btrfs user survey?

btrfs user survey?

[Francis Galiegue]

Hello list,

At this point in time, btrfs has gained a lot of interest, and not
only a passing one. So, it is, imho, the ideal time to build up a
survey to monitor how btrfs is used today (or _was_ used - I have
knowledge of people that started to use it but dropped for various
reasons).

Of course, I'm only one user among many, but here is a sample of
questions for this survey in case anyone is interested:

* Do you use btrfs currently?
[ ] yes, but not as a root filesystem
[ ] yes, as a root filesystem
[ ] no

* If not, what prevents you from using them?
[ ] lack of a full blown fsck
[ ] horror stories from other users
[ ] lack of support from my favorite distribution
[ ] other

* If yes, how long have you used it?
[ put answers here related to milestones in btrfs design - I don't know=
 them ]

* Do you use the following features of btrfs:
[ ] defragment
[ ] online shrink
[ ] online expand
[ ] snapshots
[ ] RAID
[ ] [others - I only mention the ones I know]

* How many btrfs filesystems do you currently have?
[ ] 1 only
[ ] 2-5
[ ] More than 5

* How many btrfs filesystems have failed upon you?
[ ] None!
[ ] [etc etc]

Well, all in all, you get the idea, and I'm probably not the guy to
craft questions for such a survey. But having input from as large a
panel of users as possible would be a nice thing to have.

Comments?

Your questions are fine -- I might add:

* Rank the following future features in importance, 4 == most important
[ ] working fsck
[ ] GUIs for userspace actions e.g. snapshots
[ ] data deduplication
[ ] hot data relocation

Please use something like Google Spreadsheets (which has a forms
option) if you're going to run such a survey, rather than having
everyone reply on-list -- we shouldn't bother this list with any
results other than the final summary.

You're missing RAID levels above 1, and deduplication.  :)  (And
probably a few others.)

Something like SurveyMonkey (http://www.surveymonkey.com) or
SurveyGizmo (http://www.surveygizmo.com) or similar would be better,
as it does all the reporting for you, builds the nice survey interface
with checkboxes, radio buttons, text fields, etc.  And they're still
free (as in beer).

OK, SurveyGizmo it will be.

I'll cook up a first version and give access to the account to whoever
wants to review it before it is officially on air.

Hi,

please add:

[ ] user quotas
[ ] subvolume quotas
[ ] delta backup (like zfs send)
[ ] raid5 (raidz1)
[ ] raid6 (raidz2)
[ ] raid7 (raidz3)
[ ] nfs4 acls
[ ] readonly snapshots
[ ] .snapshot gate in every directory to all snapshots (like netapps wa=
fl)

Yes, I would like to substitute some opensolaris servers and netapps wi=
th linux+btrfs :-)

Thanx,
Martin

I would add as well :

[ ] encryption (LUKS-like)

Here is a link to a preview of the survey. It is NOT published yet.

Hi Francis,

have you posted the URL yet?
I can't see it, does anybody else can see the link? :)

Thanks.
