If you run "partprobe" after you resize in your second example, is the change visible in "parted"? On Wed, Apr 11, 2018 at 11:01 PM, Alex Gorbachev wrote: > On Wed, Apr 11, 2018 at 2:13 PM, Jason Dillaman wrote: >> I've tested the patch on both

Re: [ceph-users] rbd-nbd not resizing even after kernel tweaks

I've tested the patch on both 4.14.0 and 4.16.0 and it appears to function correctly for me. parted can see the newly added free-space after resizing the RBD image and our stress tests once again pass successfully. Do you have any additional details on the issues you are seeing? On Wed, Apr 11,

Re: [ceph-users] rbd-nbd not resizing even after kernel tweaks

I'll give it a try locally and see if I can figure it out. Note that this commit [1] also dropped the call to "bd_set_size" within "nbd_size_update", which seems suspicious to me at initial glance. [1]

Do you have a preliminary patch that we can test against? On Wed, Apr 11, 2018 at 10:27 AM, Alex Gorbachev wrote: > On Wed, Apr 11, 2018 at 2:43 AM, Mykola Golub wrote: >> On Tue, Apr 10, 2018 at 11:14:58PM -0400, Alex Gorbachev wrote: >> >>>

[ceph-users] rbd-nbd not resizing even after kernel tweaks

I am running into the problem described in https://lkml.org/lkml/2018/2/19/565 and https://tracker.ceph.com/issues/23137 I went ahead and built a custom kernel reverting the change https://github.com/torvalds/linux/commit/639812a1ed9bf49ae2c026086fbf975339cd1eef After that a resize shows in
