io-qcow2 failures on zfs

io-qcow2 failures on zfs

[Richard Henderson]

I'm doing some testing on one of the Linaro build machines and I reliably see

Summary of Failures:

712/790 qemu:block / io-qcow2-150                                                 ERROR 
        5.24s   exit status 1
777/790 qemu:block / io-qcow2-copy-before-write                                   ERROR 
       16.31s   exit status 1
779/790 qemu:block / io-qcow2-244                                                 ERROR 
       37.10s   exit status 1

This is x86_64 ubuntu 22.04, same as my laptop, so the only thing I can think is the 
filesystem type:

hackpool-0/home/richard.henderson /home/richard.henderson zfs 
rw,nosuid,nodev,noatime,xattr,noacl 0 0

Any thoughts?

What output do you get when running the tests directly? i.e.:

cd tests/qemu-iotests/
./check -qcow2 150
./check -qcow2 copy-before-write
./check -qcow2 244
