oVirt + gluster with JBOD
by Eduardo Mayoral 14 Sep '18

14 Sep '18

Hi! I am thinking about using some spare servers I have for a hyperconverged oVirt + gluster. Only problem with these servers is that the RAID card is not specially good, so I am considering using gluster in a JBOD configuration. JBOD is supported for recent versions of gluster, but I am not sure if this configuration is supported by oVirt, or if there are any special considerations I should take into account. Anyone running oVirt + gluster with JBOD who can comment on this? Thanks! -- Eduardo Mayoral.

OVIRT 4.2.6: Deploying Errors + Official Repository Problems
by jtorres＠bsc.es 13 Sep '18

13 Sep '18

Hi all, We are trying to install the new release of OVIRT 4.2.6 on freshly installed machines based on RHEL 7.5. First of all, we encountered a strange error when install the ovirt-release42 package, it adds the necessary public repositories on /etc/yum.repos.d/, but after do that, sometimes when we try to update or install the other required packages we saw: Cannot find a valid baseurl for repo: ovirt-4.2/$releasever Why cannot configure this path variable automatically or what can influence to obtain this problem? In the other hand, when the repos sometimes are well configured and we can install the packages correctly, we found other problems related to the deploy of the ovirt-engine (OVA appliance based). Trying through cockpit, we found this error: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": true, "cmd": ["virt-install", "-n", "HostedEngineLocal", "--os-variant", "rhel7", "--virt-type", "kvm", "--memory", "16348", "--vcpus", "4", "--network", "network=default,mac=00:16:3e:05:c3:66,model=virtio", "--disk", "/var/tmp/localvmj4Y_f1/images/65f7f081-4d9e-43ae-926f-25807f075f1d/a0a00e73-d3ea-4b9b-bd26-06fe189931f2", "--import", "--disk", "path=/var/tmp/localvmj4Y_f1/seed.iso,device=cdrom", "--noautoconsole", "--rng", "/dev/random", "--graphics", "vnc", "--video", "vga", "--sound", "none", "--controller", "usb,model=none", "--memballoon", "none", "--boot", "hd,menu=off", "--clock", "kvmclock_present=yes"], "delta": "0:00:02.122539", "end": "2018-09-06 00:44:18.089510", "msg": "non-zero return code", "rc": 1, "start": "2018-09-06 00:44:15.966971", "stderr": "/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.21.1) or chardet (2.2.1) doesn't match a supported version!\n RequestsDepen dencyWarning)\nERROR internal error: qemu unexpectedly closed the monitor: qemu: could not load PC BIOS 'bios-256k.bin'\nDomain installation does not appear to have been successful.\nIf it was, you can restart your domain by running:\n virsh --connect qemu:///system start HostedEngineLocal\notherwise, please restart your installation.", "stderr_lines": ["/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.21.1) or chardet (2.2.1) doesn't match a supported version!", " RequestsDependencyWarning)", "ERROR internal error: qemu unexpectedly closed the monitor: qemu: could not load PC BIOS 'bios-256k.bin'", "Domain installation does not appear to have been successful.", "If it was, you can restart your domain by running:", " virsh --connect qemu:///system start HostedEngineLocal", "otherwise, please restart your installation."], "stdout": "\nStarting install...", "stdout_lines": ["", "Starting install..."]} Seem that it's related to Python packages versions (urllib3 and chardet), but we wasn't sure about that. How could workaround this problem? Trying to install this libraries manually? We tried to found the same error over the Lists and Community, but we don't found some info about that. Thank for your help in advance. Regards!

Gluster deployment - Arbiter volume - different disk size - volumes sizes
by florentl 12 Sep '18

12 Sep '18

Hello, I have one more question for the gluster deployment. I have three servers with different disk sizes : - server1 : 3 x SSD configured in raid 5 mode for a total capacity of 900 GB - server2 : 6 x SSD configurerd in raid 6 mode for a total capacity of 2,2 TB - server3 : same as server2 (2,2TB) Because my server1 has less capacity than the others I will use it as an arbiter volume (during the deployment I will declare it as the last host : host3). Is-it correct ? So I will create 4 volumes : - engine : 50 GB type replicated without arbiter - data : ?? - vmstore : ??? - iso : 15 GB replicated with arbiter volume Can someone tell me what are the differences between data and vmstore volume ? In the earlier version there was only information about data volume and export volume. I found nothing about vmstore volume. If the wmstore is, as its name suggests, the place where all vm files will be stored including vm disks images, I think I have to set most of the capacity for this volume. So at the end my 4 volumes will be : - engine : 50 GB type replicated without arbiter - data : 500 TB replicated with arbiter volume - vmstore : 1,5 TB replicated with arbiter volume - iso : 15 GB replicated with arbiter volume What do you think of this ? Thanks, Florent

vm with disks on multiple glusterfs domains fails if a gluster host goes down
by g.vasilopoulos＠uoc.gr 12 Sep '18

12 Sep '18

It seems that a vm with 3 disks boot in domain engine another disk in domain vol1 and a third in domain v3 became non responsive when one gluster host went down. To explain a bit the situation I have 3 glusterfs hosts with 3 volumes hosts are g1,g2,g3 each have 3 bricks g1 has vol1,vol2 and vol3 arbiter g2 has vol1, vol2arbiter and vol3 g3 has vol1arb vol2 and vol3 libgfapi is enabled . I put a host in maintenance to update the bios and the vm who had disks in two domain became unresponsive.. is this normal? qemu logs showing that it tries Domain configuration shows host1 as primary for vol1 and host2 as primary for vol3 with the other two as backup-volfile servers.. it seems it always try to connect to the server that is down and not to one of the alternative hosts... is this libgapi/libvirt problem ? Here are some libvirt logs showing what it tries to do..

Install failing at DNS resolution check (closing up).
by Kristian Petersen 12 Sep '18

12 Sep '18

I am trying to set up a small oVirt 4.2 cluster on CentOS with 2 hosts to do some testing with. I got the everything set up to the point where I am running the hosted-engine --deploy, but it fails with an error saying it was unable to resolve some host name or IP address (but it isn't very clear what one). I have tested on the same machine its ability resolve the hosts in the cluster both forward and reverse and they work fine with nslookup. That includes the DNS entry for the hosted-engine. I tried putting them all into the /etc/hosts files of each computer but it still fails at the same step. Thge log file it refers to does not seem very helpful. Maybe I'm just not sure what to look for. -- Kristian Petersen System Administrator BYU Dept. of Chemistry and Biochemistry

Question on gluster sharding maturity/stability
by Brian Sipos 12 Sep '18

12 Sep '18

I'm currently running oVirt 4.1 (with gluster 3.8.15) and as this is a cluster which has been upgraded from (I believe) oVirt 3.5 originally, the storage volumes use old "Optimize for Virt Store" configuration of not enabling sharding. I see now that the oVirt 4.1 "optimize" configuration does enable sharding, but I am a bit wary after seeing some horror stories from about a year ago about corruptions and data loss caused by sharding in earlier gluster versions. Is the gluster associated with oVirt 4.1 now at a stable point that I can and should trust sharding? I plan on doing some simple experimenting first, but I see a great benefit to balancing distributed-replicated volumes and for healing times and I would like to take advantage of these benefits now. Since the ovirt engine is now 'recommending' the use of sharding for disk store volumes, this leads me to believe that it is trusted by the oVirt crew. Does this seem accurate?

Info about procedure to shutdown hosted engine VM
by Gianluca Cecchi 12 Sep '18

12 Sep '18

Hello, I'm writing a workflow regarding operations to do in case of planned maintenance where one has to stop all hypervisors and so also hosted engine vm. At the moment I have imagined: - shutdown all VMs but Hosted Engine - put into maintenance and then shutdown all the hosts where Engine is not running, one by one - put environment in global maintenance Now the next step would be to shutdown Hosted Engine VM. As my workflow is for users not necessarily expert with Linux I was thinking what would be an alternate method in respect of direct connect via ssh as root user and run "shutdown -h now" on engine Is there anything I can do from gui of web admin portal or cockpit of the host where it is running? Can I for example select to shutdown engine vm from web admin UI with a certain delay in time so that I disconnect and wait? Or anything I can do from cockpit of the host? Of course I'm searching for a supported flow. Thanks in advance, Gianluca
