Hi,
=> How about adding question about running on bare metal vs. virtualized ?
=> How about asking for layout options, like single, stretched, how many
DCs stretched over ?
=> perhaps, too, how many OSDs in the biggest cluster ?
H/W section:
in "Which type of storage devices are used?"
=> could add Optane
=> and could add specific question for NVMe and Optane for the
use case (e.g., RocksDB/WAL, OSD, OSD for object index)
in "Which OSD layout features do you use?"
=> s/Seperate/Separate/ journal device (FileStore)
=> could add separation of "RocksDB and WAL and data"
RGW section:
=> How about asking
- for the number of RGW ?
- for largest objects stored ?
- how many objects in buckets, how many buckets ?
- how many realms, max # zonegroups per realm, max # of zones
per zonegroup ?
- how about asking RGW multi-site more detailed ? (as max
values, how many sites, how many zonegroups, how many zones per group)
(we ask more detailed in MDS section, too)
CephFS section:
in "Number of files (getfattr -d -m ceph.dir.rfiles /mnt/cephfs)
(for largest cluster, if multiple clusters)": the last should be
something 10G+ or better use for M and G the more common 'm' and 'bn'
for numbers.
Don't we wanna ask for some wish list features/functionality with prio ?
(So, may be 2-3 items max.)
G,

Sage just shared the link to the survey on Zoho. Thanks!
Minor feedback (sorry about that, some things only become clear seeing
the actual forms) that'd be nice to address but are optional:
Page 1:
- "Is telemetry enabled in your cluster*s*" (might have more than one)
And then also add "Partially" as an answer.
- Can we had the "If not" sections unless folks have not picked "Yes"?
- "How do you participate in the Ceph community?"
- Add "Member of Ceph Foundation" as an answer ;-)
- The country list is intimidating; is there any way with Zoho to make
this a drop down selection or tag cloud? (This is purely visual)
Page 2:
- Total usable capacity should also be a number entry to match the
previous questions
- Is someone possibly running "Master" or do we rather not even dare
ask?
- "Which Ceph Manager modules" probably should have a "I do not know"
answer, or "Not applicable" (if < Luminous), and definitely also
"Telemetry" / "Prometheus"
- Messenger type (TCP-Posix) deserves being the default, or adding a
(Default) note in case users are confused
Page 3:
- IHV -> add "Prefer not to say"
Page 4:
- "What are the use cases" -> add "Backup"
Page RBD:
- "Do you use snapshots" -> No already opens a text entry field, the
last "Why?" is perhaps redundant on that page?
Page RGW:
- That the workload choices differ across all pages is highly annoying
and will make data analysis harder ;-)
Page CephFS:
- See previous comment
- Everywhere else the environment status is before the workload question
- My comments regarding "Number of files" being unclear about which way
to round have not been addressed. I'd suggest to add a "< " in front
of the fields instead of a "~" to turn them into ranges.
Thanks!,
Lars
