Hi again, apologies for my tardiness. I've switched to Ubuntu server rather than Debian and all appears to be well again. I can only assume that it is an environment/dependency issue in Debian.

Hi,

i have the same Problem - im using Ubuntu 20.04 with logic volumes (LVM). If I restore a file it only shows the red triangle. Is there any solution?

Are you testing on latest XO virtual Appliance with XO also up to date?

@olivierlambert

xo-server 5.86.3 and xo-web 5.91.2
I also have tested it with the latest XOA.

Are you using multiple disks under the same VG or LV?
