doc/rados: Update mClock doc on steps to override OSD IOPS capacity config
Describe the steps involved to
- Specify a global value for osd_mclock_max_capacity_iops_{ssd,hdd}, and
- Override existing individually scoped values for OSDs determined during
start-up for osd_mclock_max_capacity_iops_{ssd,hdd}.
The above is to help with the following:
- Steps to override existing setting with a global value.
- reduce the number of entries in the mon store and instead use a single
global specification for all OSDs in the cluster in case the underlying
hardware is the same for all OSDs.

librbd: disallow "rbd trash mv" if image is in a group
Removing an image that is a member of a group has always been
disallowed. However, moving an image that is a member of a group to
trash is currently allowed and this is deceptive -- the only reason for
a user to move an image to trash should be the intent to remove it.
More importantly, group APIs operate in terms of image names -- there
are no corresponding variants that would operate in terms of image IDs.
For example, even though internally GroupImageSpec struct stores an
image ID, the public rbd_group_image_info_t struct insists on an image
name. When rbd_group_image_list() encounters a trashed member image
(i.e. one that doesn't have a name), it just fails with ENOENT and no
listing gets produced at all until the offending image is restored from
trash. Something like this can be very hard to debug for an average
user, so let's make rbd_trash_move() fail with EMLINK the same way as
rbd_remove() does in this scenario.
The one case where moving a member image to trash makes sense is live
migration where the source image gets trashed to be almost immediately
replaced by the destination image as part of preparing migration.
EMLINK is returned by rbd_remove() if the image is a member of a group.
Add a dedicated exception similar to ImageBusy or ImageHasSnapshots and
a test for it.

As the result, unlink() finishes properly, but truncate() is not aware
of it and does:

2) releases same allocations again

test/librbd/test_notify.py: conditionally ignore some errors
In 2020, commit 01ff1530544c ("librbd: make all maintenance op
notifications async") introduced a backwards compatibility issue where
if exclusive lock is held by an older (octopus and below) client and
a maintenance op is proxied to it from a newer client, the newer client
interprets the notification for the in-place completion of the op as
the notification for the acceptance of an async request and expects
another notification for the completion of the op which never comes.
In 2021, this bug was discovered and test_notify.py was amended to
ignore it in commit 9c0b239d70cd ("qa/upgrade: conditionally disable
update_features tests").
However the two update_features tests that started hanging and got
disabled weren't the only ones to misbehave. Rename, create_snap and
remove_snap tests were affected too but didn't hang or fail because
librbd also filtered certain errors codes like EEXIST and EINVAL.
Taking rename is an example:
1. a rename request is sent to from a newer client (N) to an octopus
client (O)
2. O successfully renames the image and sends a completion notification
with result = 0
3. N mistakes it for async request acceptance
4. after a timeout, N resends the rename request to O
5. O sees that an image already has that name (after step 2) and sends
a completion notification with result = EEXIST
6. N interprets it as async request denial and bubbles up EEXIST,
however right before returning control from Operations::rename()
EEXIST is filtered and 0 is returned to the user
So back then rename, create_snap and remove_snap tests continued to
pass but started taking 30+ seconds instead of completing immediately.
In 2025 we did away with filtering error codes in commit 66508cdaa190
("librbd: stop filtering async request error codes") and these tests
started to fail. Following the approach taken in commit 9c0b239d70cd
("qa/upgrade: conditionally disable update_features tests"), let's
ignore these failures based on the same environment variable.
