Recover accidentally deleted gluster node having bricks ( Engine, Data and Vmstore)
by Abhishek Sahni 27 Nov '18

27 Nov '18

Hello Team, We are running a setup of 3-way replica HC gluster setup configured during the initial deployment from the cockpit console using ansible. NODE1 - /dev/sda (OS) - /dev/sdb ( Gluster Bricks ) * /gluster_bricks/engine/engine/ * /gluster_bricks/data/data/ * /gluster_bricks/vmstore/vmstore/ NODE2 and NODE3 with a similar setup. There is a mishap that /dev/sdb on NODE2 totally got crashed and now there is nothing inside. However, I have created similar directories after mounting it back i.e., * /gluster_bricks/engine/engine/ * /gluster_bricks/data/data/ * /gluster_bricks/vmstore/vmstore/ but it is not yet recovered. ===================================================== [root@node2 ~]# gluster volume status Status of volume: data Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick *.*.*.1:/gluster_bricks/data/data 49152 0 Y 11111 Brick *.*.*.2:/gluster_bricks/data/data N/A N/A N N/A Brick *.*.*.3:/gluster_bricks/data/data 49152 0 Y 4303 Self-heal Daemon on localhost N/A N/A Y 23976 Self-heal Daemon on *.*.*.1 N/A N/A Y 27838 Self-heal Daemon on *.*.*.3 N/A N/A Y 27424 Task Status of Volume data ------------------------------------------------------------------------------ There are no active volume tasks Status of volume: engine Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick *.*.*.1:/gluster_bricks/engine/eng ine 49153 0 Y 11117 Brick *.*.*.2:/gluster_bricks/engine/eng ine N/A N/A N N/A Brick *.*.*.3:/gluster_bricks/engine/eng ine 49153 0 Y 4314 Self-heal Daemon on localhost N/A N/A Y 23976 Self-heal Daemon on *.*.*.3 N/A N/A Y 27424 Self-heal Daemon on *.*.*.1 N/A N/A Y 27838 Task Status of Volume engine ------------------------------------------------------------------------------ There are no active volume tasks Status of volume: vmstore Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick *.*.*.1:/gluster_bricks/vmstore/vm store 49154 0 Y 21603 Brick *.*.*.2:/gluster_bricks/vmstore/vm store N/A N/A N N/A Brick *.*.*.3:/gluster_bricks/vmstore/vm store 49154 0 Y 26845 Self-heal Daemon on localhost N/A N/A Y 23976 Self-heal Daemon on *.*.*.3 N/A N/A Y 27424 Self-heal Daemon on *.*.*.1 N/A N/A Y 27838 Task Status of Volume vmstore ------------------------------------------------------------------------------ There are no active volume tasks ============================================================= Can someone please suggest the steps to recover the setup?

Upgrade 4.0 to 4.1: Global Maintenance Mode not recognized
by gregor 27 Nov '18

27 Nov '18

Hello, I upgraded one host from 4.0 to 4.1 without problems. Now I have a problem with another host, in another network, where the Global Maintenance mode is not recognized by engine-setup. Is there a way to force the setup or set the maintenance mode inside the database? One problem can be that an the host was accidentally upgraded to 4.1 before I upgraded the engine. kind regards gregor

oVirt impersonation and sessions
by Anastasiya Ruzhanskaya 26 Nov '18

26 Nov '18

Hello everyone! I wanted to find out how the impersonation technique used in oVirt works? I know from libvirt developers, that oVirt opens one connection only for multiple clients. How does this work? Also I found out in source code that in ActionParameterBase class the sessionId field is marked transient but, for example, for GWT rpc message, which goes to the server and says what action will be made (shut down, pause vm) this is the only field in all sent information which says what the session is. Where is the session sent instead? There was also a field with session id in https headers, but this was related to cookie so I am not completely sure if this can help to identify the current user.

How to kill hanged task listed in engine but not in vdsm-client?
by Stefano Stagnaro 26 Nov '18

26 Nov '18

Hello, I'm struggling with an hanged task. I can see it from RestAPI (and UI) as: <job href="/ovirt-engine/api/jobs/9326a95e-4686-4205-bbac-b552beae4d29" id="9326a95e-4686-4205-bbac-b552beae4d29"> <actions> <link href="/ovirt-engine/api/jobs/9326a95e-4686-4205-bbac-b552beae4d29/clear" rel="clear"/> <link href="/ovirt-engine/api/jobs/9326a95e-4686-4205-bbac-b552beae4d29/end" rel="end"/> </actions> <description>Adding Disk</description> <link href="/ovirt-engine/api/jobs/9326a95e-4686-4205-bbac-b552beae4d29/steps" rel="steps"/> <auto_cleared>true</auto_cleared> <external>false</external> <last_updated>2018-11-23T18:40:59.466+01:00</last_updated> <start_time>2018-11-23T18:06:18.512+01:00</start_time> <status>started</status> <owner href="/ovirt-engine/api/users/6f4573b6-0cf1-4cbb-ac03-bf8e126b394c" id="6f4573b6-0cf1-4cbb-ac03-bf8e126b394c"/> </job> The job is hanged since user has killed fallocate process on the host. However, I can't kill task from the hosts itself since vdsm-client returns zero task on any host: # vdsm-client Host getAllTasksInfo {} How can I deal with it? I already tried to restart ovirt-engine.service but task is still there and prevent me to put the involved storage domain into maintenance. I also tried the "clear" method for service "job" via RestAPI but it fails since it's not an external job. Thank you, -- Stefano Stagnaro Prisma Telecom Testing S.r.l.

AffinityGroup API
by p.staniforth＠leedsbeckett.ac.uk 26 Nov '18

26 Nov '18

Hello, When using the API to update an AffinityGroup there is a AffinityGroupVm and AffinityGroupVms so I can add or remove VMs but there is no AffinityGroupHost or AffinityGroupHosts, therefore I can't add or remove hosts. Thanks, Paul S.

IPA Users via AD DC's
by TomK 26 Nov '18

26 Nov '18

Hello, I've configured LDAP via IPA in oVirt 4.X. It works for locally defined users in IPA but not those mapped from the AD DC. So I had two questions: 1) Is there a format of the username and password I need to type in for this to work? Or is retrieving AD DC mapped users not possible with oVirt right now? 2) Can I use two providers in oVirt simultaneously? One IPA and the other AD? -- Cheers, Tom K. ------------------------------------------------------------------------------------- Living on earth is expensive, but it includes a free trip around the sun.

VM has snapshots with disks in illegal status
by Markus Schaufler 26 Nov '18

26 Nov '18

Hi! I've testet a backup solution which turned out to work not as expected. It left some VM's turned off which cannot be restarted. When trying to delete the snapshot(s) of the vms following error message occurs: "Cannot remove Snapshot. The following attached disks are in ILLEGAL status: System, Disk2 - please remove them and try again" Also I cannot detach any disk because of: Cannot remove Snapshot. The following attached disks are in ILLEGAL status: System, SRV_Metrics-Store_Disk1 - please remove them and try again. I already tried via "unlock_entity" script to remove either the snapshots or the disks (after backing them up) and via CLI but without success (same error message). Any idea on that?
