Can you try again @cibinsb ? Problem found and fixed.

@cibinsb
Thanks @cure, Its working now
Ward Vandewege
@cure
excellent! thanks for confirming. We'll be adding some monitoring of the package repositories to make sure this (missing published packages in the stable repo) does not happen again.

Hi all - I'm going through the users guide and discovered a discrepency in steps. Specifically https://doc.arvados.org/v2.2/user/tutorials/wgs-tutorial.html, from step 3a setting up a new project to step 3b working with collections. There is no transition.
EDIT: Nevermind, its there, just wasn't clear as II was reading it.

hi @golharam
Peter Amstutz
@tetron
we'll take that as feedback to improve the tutorial text
we have a ticket of details to polish in the tutorial, I added your comment https://dev.arvados.org/issues/17846

Hi all... Coming back with Arvados... I would like to know if the "Multi host Arvados" is posible for a provate network, tahts is, to install all of the services for a storage managment, using somne local CA certificates? That's because i have to proove on my staff that Arvados is viable, to have some public ip....
Peter Amstutz
@tetron
yes, you can use a local CA for your certificates

I've seen multiple references to https://gitlab.com/iidsgt/arv-helm but that returns 404 ; where did that get moved to?

@tetron
maybe @osmanwa knows?

@GuduleJR_twitter
@tetron ok, thank's I supose I have to use salt to autoticaly transfer the certificates to each servers....

Hi all,

We are currently setting up a test Arvados cluster and I ran into some unusual behaviour regarding the default replication number: even though I have set this number to 1 in config.yml (Clusters.ClusterID.Collections.DefaultReplication), and this is confirmed in the output of http://ClusterID.our.domain.com/arvados/v1/config, this does not appear to be replicated in the Python SDK:

$ /usr/share/python3/dist/python3-arvados-python-client/bin/python
Python 3.8.10 (default, Jun  2 2021, 10:49:15) 
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import arvados
>>> arvados.api('v1')._rootDesc['defaultCollectionReplication']
2

Any thoughts on why this happens? Thanks in advance!!

good catch, let me see

thanks Peter

oh, perhaps you have a cached discovery document?
Tom Schoonjans
@tschoonj
not sure what that is
I actually ran into this problem through arv-put

rm -r ~/.cache/arvados
Tom Schoonjans
@tschoonj
ok
this works!
thanks Peter!!

Hello again,

We are still setting up our test arvados infrastructure, and have now a single VM with API server, PostgreSQL, keepstore and keepproxy. Our issue now is with the keepproxy: the docs stipulate that arv keep_service accessible should contain a reference to the keepproxy server. This works fine when running the command on the office network, but fails when trying this from home over VPN as it is shown to contain the keepstore domain name instead.

I assume that this is related to the geo settings in the nginx config?

Thanks in advance!

Peter Amstutz
@tetron
yes
it is controlled by the geo setting
is the home VPN considered to be on the same network?
Tom Schoonjans
@tschoonj
apparently not :-)
I will ask our IT department what IP range we need to add to support our VPN connections
Peter Amstutz
@tetron
if you are outside the private network, you should get keepproxy from "keep_services accessible", if you are inside the private network, you should get the keepstore servers instead. it doesn't matter which one you get as long as it is reachable
so it sounds like either the keepstore needs to be reachable from the home VPN or your geo section needs to send the home VPN to keepproxy (which needs to be reachable?)
Tom Schoonjans
@tschoonj
aha
so what we are seeing here is actually ok?
Peter Amstutz
@tetron
does it work?
does arv-get work?
Tom Schoonjans
@tschoonj
my colleague on VPN just tested arv-put and that fails
Peter Amstutz
@tetron
well so either all the keepstore servers, or the keepproxy server, need to be reachable by home VPN
so you need to figure that out first
the one particular advantage of using keepproxy in this case, if you have keepstore-level replication enabled, it'll handle replicating the upload at the keepproxy level instead of the client having to send data twice
Tom Schoonjans
@tschoonj
ok thanks will investigate
Peter Amstutz
@tetron
however if you arn't using keepstore level replication (DefaultReplication: 1) and using replication at a lower level (object store or RAID) then it doesn't matter
Tom Schoonjans
@tschoonj
yes, we are using DefaultReplication: 1 in this setup
Peter Amstutz
@tetron
ok then you just need to figure out where the VPN fits in your network topology
Tom Schoonjans
@tschoonj
Ok, we got it fixed now. The proxy is now used everywhere except when using arv on the arvados VM itself
Andrey Kartashov
@portah
@tetron Does arvados have a preinstalled version on a cloud?
Peter Amstutz
@tetron
@portah to try it out or to do real workloads?
Andrey Kartashov
@portah
@tetron to check api and try with cwl
