ceph-deploy progress and CDS session

ceph-deploy progress and CDS session

[Sage Weil]

There is a session at CDS scheduled to discuss ceph-deploy (4:40pm PDT on 
Monday).  We'll be going over what we currently have in backlog for 
improvements, but if you have any opinions about what else ceph-deploy 
should or should not do or areas where it is problematic, please reply to 
this thread to let us know what you think, and/or join the CDS discussion 
hangout.

For those who haven't noticed, we now have a full-time devoloper,
Alfredo Deza, who is working on ceph-deploy.  He's been making huge
progress over the last couple of weeks improving error reporting,
visibility into what ceph-deploy is doing, and fixing various bugs.  We
have a long list of things we want to do with the tool, but any feedback
from users is helpful to make sure we're working on the right things 
first!

There should be a like button for emails too, so that I can like Sage's
update on ceph-deploy. :)

Hi,

First I would like to state that with all its limitiation, I have 
managed to build multiple
clusters with ceph-deploy and without it, I would have been totally 
lost.  Things
that I feel would improve it include:

A debug mode where it lists everything it is doing.  This will be 
helpful in the future
when I move to a more integrated tool then ceph-deploy, as I could see 
exactly
how ceph-deploy built my test cluster.

To understand more types of linux storage devices. I have spent hours 
trying to make it
understand multipath devices, as I happen to have a large number of 
these in my lab,
but so far I have not made it work.

Really good documentation on all the ceph-deploy options.

Lastly, this is not just a ceph-deploy thing, but documentation 
explaining how things
boot up, and interact.  Ceph-deploy depends on tools like ceph-disk to 
mount OSD
disks on the servers during boot, and I learned the hard way that if a 
OSD is on a LUN
that is seen by more then one OSD node, you can corrupt data, as each 
OSD node
tries to mount all the ODS it can find.

One thing that comes to mind is the ability to create (or activate) 
osd's with a custom crush specification from (say) a supplied file.
