The "XFS (md1): EXPERIMENTAL online shrink feature in use. Use at your own risk!" alert is appearing in my syslog/on my console. It started after I upgraded a couple of drives to Toshiba MG09ACA18TE 18Tb drives. Strangely the alert appears for one drive and not the other. There was no configuring or setting anything up wrt the disks, just installed them straight out of the box. Is there a real risk? If so, is there a way to disable the feature?
