ovirt 4.1 : Can't deploy second node on self hosted engine cluster and host with hosted engine deployed (and also hosted engine VM) is not added to interface
by yayo (j) 07 Jul '17

07 Jul '17

Hi at all, I have correctly deployed an hosted engine using node01 via: hosted-engine --deploy Using FC shared storage. Seems all work good but, when I login in to the ovirt web interface I can't find the hosted engine under the VM tab (also the node01 server). So, I have tried to add node02 (no problem) and added the "Data Domain" storage (another FC share storage). Now (I Think) I needs to deploy also here the hosted engine but I can't. There is only one way, to put node02 in maintenance mode but, after that, "Data Domain" added going down and, when I try to deploy the hosted engine interface says: Error while executing action: node02: Cannot edit Host. You are using an unmanaged hosted engine VM. Please add the first storage domain in order to start the hosted engine import process. what is this "first storage domain"? I have not added the node01 yet because last time hosted engine crashed and the only way was to restart the installation .... Note: Hosted engine seems to be correcty deployed because all work good, but deploy script ended with error: [ INFO ] Engine-setup successfully completed [ INFO ] Engine is still unreachable [ INFO ] Engine is still not reachable, waiting... [more of these messages] [ ERROR ] Engine is still not reachable [ ERROR ] Failed to execute stage 'Closing up': Engine is still not reachable [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20170123113113.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Hosted Engine deployment failed: this system is not reliable, please check the issue,fix and redeploy Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20170123105043-kvzx84.log Is related to this bug? https://bugzilla.redhat.com/show_bug.cgi?id=1415822

07 Jul '17

Hi, I am trying to import a windows OVA file. Ovirt engine is up and running. The target storage domain is going to be glusterfs storage domain. Is there any documentation that can be looked at to achieve this. Thanks and Regards, Ram

user permissions
by Fabrice Bacchella 07 Jul '17

07 Jul '17

I'm trying to give a user the permissions to stop/start a specific server. This user is given the generic UserRole for the System. I tried to give him the roles : UserVmManager UserVmRunTimeManager UserInstanceManager InstanceCreator UserRole for that specific VM, I always get: query execution failed due to insufficient permissions. As soon as I give him the SuperUser role, he can stop/start it. What role should I give him for that VM ? I don't want to give the privilege to destroy the vm, or add disks. But he should be able to change the os settings too.

How to create a new Gluster volume
by Gianluca Cecchi 07 Jul '17

07 Jul '17

Hello, I'm trying to create a new volume. I'm in 4.1.2 I'm following these indications: http://www.ovirt.org/documentation/admin-guide/chap-Working_with_Gluster_St… When I click the "add brick" button, I don't see anything in "Brick Directory" dropdown field and I cannot manuall input a directory name. On the 3 nodes I already have formatted and mounted fs [root@ovirt01 ~]# df -h /gluster/brick3/ Filesystem Size Used Avail Use% Mounted on /dev/mapper/gluster-export 50G 33M 50G 1% /gluster/brick3 [root@ovirt01 ~]# The guide tells 7. Click the Add Bricks button to select bricks to add to the volume. Bricks must be created externally on the Gluster Storage nodes. What does it mean with "created externally"? The next step from os point would be volume creation but it is indeed what I would like to do from the gui... Thanks, Gianluca

Cloning VM on NFS Leads to Locked Disks
by Charles Tassell 06 Jul '17

06 Jul '17

Hi Everyone, I'm having some issues with my oVirt 4.1 (fully updated to latest release as of yesterday) cluster. When I clone a VM the disks of both the original and the clone stay in the locked state, and the only way I can resolve it is to go into the database on the engine and run "update images set imagestatus=1 where imagestatus=2;" I'm using NFS4 as a datastore and the disks seem to copy fine (file sizes match and everything), but the locking worries me. To clone the VM I just shut the source VM down and then right click on it and select "Clone" I've attached the full VDSM log from my last attempt, but here is the excerpt of the lines just referencing the two disks (d73206ed-89ba-48a9-82ff-c107c1af60f0 is the original VMs disk and 670a7b20-fecd-45c6-af5c-3c7b98258224 is the clone.) 2017-05-10 11:36:20,120-0300 INFO (jsonrpc/2) [dispatcher] Run and protect: copyImage(sdUUID=u'20423d5e-188c-4e10-9893-588ceb81b354', spUUID=u'00000001-0001-0001-0001-000000000311', vmUUID='', srcImgUUID=u'd73206ed-89ba-48a9-82ff-c107c1af60f0', srcVolUUID=u'bba1813d-9e91-4e37-bed7-40beedda8051', dstImgUUID=u'670a7b20-fecd-45c6-af5c-3c7b98258224', dstVolUUID=u'013d8855-4e49-4984-8266-6a5e9437dff7', description=u'', dstSdUUID=u'20423d5e-188c-4e10-9893-588ceb81b354', volType=8, volFormat=5, preallocate=2, postZero=u'false', force=u'false', discard=False) (logUtils:51) 2017-05-10 11:36:20,152-0300 INFO (jsonrpc/2) [storage.Image] image d73206ed-89ba-48a9-82ff-c107c1af60f0 in domain 20423d5e-188c-4e10-9893-588ceb81b354 has vollist [u'bba1813d-9e91-4e37-bed7-40beedda8051'] (image:319) 2017-05-10 11:36:20,169-0300 INFO (jsonrpc/2) [storage.Image] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 imgUUID=d73206ed-89ba-48a9-82ff-c107c1af60f0 chain=[<storage.fileVolume.FileVolume object at 0x278e450>] (image:249) 2017-05-10 11:36:20,292-0300 INFO (tasks/0) [storage.Image] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 imgUUID=d73206ed-89ba-48a9-82ff-c107c1af60f0 chain=[<storage.fileVolume.FileVolume object at 0x302c6d0>] (image:249) 2017-05-10 11:36:20,295-0300 INFO (tasks/0) [storage.Image] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 vmUUID= srcImgUUID=d73206ed-89ba-48a9-82ff-c107c1af60f0 srcVolUUID=bba1813d-9e91-4e37-bed7-40beedda8051 dstImgUUID=670a7b20-fecd-45c6-af5c-3c7b98258224 dstVolUUID=013d8855-4e49-4984-8266-6a5e9437dff7 dstSdUUID=20423d5e-188c-4e10-9893-588ceb81b354 volType=8 volFormat=RAW preallocate=SPARSE force=False postZero=False discard=False (image:765) 2017-05-10 11:36:20,305-0300 INFO (tasks/0) [storage.Image] copy source 20423d5e-188c-4e10-9893-588ceb81b354:d73206ed-89ba-48a9-82ff-c107c1af60f0:bba1813d-9e91-4e37-bed7-40beedda8051 vol size 41943040 destination 20423d5e-188c-4e10-9893-588ceb81b354:670a7b20-fecd-45c6-af5c-3c7b98258224:013d8855-4e49-4984-8266-6a5e9437dff7 apparentsize 41943040 (image:815) 2017-05-10 11:36:20,306-0300 INFO (tasks/0) [storage.Image] image 670a7b20-fecd-45c6-af5c-3c7b98258224 in domain 20423d5e-188c-4e10-9893-588ceb81b354 has vollist [] (image:319) 2017-05-10 11:36:20,306-0300 INFO (tasks/0) [storage.Image] Create placeholder /rhev/data-center/00000001-0001-0001-0001-000000000311/20423d5e-188c-4e10-9893-588ceb81b354/images/670a7b20-fecd-45c6-af5c-3c7b98258224 for image's volumes (image:149) 2017-05-10 11:36:20,392-0300 INFO (tasks/0) [storage.Volume] Request to create RAW volume /rhev/data-center/00000001-0001-0001-0001-000000000311/20423d5e-188c-4e10-9893-588ceb81b354/images/670a7b20-fecd-45c6-af5c-3c7b98258224/013d8855-4e49-4984-8266-6a5e9437dff7 with size = 20480 sectors (fileVolume:439) 2017-05-10 11:37:58,453-0300 INFO (tasks/0) [storage.VolumeManifest] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 imgUUID=670a7b20-fecd-45c6-af5c-3c7b98258224 volUUID = 013d8855-4e49-4984-8266-6a5e9437dff7 legality = LEGAL (volume:393)

How to reset volume info in storage domain metadata LV

Recently I got a disk snapshot marked as illegal in an VM due to a failed live merge I fixed the snapshot manually with qemu-img rebase, now qemu-img check shows everything OK I also set the imagestatus to OK in the engine database, as shown below engine=# select image_guid,parentid,imagestatus,vm_snapshot_id,volume_type,volume_format,active from images where image_group_id='c35ccdc5-a256-4460-8dd2-9e639b8430e9'; image_guid | parentid | imagestatus | vm_snapshot_id | volume_type | volume_format | active --------------------------------------+--------------------------------------+-------------+--------------------------------------+------------- +---------------+-------- 07729f62-2cd2-45d0-993a-ec8d7fbb6ee0 | 00000000-0000-0000-0000-000000000000 | 1 | 7ae58a5b-eacf-4f6b-a06f-bda1d85170b5 | 1 | 5 | f ee733323-308a-40c8-95d4-b33ca6307362 | 07729f62-2cd2-45d0-993a-ec8d7fbb6ee0 | 1 | 2ae07078-cc48-4e20-a249-52d3f44082b4 | 2 | 4 | t But when I try to boot the VM it still fails with this error in the SPM Thread-292345::ERROR::2017-07-06 14:20:33,155::task::866::Storage.TaskManager.Task::(_setError) Task=`2d262a05-5a03-4ff9-8347-eaa22b6e143c`::Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 873, in _run return fn(*args, **kargs) File "/usr/share/vdsm/logUtils.py", line 49, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/storage/hsm.py", line 3227, in prepareImage raise se.prepareIllegalVolumeError(volUUID) prepareIllegalVolumeError: Cannot prepare illegal volume: ('ee733323-308a-40c8-95d4-b33ca6307362',) Thread-292345::DEBUG::2017-07-06 14:20:33,156::task::885::Storage.TaskManager.Task::(_run) Task=`2d262a05-5a03-4ff9-8347-eaa22b6e143c`::Task._run: 2d262a05-5a03-4ff9-8347-eaa22b6e143c (u'146dca57-05fd-4b3f-af8d-b253a7ca6f6e', u'00000001-0001-0001-0001-00000000014d', u'c35ccdc5-a256-4460-8dd2-9e639b8430e9', u'ee733323-308a-40c8-95d4-b33ca6307362') {} failed - stopping task Just before that error I see this operation in the log: /usr/bin/taskset --cpu-list 0-23 /usr/bin/dd iflag=direct skip=11 bs=512 if=/dev/146dca57-05fd-4b3f-af8d-b253a7ca6f6e/metadata count=1 If I run it manually I get this: [root@blade6 ~]# /usr/bin/taskset --cpu-list 0-23 /usr/bin/dd iflag=direct skip=11 bs=512 if=/dev/146dca57-05fd-4b3f-af8d-b253a7ca6f6e/metadata count=1 DOMAIN=146dca57-05fd-4b3f-af8d-b253a7ca6f6e VOLTYPE=LEAF CTIME=1497399380 FORMAT=COW IMAGE=c35ccdc5-a256-4460-8dd2-9e639b8430e9 DISKTYPE=2 PUUID=07729f62-2cd2-45d0-993a-ec8d7fbb6ee0 LEGALITY=ILLEGAL MTIME=0 POOL_UUID= SIZE=209715200 TYPE=SPARSE DESCRIPTION= EOF So I guess the volume info is cached in the storage domain's metadata LV, and it's still in ILLEGAL status there Is there a way to force ovirt to update the information in the metadata LV? Of course I've thought of updating manually with dd, with it seems too risky (and scary) to do it in production Salu2! -- Miguel Armas CanaryTek Consultoria y Sistemas SL http://www.canarytek.com/

Configure an ovirt 4.1 hosted engine using SAS storage (aka DAS storage)
by yayo (j) 06 Jul '17

06 Jul '17

Hi all, I'm tring to install a new cluster ovirt 4.1 (Centos 7) configured to use a SAN that expose LUN via SAS . When I start to deploy ovirt and the engine using "hosted-engine --deploy" the only options I have are: (glusterfs, iscsi, fc, nfs3, nfs4) There is no option for "local" storage (that are not local naturally, but are multipath device exposed by SAN via LUN) Can you help me? What is the right configuration? Thank you
