Re: [ovirt-users] Any way to correlate a VM disk (e.g. /dev/vda) to the vdsm ovirt disk?

Right? All you know is on which storage domain is your virtual disk stored and disk uuid (imgUUID)), right? My approach is this (I am using block device based FC stroage so my virtual disks are stored as logical volumes). Probably there is much easier way ;-) please correct me ssh to any host list storage domains (sdUUID) vdsClient -s 0 getImageDomainsList find your domain uuid by name vdsClient -s 0 getStorageDomainInfo sdUUID you will get also pool (spUUID) now you can search for volume(s) the image consists of getVolumesList sdUUID spUUID imgUUID you will get volUUID (one or more) now you can check volume info getVolumeInfo sdUUID spUUID imgUUID volUUID and also you can get volume path getVolumePath sdUUID spUUID imgUUID volUUID

you will get something like /rhev/data-center/mnt/blockSD/088e7ed9-84c7-4fbd-a570-f37fa986a772/images/be5c56de-6a22-4d1a-8579-f0f5d501d90c/0681822f-3ac8-473b-95ce-380f8ab4de06 it is symlink which points to target block device it looks to me that on block devices the path is /dev/sdUUID/volUUID btw. I am using oVirt3.5...
