The last time i tried using SHAREDFS, i started from createStorageDomain verb, and it works fine. But now we have connectStorageServer verb... which i believe is the new way of doing things ? If i start from connectStorageServer verb to mount using SHAREDFS ( which goes via PosixFs... MountConnection flow), that won't help me entirely here, right ? Because it only mounts based on the dict sent, but does not do anything with the image and metadata stuff ( which createStorageDomain flow did ). I am wondering if its too early to start using connectStorageServer ? If not, how can i re-write the above vdsm standalone example using connectStorageServer instead of createStorageDomain flow ? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Will a solution via engine (i.e - create PosixFS storage domain) be good for you? Well, no. I kind of mis-interpreted the problem. My Q stands canceled. The right way indeed is to use createStorageServer followed by createStorageDomain, which i was confused initially a bit, but now its cleared. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Great, let me start and get back if i land up into issues. thanks for the pointer. Let us know if you need further assistance.. This is how I plan to attack it... using vdscli, let me know if my steps are correct ? 1) Use createStorageDomain to create a SHAREDFS_DOMAIN of domTypes data iso 2) Use createStoragePool and associate the above sd's with this pool. 3) How to copy .iso into the newly create iso dom ? engine-iso-uploader won't know abt it, rite ? I would've used `cp` (chown to make sure vdsm can read it when needed). engine-iso-uploader create the needed dir structure (metadata, images, dom_md etc) and put the .iso in the right dir. Using `cp` I will have to do that myself, rite ? 4) create a volume to represent my vm disk 5) Use create to create a VM and run it Is this the recommended way ( to use individual vdscli cmds) or the way its done in http://www.ovirt.org/wiki/Vdsm_Standalone ? For human-triggered setup, running vdsClient from bash may be easier. But the suggested python script is expected to take you slightly further on the road to reproducible testable application on top of Vdsm. If you have that python script working for LOCALFS, I'd suggest you try making it work for SHAREDFS too. Thanks, will try using the python script itself. When i use the script and create LOCALFS (and SHAREDFS in future) will these domains and hence VMs created on top of these domains be visible and manageable from OE side ? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
