Hosted engine datastore crashed on adding a new datastore
by Klas Mattsson 25 Apr '14

25 Apr '14

Hello all, For some reason, when I try to add a second datastore (separate IP and empty share with 36:36 user rights), the share which has got the hosted-engine on it crashes. This of course crashes the hosted engine. When the share is up again, it's not sufficient to create a directory /rhev/data-center/mnt/ with identical name as before and mounting the share there. The hosted-engine still refuses to boot up. The load (pure I/O) on the NFS server goes up to about 11 as well. Any ideas on where I should check?

Storage domain - defining fields
by Gabi C 25 Apr '14

25 Apr '14

Hello! My setup 1 engine Fedora 19 ovirt 3.4 managing 3 nodes Fedora 19 + ovirt 3.4 updated; those nodes acts also as gluster server for 2 storage domains, each domain 3 bricks replicated ( so 3 bricks each). I have one questions regarding the fields one have to complete when defining a new storage domain and its importance. First, field "*Use Host*" - you have to complete with one of the nodes. Of course you can use any of the host in cluster, *but which is its significance/importance*? * If you reboot that node, you suppose to have any issue with the storage?* The same question with field "*Path*" - gluster case - "*Path to gluster volume to mount*" formatted as "HOST:VOLUME" , where host can be the same as above mentioned field- "*Use Host*" or any af the gluster cluster member; *which is its significance/importance?* *Again If you reboot that node, you suppose to have any issue with the storage?* My experience with rebooting these nodes*, *after moving VM's and putting it in Maintenance was good*,* until yesterday, when after such reboot I've got some corrupted VM images, and subsequently I had to restore them. Error message follows : Exit message: cannot read header '/rhev/data-center/mnt/glusterSD/10.125.1.194:gluster__data3/5fe658b1-43ff-4bfd-97d6-28217cf415df/images/321ad473-3741-4825-8ac0-6c416aa8f490/1a21454d-9931-4ed8-ba38-7126528664a1': Input/output error." Did I miss some step(s), beside moving VM's and puting node in maintenace, before reboot one host node, servig also as gluster node? Any hint, link would be appreciated! Thanks!

by Matt . 24 Apr '14

Hi All, I'm having an issue with oVirt 3.4 and Foreman 1.5 RC1 at the moment, it does not start/finish a new provisioned VM/Host., it creates it well on oVirt. I'm sure this worked well on a nightly some dags ago and I didn't update it after it. The foreman bug is shown here: http://projects.theforeman.org/issues/5132 What I also see in the engine log is a bunch of admin login errors which I cannot place anywhere: 2014-04-23 20:26:44,203 INFO [org.ovirt.engine.core.bll.LoginUserCommand] (ajp--127.0.0.1-8702-6) Running command: LoginUserCommand internal: false. 2014-04-23 20:26:44,242 INFO [org.ovirt.engine.core.bll.LogoutUserCommand] (ajp--127.0.0.1-8702-6) [2e4a8183] Running command: LogoutUserCommand internal: false. 2014-04-23 20:26:44,276 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-6) [2e4a8183] Correlation ID: 2e4a8183, Call Stack: null, Custom Event ID: -1, Message: User admin logged out. 2014-04-23 20:26:44,470 INFO [org.ovirt.engine.core.bll.LoginUserCommand] (ajp--127.0.0.1-8702-1) Running command: LoginUserCommand internal: false. 2014-04-23 20:26:44,510 INFO [org.ovirt.engine.core.bll.LogoutUserCommand] (ajp--127.0.0.1-8702-1) [5d731a43] Running command: LogoutUserCommand internal: false. 2014-04-23 20:26:44,542 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-1) [5d731a43] Correlation ID: 5d731a43, Call Stack: null, Custom Event ID: -1, Message: User admin logged out. 2014-04-23 20:26:44,575 INFO [org.ovirt.engine.core.bll.LoginUserCommand] (ajp--127.0.0.1-8702-3) Running command: LoginUserCommand internal: false. 2014-04-23 20:26:44,623 INFO [org.ovirt.engine.core.bll.RemoveVmCommand] (ajp--127.0.0.1-8702-3) [708f0b9a] Lock Acquired to object EngineLock [exclusiveLocks= key: 7bfc175c-dbcd-43c9-9549-cde8d3b3b731 value: VM I get the feeling this has something todo with eachother.

Hi, all I created DC, use GlusterFS as the domain type. And created Storage, with storage type "Data/GlusterFS" But VM used FUSE mount point, are not used qemu-glusterfs native integration When i looked at the running KVM processes, i saw -drive file=/rhev/data-center/mnt/ glusterSD/vdsm01.cn.local: local/35c541ad-bd48-4000-ad8f-8539629b7d75/images/9f3ecc5d-5d82-4e83-a89e-b298725e1d63/6a621ecc-715d-4a15-982c-05c618eefd36 But I expect to see -drive file=gluster+tcp:// Fodora 19 oVirt 3.3.4 libvirt 1.0.5 qemu-kvm 1.4.2

Is there any way to accomplish this? Like this, using php or python to post username, password and domain to the user portal. Is re-build and keep the cookie possible?

Spurious error message when the RHEV capacity is maxed out?
by Satya Vempati 24 Apr '14

24 Apr '14

--_000_CF7D45AF5E0Esvempatitintricom_ Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable We have about 900 vms in a RHEV-M 3.3 installation (3.3.2-0.50.el6ev) with = three hosts. Each VM has 1 socket, 1 core for CPU and 256 MB memory and 2 x 1TB disks + = one 5 GB boot disk. Each host has 2 cpu sockets with 4 cpu cores per socket. When we power on about 250 of these vms, we cannot power on any more vms. Attempting to do so gets the error (in the RHEV-M) console. Bad volume specification {'index': 0, 'iface': 'virtio', 'reqsize': '0', 'f= ormat': 'raw', 'bootOrder': '1', 'volumeID': '14aa7302-7f6d-4b80-922d-3fc09= 0695447', 'apparentsize': '5368709120', 'imageID': '97b1985e-e507-4927-91e9= -7393c7777de5', 'specParams': {}, 'readonly': 'false', 'domainID': '0c7abcc= c-1b97-4b39-ab96-e977a19fac3a', 'optional': 'false', 'deviceId': '97b1985e-= e507-4927-91e9-7393c7777de5', 'truesize': '0', 'poolID': '5849b030-626e-47c= b-ad90-3ce782d831b3', 'device': 'disk', 'shared': 'false', 'propagateErrors= ': 'off', 'type': 'disk'}. This looks like a spurious error, as we can power on the same VM after rebo= oting the hosts. And also, the hosts do not really look maxed out (CPU usage is around 25%, = memory around 50%), but no more vm=92s can be powered on. I was looking for a sizing guide, and found only https://access.redhat.com/= site/sites/default/files/attachments/rhev_sizing_0812.pdf Is there any other information available? --_000_CF7D45AF5E0Esvempatitintricom_ Content-Type: text/html; charset="Windows-1252" Content-ID: <43C5516411658D4E88AF942223A80EF2@internal> Content-Transfer-Encoding: quoted-printable <html> <head> <meta http-equiv=3D"Content-Type" content=3D"text/html; charset=3DWindows-1= 252"> </head> <body style=3D"word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-lin= e-break: after-white-space; color: rgb(0, 0, 0); font-size: 14px; font-fami= ly: Calibri, sans-serif;"> <div>We have about 900 vms in a RHEV-M 3.3 installation (<span style=3D"col= or: rgb(17, 17, 17); font-family: Verdana; line-height: 24px;">3.3.2-0.50.e= l6ev) </span>with three hosts.</div> <div><br> </div> <div>Each VM has 1 socket, 1 core for CPU and 256 MB memory and 2 x 1TB dis= ks + one 5 GB boot disk.</div> <div><br> </div> <div>Each host has 2 cpu sockets with 4 cpu cores per socket.</div> <div><br> </div> <div>When we power on about 250 of these vms, we cannot power on any more v= ms.</div> <div><br> </div> <div>Attempting to do so gets the error (in the RHEV-M) console.</div> <div><br> </div> <div> <div>Bad volume specification {'index': 0, 'iface': 'virtio', 'reqsize': '0= ', 'format': 'raw', 'bootOrder': '1', 'volumeID': '14aa7302-7f6d-4b80-922d-= 3fc090695447', 'apparentsize': '5368709120', 'imageID': '97b1985e-e507-4927= -91e9-7393c7777de5', 'specParams': {}, 'readonly': 'false', 'domainID': '0c7abccc-1b97-4b39-ab96-e977a19fac3a= ', 'optional': 'false', 'deviceId': '97b1985e-e507-4927-91e9-7393c7777de5',= 'truesize': '0', 'poolID': '5849b030-626e-47cb-ad90-3ce782d831b3', 'device= ': 'disk', 'shared': 'false', 'propagateErrors': 'off', 'type': 'disk'}.</div> </div> <div><br> </div> <div>This looks like a spurious error, as we can power on the same VM after= rebooting the hosts.</div> <div><br> </div> <div>And also, the hosts do not really look maxed out (CPU usage is around = 25%, memory around 50%), but no more vm=92s can be powered on. </div> <div><br> </div> <div>I was looking for a sizing guide, and found only <a href=3D"https= ://access.redhat.com/site/sites/default/files/attachments/rhev_sizing_0812.= pdf" style=3D"font-size: medium; color: rgb(102, 51, 102);">https://access.= redhat.com/site/sites/default/files/attachments/rhev_sizing_0812.pdf</a></d= iv> <div><br> </div> <div>Is there any other information available?</div> <br> </body> </html> --_000_CF7D45AF5E0Esvempatitintricom_--
