gluster shards not healing
by Jayme 14 Jan '20

14 Jan '20

I have a 3-way replica HCI setup. I recently placed one host in maintenance to perform work on it. When I re-activated it I've noticed that many of my gluster volumes are not completing the heal process. heal info shows shard files in heal pending. I looked up the files and it appears that they exist on the other two hosts (the ones that remained active) but do not exist on the host that was in maintenance. I tried to run a manual heal on one of the volumes and then a full heal as well but there are still unhealed shards. The shard files also still do not exist on the maintenance host. Here is an example from one of my volumes: # gluster volume heal prod_a info Brick gluster0:/gluster_bricks/prod_a/prod_a Status: Connected Number of entries: 0 Brick gluster1:/gluster_bricks/prod_a/prod_a /.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177 /.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.178 Status: Connected Number of entries: 2 Brick gluster2:/gluster_bricks/prod_a/prod_a /.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177 /.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.178 Status: Connected Number of entries: 2 host0: # ls -al /gluster_bricks/prod_a/prod_a/.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177 ls: cannot access /gluster_bricks/prod_a/prod_a/.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177: No such file or directory host1: # ls -al /gluster_bricks/prod_a/prod_a/.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177 -rw-rw----. 2 root root 67108864 Jan 13 16:57 /gluster_bricks/prod_a/prod_a/.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177 host2: # ls -al /gluster_bricks/prod_a/prod_a/.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177 -rw-rw----. 2 root root 67108864 Jan 13 16:57 /gluster_bricks/prod_a/prod_a/.shard/a746f8d2-5044-4d20-b525-24456e6f6f16.177 How can I heal these volumes?

How can I link the cloned disks from a snapshot to the original disks?
by FMGarcia 13 Jan '20

13 Jan '20

Hello, Sorry, I posted in bugzilla, and you advise me than my question isn't error. https://bugzilla.redhat.com/show_bug.cgi?id=1789534 I will attach the same archives and the same text. Description of problem: This problem is bizarre/unusual/convoluted, such that I think that it won't affect to anybody. But the system allows it. In a backup from snapshot with several disks, we can know the original disks from each disk through their names and their sizes. But, and if several disks had the same name and same size? How could we do it without inspect the content of each disk? With the java Sdk, the order of the discs from the original machine to the cloned machine changes, making this path not possible either. In attached files, I show the disks[with different name and order of java Sdk] of the original vm[vm1] and the cloned vm[vm1Clone]. And others[vm2] and [vm2Clone] with the same process, but all disks have the same name. The disks have two sizes: 1Gb and 2Gb. Steps to Reproduce: 1. Create a vm, and attach several disks with same name and same size. 2. Create a backup from snapshot. 3. Now, try to differentiate the disks cloned from original, without looking at their contents. Actual results: I think that it is impossible without I look at their contents. Expected results: Knowing which disk of the cloned machine links to which disk of the original machine. Additional info: If you need more info, request me it Vm.log -> Vm original with different disk name VmClone.log -> Vm clone with different disk name Vm2.log -> Vm original with same disk name Vm2Clone.log -> Cloned vm with same disk name Thanks for your time, Fran

Re: Please Help, Ovirt Node Hosted Engine Deployment Problems 4.3.2
by William Smyth 13 Jan '20

13 Jan '20

I'm running into the exact same issue as described in this thread. The HostedEngine VM (HE) loses connectivity during the deployment while on the NAT'd network and the deployment fails. My HE VM is never migrated to shared storage because that part of the process hasn't been reached, nor have I been asked for the shared storage details, which are simple NFS shares. I've tried the deployment from the CLI and through Cockpit, both times using the Ansible deployment, and both times reaching the same conclusion. I did manage to connect to the Centos 7 host that is running the HE guest with virt-manager and moved the NIC to the 'ovirtmgmt' vswitch using macvtap, which allowed me to access HE from the outside world. One of the big issues though is that the HE isn't on shared storage and I'm not sure how to move it there. I'm running 2 Centos 7 hosts with different CPU makes, AMD and Intel. So i have two separate single-host clusters but I'm trying to at least have the HA setup for the HE, which I think is still possible. I know that I won't be able to do a live migration, but that's not a big deal. I'm afraid my failed deployment of HE is preventing this and I'm at an impasse. I don't want to give up on oVirt but it's becoming difficult to get my lab environment operational and I'm wasting a lot of time troubleshooting. Any help or suggestions would be greatly appreciated.

Hello everyone, I can speak only for myself but I find mailing lists so 1990. Could we migrate this list to something (user friendly) Jira like? I have to admit it's rather difficult to search an read the archive for old issues in the e-mail format. Kind regards Skrzetuski

Setting up cockpit?
by m.skrzetuski＠gmail.com 13 Jan '20

13 Jan '20

Hello everyone, I'd like to get cockpit to work because currently when I click "Host Console" on a host I just get "connection refused". I checked and after the engine installation the cockpit service was not running. When I start it, it runs and answers on port 9090, however the SSL certificate is broken. - How do I auto enable cockpit on installation? - How do I supply my own SSL certification to cockpit? Kind regards Skrzetuski

Re: Unstable VM network connectivity after upgrade 4.2.8 to 4.3.7

Can you check for any differences betwewn the newly created VM and the old one. Set an alias as follows: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Then: virsh dumpxml oldVM virsh dumpxml newVM Maybe somethhing can give a clue what is going on.

Maybe it's related to the CentOS 5.2 e1000 kernel module . Can you install another CentOS 5.2 and verify that the issue exists? Any chance to upgrade the VM to 5.11 or just update the kernel so it is at least 2.6.25 , so you can try the virtio NIC ?

I guess I didn't clarify myself. I asked if you can shutdown the VM and then set only this VM's 'Custom compatibility mode' to 4.2 and power up to test. Yet, if the cluster was at 4.2 when you imported , then I am afraid that the 'Custom Compatibility mode' won't make a difference. I'd recommend you to open a bug on bugzilla.redhat.com and share the link with the mailing list. Many of the dev take a look here.

Low disk space on Storage
by suporte＠logicworks.pt 12 Jan '20

12 Jan '20

Hi, I'm running ovirt Version:4.3.4.3-1.el7 My filesystem disk has 30 GB free space. Cannot start a VM due to an I/O error storage. When tryng to move the disk to another storage domain get this error: Error while executing action: Cannot move Virtual Disk. Low disk space on Storage Domain DATA4. The sum of pre-allocated disk is the total of the storage domain disk. Any idea what can I do to move a disk to other storage domain? Many thanks -- Jose Ferradeira http://www.logicworks.pt
