Then you either made a mistake or ran into a bug. Both "normal" disk partitions and logical volumes are regular block devices and tune2fs or other tool operating on block devices will see no difference between them and treat them identical. On 30.04.2016 12:42, Rob Townley wrote: > Not in my testi

tune2fs against a LVM (albeit formatted with ext4) is not the same as tune2fs against ext4. Could this possibly be a machine where uptime has outlived its usefulness? On Thu, Apr 21, 2016 at 10:02 PM, Chris Murphy wrote: > On Tue, Apr 19, 2016 at 10:51 AM, Matt Garman > wrote: > > > ># rpm -qf
