RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
As the subject, and the bug is from the discussion of https://bugzilla.redhat.com/show_bug.cgi?id=1873925#c10 .


Version-Release number of selected component (if applicable):
qemu-kvm-7.0.0-3.el9
librbd1-16.2.4-5.el9.x86_64


How reproducible:
100%

Steps to Reproduce:
# qemu-img create 'rbd:rbd/aa/new3:conf=/etc/ceph/ceph.conf:id=admin:key=AQBwUmlfB9VwKhAA0HwqNhKCfarcItKtCR9ulg==' 1M
Formatting 'rbd:rbd/aa/new3:conf=/etc/ceph/ceph.conf:id=admin:key=AQBwUmlfB9VwKhAA0HwqNhKCfarcItKtCR9ulg==', fmt=raw size=1048576
qemu-img: rbd:rbd/aa/new3:conf=/etc/ceph/ceph.conf:id=admin:key=AQBwUmlfB9VwKhAA0HwqNhKCfarcItKtCR9ulg==: error rbd create: No such file or directory

# qemu-img create rbd:rbd/aa/testtt.img 1G
Formatting 'rbd:rbd/aa/testtt.img', fmt=raw size=1073741824
qemu-img: rbd:rbd/aa/testtt.img: error rbd create: No such file or directory


Actual results:
As above, created failed with ' No such file or directory'.


Expected results:
A more clear error hint info like "No a namespace named 'aa'"N=.

v1 posted: https://lore.kernel.org/qemu-devel/20220516100324.61122-1-sgarzare@redhat.com/T/#u

The new output will be:
  $ qemu-img create rbd:rbd/namespace/image 1M
  Formatting 'rbd:rbd/namespace/image', fmt=raw size=1048576
  qemu-img: rbd:rbd/namespace/image: namespace 'namespace' does not exist

commit 66dc5f9606bec7ce029e98a90f209153dfade82e
Author: Stefano Garzarella <sgarzare>
Date:   Tue May 17 09:10:12 2022 +0200

    block/rbd: report a better error when namespace does not exist
    
    If the namespace does not exist, rbd_create() fails with -ENOENT and
    QEMU reports a generic "error rbd create: No such file or directory":
    
        $ qemu-img create rbd:rbd/namespace/image 1M
        Formatting 'rbd:rbd/namespace/image', fmt=raw size=1048576
        qemu-img: rbd:rbd/namespace/image: error rbd create: No such file or directory
    
    Unfortunately rados_ioctx_set_namespace() does not fail if the namespace
    does not exist, so let's use rbd_namespace_exists() in qemu_rbd_connect()
    to check if the namespace exists, reporting a more understandable error:
    
        $ qemu-img create rbd:rbd/namespace/image 1M
        Formatting 'rbd:rbd/namespace/image', fmt=raw size=1048576
        qemu-img: rbd:rbd/namespace/image: namespace 'namespace' does not exist

QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass.
Comment 10 Tingting Mao 2022-09-08 03:24:55 UTC 
Tried with the latest qemu, the hint info is as expected. Thanks.


Tested with:
qemu-kvm-7.1.0-1.el9
kernel-5.14.0-160.el9.x86_64


Steps:
# qemu-img create 'rbd:rbd/aa/new3:conf=/etc/ceph/ceph.conf:id=admin:key=AQBwUmlfB9VwKhAA0HwqNhKCfarcItKtCR9ulg==' 1M
Formatting 'rbd:rbd/aa/new3:conf=/etc/ceph/ceph.conf:id=admin:key=AQBwUmlfB9VwKhAA0HwqNhKCfarcItKtCR9ulg==', fmt=raw size=1048576
qemu-img: rbd:rbd/aa/new3:conf=/etc/ceph/ceph.conf:id=admin:key=AQBwUmlfB9VwKhAA0HwqNhKCfarcItKtCR9ulg==: namespace 'aa' does not exist

# qemu-img info rbd:rbd/aa/testtt.img
qemu-img: Could not open 'rbd:rbd/aa/testtt.img': namespace 'aa' does not exist
