Issue migrating hard drive to new vm store
by Bryan Sockel 14 Nov '17

14 Nov '17

Having an issue moving a hard disk from one vm data store new a newly created gluster data store. I can shut down the machine and copy the hard drive, detach the old hard drive and attach the new hard drive, but i would prefer to keep the vm on line when moving the disk. I have attached a portion of the vdsm.log file. Thanks Bryan

by andreil1＠starlett.lv 14 Nov '17

Hi, I'm trying to upload iso with this coomand. engine-iso-uploader --ssh-user=root --iso-domain=iso upload suse.iso Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): This go OK. However, then it asks root password, I enter it, then it asks again and again. Root password is correct for sure, becuase I can coonect vis ssh from terminal. How to fix this problem? May be its possible just to copy files manually? Thanks in advance. Andrei

Host Power Management Configuration questions
by Artem Tambovskiy 14 Nov '17

14 Nov '17

Trying to configure power management for a certain host and fence agent always fail when I'm pressing Test button. At the same time from command line on the same host all looks good: [root@ovirt ~]# fence_ipmilan -a 172.16.22.1 -l user -p pwd -o status -v -P Executing: /usr/bin/ipmitool -I lanplus -H 172.16.22.1 -p 623 -U user -P pwd -L ADMINISTRATOR chassis power status 0 Chassis Power is on Status: ON [root@ovirt ~]# What could be the reason? Regards, Artem

Transfer from one Storage to Other is very slow
by Jon bae 14 Nov '17

14 Nov '17

Hello everybody, I have a node where I installed nfs storage and I have a second nfs network storage. My node have a bond (4) with two nics and the other storage have a bond with 4 nics. My oVirt engine runs as a VM on my network storage. The bond on the node side is relative new, before I had this setup, the speed was good. But at the same time I also move my ovirt engine from a third server to the network storage. My problem is now, when I move a VM disk from the network storage to the storage on the node, I have very pure speed. A VM with 140GB takes more then an hour to transfer. When I make speed tests with iperf3 I got this speed: - from oVirt to network storage: 20Gbits/s - from network storage to node storage: 9.5Gbits/s - from ovrit to node storage 9.5 Gbits/s When I transfer a VM disk, iftop shows almost no traffic. Have you an idea what is happen here? Regards Jonathan

Issue with hosted engine restore.
by Krzysztof Wajda 14 Nov '17

14 Nov '17

Hello, I have to restore Hosted Engine on another host (completely new hardware). Based on this https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restori… is not clear for me if vm's will be rebooted during synchronization hosts with engine ? I have 5 hosts + 1 completely fresh. On host1 I have HE and there is no vm's on other 4 (host1-4) there are around 400 vm which can't be rebooted. Host5 for restore HE. Kris

recommendations for best performance and reliability
by Rudi Ahlers 14 Nov '17

14 Nov '17

Hi, Can someone please give me some pointers, what would be the best setup for performance and reliability? We have the following hardware setup: 3x Supermicro server with following features per server: 128GB RAM 4x 8TB SATA HDD 2x SSD drives (intel_ssdsc2ba400g4 - 400GB DC S3710) 2x 12 core CPU (Intel(R) Xeon(R) CPU E5-2650 v4 @ 2.20GHz Quad port 10Gbe Inter NIC 2x 10GB Cisco switches (to isolate storage network from LAN) One of the servers will be in another office, with a 600Mb wireless link for Disaster Recovery. What is recommended for the best setup in terms of redundancy and speed? I am guessing GlusterFS with a Distributed Striped Replicated Volume across 3 of the servers. For added performance I want to use the SSD drives, perhaps with dm-cache? Should I combine the 4x HDD's using LVM on each host node? What about RAID 6? Virtual Machines will then reside on the oVirt Cluster and any one of the 3 host nodes can fail, or any single HDD can fail and all should still work, right/? -- Kind Regards Rudi Ahlers Website: http://www.rudiahlers.co.za

Usually db is inside the engine vm. Is a postgres. Deleting it is not a problem, engine installation tools should recreate itt.
