[Engine-devel] vfs_type not being sent by engine to VDSM for GLUSTER DOMAIN case

[Deepak C Shetty]

I by mistake sent this earlier to users at ovirt
I think the right list is engine-devel, hence resending. Sorry for the 
mispost earlier.

Hi All,
     I am validating GLUSTERFS Storage domain engine patches (worked on 
by Sharad, in Cc) as posted here...
http://gerrit.ovirt.org/#/q/status:open+project:ovirt-engine+branch:master+topic:glusterfs,n,z
against VDSM Glusterfs domain support (already upstream in VDSM)

I see the below issue as part of me creatign a new Gluster Storage 
DOmain in the UI

VDSM doesn't recv. the vfs_type in the conList dict !!!

I had this small chat with Saggi of VDSM, just to confirm that there 
isn't a possibility that VDSM might be stripping args that are recd. 
from Engine.. and it doesn't.

<deepakcs> saggi, Hi
<saggi> deepakcs: hi

<deepakcs> saggi, Is it possible that VDSM might strip down some of the 
connparams that are recd. as part of connectStorageServer ?
<deepakcs> saggi, In engine log for GLUSTERFS_DOMAIN i see vfsType being 
passed, but connectStorageServer log doesn't show vfs_type in the params 
dict
<deepakcs> saggi, so wodering where vfs_type is getting dropped in this 
whole process
<saggi> Probably not being sent
<saggi> if it's not being logged
<deepakcs> saggi, engine log has this....

<deepakcs> saggi,  on VDSM side i see this...

<saggi> Then you are not sending the correct connection type

<deepakcs> saggi, 'you' means the engine side of code ? engine patches 
is being done by Sharad, and I amtrying to work with them on this issue

<deepakcs> saggi, domType=7 is GLUSTERFS_DOMAIN, so its correct on that 
front
<saggi> If it show nfsRetrans you are using nfs which doesn't have a 
vfs_type argument
<deepakcs> saggi, but engine log says storageType = GLUSTERFS
<deepakcs> saggi, maybe i can send mail to users at ovirt list to see if 
anybody can provide more clues
<deepakcs> saggi, but definitely this doesn't looks like a vdsm side of 
issue rite ?
<saggi> We log the params as we get them

<deepakcs> saggi, right, thats what i also see.. just wanted to confirm 
once with you, before i sent mail to ovirt folks

---------------------------------------------------------------------------------------------------------------------


Can someone help provide any clues on what might be the issue here ?
Because VDSM doesn't see vfs_type, the connectStorageServer fails and 
hence new SD cannot be created !

thanx,
deepak
