MVenesioHi Guys, i'm testing the generic driver with neutron and OVS using "handle share servers" enabled. Once the virtual instance is created and the agent can connect with it using ssh, i'm getting the next error "SSHException: Check whether private key or password are correctly set. Error connecting via ssh: not a valid EC private key file"15:28
MVenesioit seems like the key file isn't correct or is something wrong with paramiko trying to read it, any ideas ?15:29
MVenesioI'm using the image from the oficial git repo, and actually it seems like the instance does not even have cloud-init and is not trying to reach the metadata to get the key.15:34
MVenesioi'll try with user and password manila:manila15:35
*** lpetrut has quit IRC15:35
*** chlong has joined #openstack-manila15:39
*** belmoreira has quit IRC15:45
MVenesioit works fine using user and passw, so the image it's not prepared to use key-pairs15:48

bswartzMVenesio: which image exactly are you using? it should have cloudinit17:55
*** chlong has joined #openstack-manila17:55
MVenesiohttps://tarballs.openstack.org/manila-image-elements/images/manila-service-image-master.qcow217:57
bswartzyeah that's the standard image17:57
bswartzwhat makes you think it doesn't have cloudinit?17:57
MVenesiobswartz: when the instance boots i'm not seeing cloud init trying to reach the metadata17:58
bswartzMVenesio: https://github.com/openstack/manila-image-elements/blob/master/elements/manila-ssh/install.d/60-fetch-public-ssh-keys17:58
MVenesiobswartz: let me try launching an instance manually17:59
bswartzMVenesio: we've observed cases where the instance was unable to contact the metadata server due to network issues17:59
bswartzhowever if you see that it's not even trying then you may have found a bug18:00
MVenesiobswartz: exactly, let me check again manually and i'll let you know18:00
*** kaisers has quit IRC18:14
MVenesiobswartz: just to clarify, i've just donwloaded the image from that link and uploaded to glance, i've didn't ran any command to build it , is that ok ?18:14
*** kaisers has joined #openstack-manila18:14
bswartzyeah the link you sent is to the file that automatically gets uploaded by the build18:15
*** kaisers has quit IRC18:17
*** kaisers has joined #openstack-manila18:17
*** gouthamr has joined #openstack-manila18:24
MVenesiobswartz: metadata it's working, don't know why i'm not seeing the log  but its ok18:28
bswartzyou mean the SSH keys are getting installed so you can SSH in?18:28
*** catinth__ has quit IRC18:28
MVenesiobswartz: yes, launching an instance manually, setting my keys18:29
bswartzcool18:29
bswartzin that case you might just be encountering the network flakiness I alluded to earlier18:29
*** catintheroof has joined #openstack-manila18:30
bswartzit's a problem that occurs rarely in the gate, but we've never been able to rack down the exact reason18:30
MVenesiobswartz: i don't think is a network issue, since with user and password it works perfectly18:30
MVenesiobswartz: the instance is perfectly reachable, so the error "SSHException: Check whether private key or password are correctly set. Error connecting via ssh: not a valid EC private key file"18:30
MVenesioshould be related with some other stuff18:30
bswartzyeah the hypothesis we have is that the network is briefly nonfunctional during the window of time in the bootup sequence when it's trying to download the keys18:31
*** dsariel has quit IRC18:31
bswartzthe image only tries to get the keys during bootup, not again later on when the network does start working18:31
bswartzI'm not sure what might account for the network being briefly disrupted18:32
bswartzbut that's what the evidence points to18:32
MVenesiobswartz: ok let me do some tests about it, i'll try to launch the instance-share and once it failed, i'll try to attach a floating ip and use the keys to enter on it18:33
MVenesiobswartz: i want to be sure that the problem is not paramico reading the keys, or maybe not recognising the key files or something like that18:34

MVenesiobswartz: I was wrong with the instance test, i tested with the wrong instance19:46
MVenesiobswartz: the instance i've launched with the original image didn't work, and the reason is seems like fetch-public-ssh-keys.sh didn't executed19:47
MVenesiobswartz: i executed it by hand, and works perfectly19:49
bswartzMVenesio: what do you mean didn't execute?19:53
bswartzyou're confident that the script never ran?19:53
MVenesiobswartz: sorry, i mean  was not executed at boot time19:53
bswartzhmm I see a reference to "$DIB_INIT_SYSTEM" == "upstart" in there19:53
bswartzI wonder if that used to work correctly for trusty but no longer works for xeial19:54
bswartzxenial19:54
MVenesiobswartz: exactly, i'm using systemd19:54
bswartzthis could be a regression caused in the upgrade from trusty to xenial, and we never caught it because we've been using passwords since the aforementioned network issues made use of keys unreliable19:55
bswartzso this is a bug in manila-image-elements for sure then -- just need to figure out how to fix it to work with systemd19:56
MVenesiobswartz: why aren't you using cloud-init to get the keys ?19:56
bswartzMVenesio: I didn't write the image elements stuff to begin with19:59
bswartzit has a long history -- most likely the reason has to do with something from long ago which might not be true anymore19:59
bswartzthere was a desire to make sure the image was as small as possible though -- maybe cloud-init would have bloated it?20:00
*** chlong has quit IRC20:07
MVenesiobswartz: don't think so, the package is really light, about 100M20:23
bswartzI guess "small" and "light" are relative terms20:25
bswartzMy glance image is 6.4MB20:26
bswartzand it has support for getting the SSH key from the metadata server20:27
bswartzso I look at something that weighs 100MB and call it large20:27
*** chlong has joined #openstack-manila20:31
*** chlong has quit IRC20:41
MVenesiobswartz: you're right20:46
MVenesiobswartz: i'm having also some issues triying to allow access to my shares using the python-manilaclient for ubuntu20:47
bswartzwhat kind of issues?20:48
MVenesiobswartz: i'm using the  version 1.8.1-2, and i'm getting some errors like DEBUG (shell:648) "There is no such action: allow_access (HTTP 400) (Request-ID: req-83566473-3823-4d57-905d-24838718cb69)"20:48
bswartzerrr20:49
bswartznever seen something like that20:49
MVenesiobswartz: i'm using the official docs to do it : manila access-allow 3f706adb-3de9-430d-b2d6-5fdbb64d13a6 ip 0.0.0.0/0 --access-level rw20:49
bswartzyeah the problem seems lower level20:49
bswartzsomething at the REST API level is broken20:50
MVenesiocan't do access-allow or access-list  or nothing about access20:50
bswartzwhat client/server versions20:51
MVenesiobswartz: i can try doing the api calls directly20:51
bswartzif it's latest version of both then it's probably a config issue20:52
MVenesiobswartz: python-manilaclient  1.8.1-2 and the manila version of ubuntu xenial 1:2.0.0-0ubuntu120:53
bswartzoh20:53
bswartzinstalled with apt-get?20:53
bswartzI haven't tested that in a very long time20:53
MVenesiobswartz: i think its manila (2.0.0)20:53
bswartzI always install from pip or git20:53
bswartzI have to go AFK for dinner, I'll bbl to see if I can help more20:53
MVenesiobswartz: ok no problem i'll git clone and then reinstall using python install20:54
*** gouthamr has joined #openstack-manila20:54
MVenesiobswartz: i'm always try to follow the official guide first20:55
MVenesiobswartz: thanks for your help, i think i'll continue tomorrow20:55
