[pve-devel] qemu_drive_mirror

[Alexandre DERUMIER]

Seem that the block-job die.
Last time I have see that, it was because of a sector error on the volume.
Do you have tried with another volume ?
(does the backup work?)

We should be able to see what exactly happen it with qmp events, but last time I have tried, I can't get them ....

Maybe does it work since this commit ??:

I have use drive-mirror in production on around 200 volumes without error, the only one dying was a sector error on drive.
