    @mikegcoleman is that exactly the same one on severalnines.com?

    @mikegcoleman
    I am literally cutting and pasting from servalnines - the only thing I change is the replicas=
    Chanwit Kaewkasi
    @chanwit
    I see
    so probably I forgot to set size on the discovery url and etcd kept falling
    thank you Mike
    Mike Coleman
    @mikegcoleman
    size on discovery url specifies how many nodes will be in the etcd cluster right?
    Chanwit Kaewkasi
    @chanwit
    yes that's right and I forgot to pass it (size=x)
    then the key for cluster size didn't exist
    and etcd needs that key
    Mike Coleman
    @mikegcoleman
    yep. I missed that the first two times I tried

    @chanwit
    oh right. Andrea asked me during Swarm2K that he wanted to get pprof from the managers but I dont know how to do it.
    @mikegcoleman and @mgoelzer do you know how to do that?
    Mike Coleman
    @mikegcoleman

    Hell, I for some reasons I registered Wed on my mind LOL. Abord :-p

    @chanwit
    we can play a bit

    @_pascalandy_twitter
    sure

    Description ? - Swarm3k

    net.ipv4.neigh.default.gc_thresh1 = 30000
    net.ipv4.neigh.default.gc_thresh2 = 32000
    net.ipv4.neigh.default.gc_thresh3 = 32768
    I never saw anything related to this config. What is it for ?
    Chanwit Kaewkasi
    @chanwit
    please add these 3 lines into that file
    it's to make Wordpress and MySQL Galera stable together
    a network engineer told us that the default network config not handle ARP well
    and this gc threshold setting would help
    Pascal Andy
    @_pascalandy_twitter
    OK!
    If you want, you can use my nodes for few hours
    but I can't be pro-active at the moment
    Chanwit Kaewkasi
    @chanwit
    not sure if I can provision manager during this time
    may be could you please alpine top one of them to see how many containers can fit a single node?
    Pascal Andy
    @_pascalandy_twitter
    I can do it
    let's use team viewer. Cool ?
    Chanwit Kaewkasi
    @chanwit
    so we can use your info as the base line to calculate how many containers we can start for 3,000 nodes
    Pascal Andy
    @_pascalandy_twitter
    make sense :)
    let's continue via DM on twitter
    Chanwit Kaewkasi
    @chanwit
    OK

    @sujaypillai
    just curious how to add this line - net.ipv4.neigh.default.gc_thresh1 = 30000 into the node that will be created
