[pve-devel] [PATCH manager 0/2] fix #5570 ceph mds: allow custom MDS IDs from the UI

[pve-devel] [PATCH manager 0/2] fix #5570 ceph mds: allow custom MDS IDs from the UI

[Aaron Lauterer]

The ID for the MDS cannot start with a number [0]. The first patch adds
a check for this.

The second patch is the actual fix, by reworking the edit window when
adding new MDS'.

By allowing the users to set the name of the MDS directly, we can catch
the situation where the hostname starts with a number and let the user
decide how it should be named. Similar to what they can already do on
the CLI.


Another approach would be to leave the UI as is and catch the situation
in the backend. If an ID that starts with a number is detected, we could
prepend it with a default string.

[pve-devel] [PATCH manager 2/2] fix#5570 ui: ceph: make MDS ID configurable

[Aaron Lauterer]

Since the ID of an MDS cannot start with a number [0], we cannot just
use the hostname in all situations, as they are allowed to start with a
number.

By having an extra field for the MDS ID, we can check for that via a
regex. This field is filled with the hostname when the host on which it
should be installed is selected.

This means, we can remove the extra ID field, as additional MDS, and
their unique ID can be set with the new ID field.

Is there a check in the backend whether the name ends with a hyphen? If
not, should there be one?

Also, while at it, maybe also set `maxLength` to a sensible value?
E.g. while the API schema allows up to 200 characters, it then fails to
create a task log file with "File name too long" :^)
~ 180 characters seem to be fine, but probably something like 128
characters is already a pretty sensible limit.

Yes, the parameter checks [0] against the Ceph Service Regex [1] which 
is basically a hostname regex.

nice catch. we might want to lower the limit in the API then, and could 
also set the limit in the GUI.
There might be other places in the API with a similar issue... glancing 
at all the other Ceph Services which can get customized names with the 
API/CLI.

Perfect, that's fine then.

With that resolved, you can also consider the entire series:

I really was just mashing the keyboard in the usual "lets see what
breaks" fashion here :^)

Can be done in a separate patch(-series) though, as I don't think its
*that* important - esp. considering such long names are (hopefully) very
much an edge case.

Re: [pve-devel] [PATCH manager 0/2] fix #5570 ceph mds: allow custom MDS IDs from the UI

[Christoph Heiss]

Tested this on a small 3-node cluster, works as advertised. Code looks
good too, just one small comment on the second patch.

But otherwise please consider the series at least:

applied with a small s/service_id/serviceID/ style fix squashed into the
UI patch plus added the missing space in the subject between "fix" and the
issue ID, thanks!

Oh, I also made a follow-up [0] that makes the field required now to avoid
an API error if the user clears the field before submitting.<
