[ovirt-users] Two or more mount process running for engine volume

[knarra]

Hi All,

I have hosted engine setup with glusterfs as my storage domain. 
when i move a storage domain to maintenance and activate it again i see 
that there are two glusterfs process running for every storage domain. 
Is this expected behaviour or a bug ?


root 27143  0.0  0.0 451308 40556 ?S/usr/sbin/glusterfs --volfile-server= 
--volfile-server= --volfile-server= 
--volfile-id=/vmstore /rhev/data-center/mnt/glusterSD/:_vmstore
root 28125 27.7  0.0 584512 49824 ?S/usr/sbin/glusterfs --volfile-server= 
--volfile-server= --volfile-server= 
--volfile-id=/vmstore /rhev/data-center/mnt/glusterSD/:_vmstore


Can some please help me in understanding this?

Thanks

Re: [ovirt-users] hosted-engine setup Gluster fails to execute

[Langley, Robert]

Outstanding! Thank you Sahina! Your assistance is much appreciated.
When I saw your email it reminded me that the versions were different and I was 
having an issue with reaching the internet from the engine storage servers. A 
DNS issue between my private DNS server and my organization's DNS server. I 
figured out a workaround and found that I had to install the ovirt release36 
rpm repository also. Since my host server had 3.7 (since it had the oVirt 
release36 rpm repository) and my engine storage would only upgrade to the 
latest 3.6 GlusterFS version. All are now at Glusterfs 3.7.11 and working. I 
got past the storage configuration.

Command that failed to execute from your hosted-engine node - "gluster volume 
info engine-vol --remote-host gsave0.engine.local"

Can you check the glusterfs versions on the hosted-engine node and 
gsave0.engine.local node - are they the same?

Hi Sahina,

Thank you for your response. Let me know if you'll need any of the log before

why, after choosing to use GlusterFS, there is still reference to NFS (nfs.py)? 
I do believe NFS is disabled in my Gluster config for the engine cluster.

It's just an implementation detail of hosted-engine-setup:
iSCSI an FC commands are define in blockd.py while commands for file based 
storage domains (NFS and gluster) are defined in nfs.py.

I just do a full clone of the whole VM and the clone is running fine and 
have the last data on all disks.

Betreff: [ovirt-users] Snapshot is "Locked" - Can't do anything with the VM

Hi oVirt List

We have the problem, that two of our VM's have "Locked" snapshots and we
can't go forward. From 10 VM's which we move from one store to another,
we have problems with 5 of them to delete the snapshots. But with a lot
of luck, the snapshot was always on the dedicated Swap-Disk, so we just
have to remove the whole disk and create it again as new.

Because we replace all the filers, we have to move the VM's arround. The
move itself runns fine, but deleting the snapshots doesn't work sometimes.

I found a lot about our problem, but I can't find any solution, which
works an our environment.

Our setup:
- 3 Solaris filer with NFS exports for the hosts for the vm-images
- 8 hosts (oVirt 3.6 / Centos 7.2.1511)
- The engine host is located outside of the DC, connected via VPN

At the moment, one of the "problem-VM" is productive, the other should
become productive in the next days, so we focus us to the 2nd VM,
because we can play arround with them. The other one is startet up, but
i have no idea, what happens, when i shut them down...

This is the status today of VM, which is not productive at the moment:
- VM Status: Down
- Snapshots OK: 2
- Snapshots Locked: 1
- In the snapshot tab, everything is grayed out (Create, Preview,
Commit, Undo etc.)
- No active tasks are displayed

Error message when i try to start the VM:
"Cannot run VM. The VM is performing an operation on a Snapshot. Please
wait for the operation to finish, and try again."

Something about the history of this VM:
1. We start the disk move from filer1 to filer3, totaly 4 drives,
everything was fine
2. Deleting snapshots, i think one or two runns fine
3. Deleting the 2nd or 3rd snapshot runs two days without an end
4. Rebooting the Engine
5. No task anymore in the Tasks list
6. The status of the snapshot is "Locked", die Disk of this snapshot
becoms "Illegal" and red
7. Shutdown the VM -  no luck, i can't start it again --> "Cannot run
VM. The VM is performing an operation on a Snapshot. Please wait for the
operation to finish, and try again."
8. We move the disk back from filer3 to the filer1
9. The status of the snapshot is "Locked", die Disk of this snapshot
becoms "OK" and green
...but i can't delete the snapshot or starting the VM :(

Today, i copy the image files to a dedicated KVM host, which is not
involved in the oVirt environment and i merge the image manualy together:
qemu-img convert -p -f qcow2 804ffcc3-446f-4c56-ba99-ab90c7951a6f -O raw
Merged1

I mount the image and everything fine, all the changes from the last two
days are now in a base image. I try to remove the whole disk in oVirt,
but i still got the error message, that i have to wait. So for me, the
next step is to create a new VM and migrate everything manualy, this
will work, but can't be the solution for the other VM, which is
productive and it have the same problem.

Re: [ovirt-users] Snapshot is "Locked" - Can't do anything with the VM

[Ivo Rütsche]

Salü Markus

Yes, i saw also some postings arround, but no solution and all of them 
was a bit different than our situation.


The VM is always responsible, as long as we don't shut it down.

I need to have a focus on it, but I think when I do it like this:

delete all snapshots
moving 1st Disk -> delete snapshot
moving 2nd Disk -> delete snapshot
moving 3rd Disk -> delete snapshot

I don't get in troubles, than I move all the disk and then I remove all 
the snapshots.


Maybe I can deliver more logs to help to solve the problem?

Re: [ovirt-users] Snapshot is "Locked" - Can't do anything with the VM

[Markus Stockhausen]

Hi,

we've seen a lot of trouble when deleting snapshots of multidisk VMs.
Especially endless running snapshot deletions is one of our culprits.

Betreff: [ovirt-users] Snapshot is "Locked" - Can't do anything with the VM

Hi oVirt List

We have the problem, that two of our VM's have "Locked" snapshots and we
can't go forward. From 10 VM's which we move from one store to another,
we have problems with 5 of them to delete the snapshots. But with a lot
of luck, the snapshot was always on the dedicated Swap-Disk, so we just
have to remove the whole disk and create it again as new.

Because we replace all the filers, we have to move the VM's arround. The
move itself runns fine, but deleting the snapshots doesn't work sometimes.

I found a lot about our problem, but I can't find any solution, which
works an our environment.

Our setup:
- 3 Solaris filer with NFS exports for the hosts for the vm-images
- 8 hosts (oVirt 3.6 / Centos 7.2.1511)
- The engine host is located outside of the DC, connected via VPN

At the moment, one of the "problem-VM" is productive, the other should
become productive in the next days, so we focus us to the 2nd VM,
because we can play arround with them. The other one is startet up, but
i have no idea, what happens, when i shut them down...

This is the status today of VM, which is not productive at the moment:
- VM Status: Down
- Snapshots OK: 2
- Snapshots Locked: 1
- In the snapshot tab, everything is grayed out (Create, Preview,
Commit, Undo etc.)
- No active tasks are displayed

Error message when i try to start the VM:
"Cannot run VM. The VM is performing an operation on a Snapshot. Please
wait for the operation to finish, and try again."

Something about the history of this VM:
1. We start the disk move from filer1 to filer3, totaly 4 drives,
everything was fine
2. Deleting snapshots, i think one or two runns fine
3. Deleting the 2nd or 3rd snapshot runs two days without an end
4. Rebooting the Engine
5. No task anymore in the Tasks list
6. The status of the snapshot is "Locked", die Disk of this snapshot
becoms "Illegal" and red
7. Shutdown the VM -  no luck, i can't start it again --> "Cannot run
VM. The VM is performing an operation on a Snapshot. Please wait for the
operation to finish, and try again."
8. We move the disk back from filer3 to the filer1
9. The status of the snapshot is "Locked", die Disk of this snapshot
becoms "OK" and green
...but i can't delete the snapshot or starting the VM :(

Today, i copy the image files to a dedicated KVM host, which is not
involved in the oVirt environment and i merge the image manualy together:
qemu-img convert -p -f qcow2 804ffcc3-446f-4c56-ba99-ab90c7951a6f -O raw
Merged1

I mount the image and everything fine, all the changes from the last two
days are now in a base image. I try to remove the whole disk in oVirt,
but i still got the error message, that i have to wait. So for me, the
next step is to create a new VM and migrate everything manualy, this
will work, but can't be the solution for the other VM, which is
productive and it have the same problem.

Note in 4.0 we have split groups and users, and you have to select which type 
you want to search for. This is to reduce the number of queries to the LDAP 
server.

Sure, if you type some search term into UI users/permissions dialog it

In that case, the dn would be different, is it possible to specify multiple dn

Re: [ovirt-users] ovirt-vmconsole serial

[Gianluca Cecchi]

Hello,
I attach to this thread to detail how I was able to have serial console
working both on CentOS 6.7 and CentOS 7.2 VMs on 3.6.5

- CentOS 6.7
Basically what described in general here (but using ttyS0 instead ttyS1):
http://www.cyberciti.biz/faq/centos-rhel-6-install-serial-console/

So in /boot/grub/grub.conf

a) right before the "hiddenmenu" line:

serial --unit=*0 *--speed=19200 --word=8 --parity=no --stop=1
terminal --timeout=5 serial console

b) At the end of kernel line added:
console=tty0 console=ttyS*0*,19200n8

Added at the end of /etc/securetty the line
ttyS0

Only difference is that as I used ttyS0, the upstart configuration was not
needed: the system after reboot was already listening on ttyS0
Creating upstart config file generated 2 processes listening on ttyS0


- CentOS 7.2
created VM with virtio console enabled in options and basically following
what described here
https://www.youtube.com/watch?v=Sx2HRwFqG7o

from default configuration I got after install:

Add in /etc/default/grub "console=ttyS0" in GRUB_CMDLINE_LINUX so that it
is now:
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet
console=ttyS0"

grub2-mkconfig -o /boot/grub2/grub.cfg

reboot the VM

You can specify custom base DN, which overrides the one which is
automatically resolved if
you add following lines into /etc/ovirt-engine/aaa/your_profile.properties:

 sequence-init.init.100-my-basedn-init-vars = my-basedn-init
 sequence.my-basedn-init.010.description = set custom baseDN
 sequence.my-basedn-init.010.type = var-set
 sequence.my-basedn-init.010.var-set.variable = simple_baseDN
 sequence.my-basedn-init.010.var-set.value = dc=your,dc=different,dc=dn


Thank you, now I see the correct namespace shown, but still no way to login 
with any user...Any idea ?



Hard to say without logs, can you please share log output of 
ovirt-engine-extensions-tool?

Please run it with:
 ovirt-engine-extensions-tool --log-level=FINEST --log-file=output.log 
aaa login-user  --profile=xxx --user-name=xxx

How can I proceed? Could I just run this script

You could do service ovirt-engine restart and remove the host from the 
UI. Redeploying the second time should work fine.

Thank you. This is what I've done and succeeded:
1. Set host03 to maintenance.
2. Remove host03.
3. redeploy host03 with "hosted-engine --deploy" but failed with "[ 
ERROR ] Failed to execute stage 'Programs detection': Hosted Engine HA 
services are already running on this system. Hosted Engine cannot be 
deployed on a host already running those services."
4. Run the script from 
https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-from-failed-install

5. Install ovirt-hosted-engine-setup again.
6. Redeploy again.

Thanks for your report Gianluca,
adding virtio-rng or adding haveged daemon to the appliance is indeed
a good idea: could you please fill an RFE on bugzilla for that?

It's just an implementation detail of hosted-engine-setup:
iSCSI an FC commands are define in blockd.py while commands for file
based storage domains (NFS and gluster) are defined in nfs.py.

This is something that happens after the engine called setupNetworks
and, due to some side effects, it loose the communication with the
host.

The issue is tracked here:
https://bugzilla.redhat.com/1323465
we are going to solve for 3.6.6

As Knarra said, you can simply try redeploying it and it could work:
this issue is not fully systematic.
In order to retry you need to remove your host from the engine and in
order to do that you probably need to move it to maintenance mode.

Re: [ovirt-users] Additional hosted-engine host deployment failed due to message timeout

Hi,

How can I proceed? Could I just run this script

You could do service ovirt-engine restart and remove the host from the 
UI. Redeploying the second time should work fine.

Re: [ovirt-users] hosted-engine setup Gluster fails to execute

[Sahina Bose]

Command that failed to execute from your hosted-engine node - "gluster 
volume info engine-vol --remote-host gsave0.engine.local"


Can you check the glusterfs versions on the hosted-engine node and 
gsave0.engine.local node - are they the same?

Hi Sahina,

Thank you for your response. Let me know if you’ll need any of the log

I was wondering why, after choosing to use GlusterFS, there is still

What exactly is gone? Only httpd conf?

You can try something like this:

engine-setup --otopi-environment='OVESETUP_APACHE/configured=bool:False'

Or, try to setup another engine on a different machine and compare
/etc/httpd/conf.d between them.
