I want to correlate virtual disks back to their originating storage under
ovirt. Is there any way to do this?
e.g. (made up example)
/dev/vda
maps to ovirt disk
disk1_vm serial 978e00a3-b4c9-4962-bc4f-ffc9267acdd8
7:43 a.m.
Hi ccox,
you can see the disk id mapping to device if you execute 'ls -l
/dev/disk/by-id/' .
Second way, and easier, is to make sure you have guest-agent installed on
your guest virtual machine and using rest API you can run GET command:
GET on .../api/vms/{vm_id}/disks
You will see an attribute called "<logical_name>" .
I hope that helps
Thanks,

should have said I'm running 3.4. I don't think there's a logical_name in
that version. And by-id or by-uuid doesn't seem to match anything.
Maybe this can't be done in 3.4?
8:51 p.m.
You are right, there is no logical_name attr in disk object before 3.5 [1]

Can you share the ouput of:
tree /dev/disk
On the guest?
And the output of
pvscan --cache
lvs -o vg_name,name,tags
On the host?
On the guest, the the disk serial number should be the first 20
characters of the disk
uuid (I think it is the image uuid in vdsm terms, or disk uuid in engine terms).
The image uuid should appear in a lv tag on the host, and the prefix
of this uuid should
be found on the guest.
Can you describe why do you need this information?

Hi,
Dne 6.10.2015 v 22:07 ccox(a)endlessnow.com napsal(a):
I want to correlate virtual disks back to their originating storage
und=
er
ovirt. Is there any way to do this?
e.g. (made up example)
/dev/vda
maps to ovirt disk
disk1_vm serial 978e00a3-b4c9-4962-bc4f-ffc9267acdd8
In oVirt there are two storage types - filesystem based (NFS, posix,=20
glusterfs - uses files for storing images) and block device based (FC,=20
iSCSI - uses lvm)
If I understand correctly, you would like know where exactly is stored a =
virtual disk. Right?
All you know is on which storage domain is your virtual disk stored and=20
disk uuid (imgUUID)), right?
My approach is this (I am using block device based FC stroage so my=20
virtual disks are stored as logical volumes). Probably there is much=20
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-380f8ab4de0=
6
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...
Cheers, Jiri

In oVirt there are two storage types - filesystem based (NFS, posix,
glusterfs - uses files for storing images) and block device based (FC, iSCSI
- uses lvm)
If I understand correctly, you would like know where exactly is stored a
virtual 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
Note that getVolumePath was removed in 3.6. The only way to get this
info now is via prepareImage.
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...
