So nothing to sync.
But it takes some time to invalidate and shrink 20 million dentries
and inodes and 13 million buffer heads and associated caches.
Also, cpu bound now makes more

Is sync broken for drbd?
PS: Writing to a (much smaller) local partition instead of a drbd
partition sync takes several seconds, and the following umount takes
just a few millisecs, as expected.

Hi folks,
using drbd umounting /data1 takes >50 seconds, even though the file
system (ext4, noatime, default) wasn't accessed for more than 2h.
umount ran with 100% CPU load.
# sync
# time umount /data1
real0m52.772s
user0m0.000s
sys 0m52.740s
This appears to be a pretty long
