And it appears to behave well. (A few hours compile/clean cycling kernel builds on that filesystem were OK).
Historically I've done: sync echo platform > /sys/power/disk echo disk > /sys/power/state # resume
and had filesystem corruption (only on this machine, my other hibernating xfs machines don't have this problem)
So doing: xfs_freeze -f /scratch sync echo platform > /sys/power/disk echo disk > /sys/power/state # resume xfs_freeze -u /scratch
Works (for now - more usage testing tonight)
