, you need to change the I/O setting.
Yes, it is my understanding.

In my case it's a move disk from a Ceph storage to an iSCSI one.

Best solution for me : chose an async_io : threads, which seems to live together with any cache policy and any storage type.

Regards,

Christophe.
