I have used compress=lzo for years, kernels 3.8, 3.13 and 3.14 (a bunch of
machines), without a single glitch; heavy snapshotting, single dev only, no
quota.  Until recently I did never balanced.

I did have a case of ENOSPC with <80% full on 4.7 which might or might not
be related to compress=lzo.
