Ceph » rbd

Looks like referenced in https://www.spinics.net/lists/ceph-devel/msg40171.html

This is happening in public release 12.2.3

Thanks, got it - seems that resolution stalled on the kernel side. I will follow up there.

I went ahead and built a custom kernel reverting the change https://github.com/torvalds/linux/commit/639812a1ed9bf49ae2c026086fbf975339cd1eef

After that a resize shows in lsblk and /sys/block/nbdX/size, but not in parted for a mounted filesystem. Unmounting flesystem still does not change the size.

Unmapping and remapping the NBD device shows the correct size in parted.

this is resolved by the latest patches in nbd.c

I made this issue in Ubuntu to get the fix in Ubuntu kernels:
