Hi all, I am running Kubernetes on CoreOS and use rbd binary exctracted from ceph/ceph-docker/config image to map images to CoreOS host. Everything works just fine except when trying to unmap the volume. It doesn’t unmap and gives following error: $ rbd showmapped id pool image snap device 0 rbd dcops-db - /dev/rbd0 $ sudo rbd unmap /dev/rbd0 rbd: '/dev/rbd0' is not an rbd device rbd: unmap failed: (22) Invalid argument When I was running strace against rbd unmap command I found out that it fails while trying to get stat of this file: lstat("/sys/devices/rbd/0/0", 0x7ffdfdc13f10) = -1 ENOENT (No such file or directory) On other machine running ArchLinux instead of looking for either /sys/devices/rbd/0/0 or /sys/devices/rbd/0/254 (which are values of minor and major), rbd unmap looks for /sys/devices/rbd/0/minor and reads value from there. And rbd unmap
works as supposed. CoreOS runs kernel 4.0.5 #2 SMP Fri Jul 10 06:25:01 UTC 2015 x86_64 Intel(R) Xeon(R) CPU E5620 @ 2.40GHz GenuineIntel GNU/Linux ArchLinux where rbd works runs kernel 4.1.3-1-ARCH #1 SMP PREEMPT Wed Jul 22 20:37:12 CEST 2015 x86_64 GNU/Linux rbd version on both machines is the same $ rbd --version ceph version 0.94.2 (5fb85614ca8f354284c713a2f9c610860720bbf3) What can I try to fix the unmap issue. Thank you! - Anton |
