I may have to cancel the defrag before it is completed though, at the current rate it will take around a month to complete.!!! EDIT !!! I didn't see your defrag posting till after posting the below. (Had this thread opened, then switched to analog life, and neglected to refresh upon return. ) Will be interesting to see the effect.
Here are some of the output from e4defrag to show how much the extents are tweaked as part of the defrag. I have no point of reference what number of extents are normal/acceptable for 20-80GB files.

The system is on 24/7 with a reboot once every 1-4 weeks to apply security updates so the issues is mainly an annoyance as long as it isn't a sign of horrible things to come.That is actually very good to hear.
I don't want to be pessimistic, but there's an ~even chance that the 8==>10 won't change anything (except capacity). In either case, just so you don't feel pressured into doing the -grow asap, it might be useful to devise a "coping plan" so that this wart has minimal impact on life-and-wife. E.g., you can minimize the frequency of shutdown/boot-up by seeing what procedures for Hibernate are available in Ubuntu.
And, we can force the stall-event to happen at the last stage of boot-up, and avoid the surprise annoyance, as currently. This might also avoid the rattling of those 5 disks, but that is just a "theory" I have. The 120 seconds of timeout is probably unavoidable. Details on this forcing can wait till later--just something to ponder in the meantime.
Next time you reboot (normally--no need to force the event), try to cause the stall with the following command:
Code:dd if=/dev/zero of=/mnt/storage/40MBz bs=8M count=5 oflag=direct
If the system can be forced to stall as part of the boot-up that would be a good last resort if the other options fail. I will give that command a try after next reboot whenever that is.
