[ovirt-users] sanlock issues after 4.3 to 4.4 migration

[Strahil Nikolov via Users]

Hello All,

I was trying to upgrade my single node setup (Actually it used to be 2+1 
arbiter, but one of the data nodes died) from 4.3.10 to 4.4.? 

The deployment failed on 'hosted-engine --reinitialize-lockspace --force' and 
it seems that sanlock fails to obtain a lock:

# hosted-engine --reinitialize-lockspace --force

Could it be related to the sector size of the Gluster's Brick?

# smartctl -a /dev/sdb | grep  'Sector Sizes'
Sector Sizes: 512 bytes logical, 4096 bytes physical


Any hint will be helpful

[ovirt-users] Sanlock issues after upgrading to 3.4

[Jairo Rizzo]

Hello,

I have a small 2-node cluster setup running Glusterfs in replication mode :

CentOS v6.5
kernel-2.6.32-431.17.1.el6.x86_64
vdsm-4.14.6-0.el6.x86_64
ovirt-engine-3.4.0-1.el6.noarch  (on 1 node)

Basically I was running ovirt-engine v 3.3 for months fine and then
upgraded to latest version of 3.3.X two days ago and could not join the
nodes to the cluster due to a version mismatch,basically this:
https://www.mail-archive.com/users@ovirt.org/msg17241.html  . After trying
to correct this problem I ended up upgrading to 3.4 which created a new and
challenng problem for me. Every couple of hours I get error messages like
this:

This makes one of the nodes not be able to see the storage and all its VMs
will go into pause mode/stop. Wondering if you could provide some advice.
Thank you

yes, look up faqemu for details on setting up a virtual host (though
the VM won't really run), or enable nested virtualization on fedora 17.

history and reports are still not packaged in rpm form in ovirt - still 
work in progress. you can install on your own if you want to tackle 
(yaniv - any link to how to setup history/reports from sources?)


ovirt supports external directories.
easiest to add users would be to install freeipa and add it via manage 
domains utility

you should be able to setup an "all in one" deployment from ovirt
rpms using fedora 17, ovirt 3.1 with the allinone plugin installed
on a single machine with say, 8GB of RAM.

Shouldn't the following issue have fixed this already?

[Users] sanlock issues

[Jacob Wyatt]

Solved with a hack.

oVirt Node Hypervisor release 2.5.0 (2.0.fc17)

Couldn't start a VM because sanlock wasn't running.
Sanlock wasn't running because wdmd wasn't running.
wdmd was running because softdog kernel module wasn't loaded.

As I didn't know of another way of making the change persistent I edited 
/config/usr/sbin/ifup and added "/sbin/modprobe softdog" to the top of the 
script.

I really think it would be a good idea for the oVirt Node team to add in some 
persistent script files that are run at various points in the boot process so 
that people like me can add in hacks where needed to make it work.

# grep -v ^#  /etc/libvirt/qemu-sanlock.conf
auto_disk_leases=0
require_lease_for_disks=0

I did try systemd-vdsmd reconfigure.


From: Mark Wu [wu...@linux.vnet.ibm.com]

What does  "grep -v ^#  /etc/libvirt/qemu-sanlock.conf"  say?

Have you tried `/usr/lib/systemd/systemd-vdsmd reconfigure` ?

http://wiki.ovirt.org/wiki/SANLock   Hope it helps for you.



Since LUN's are mapped to all the machines in the cluster, I guess it is not on 
that level, but more on the Logical Volume level, since it is the LV that is 
used by the host.

I would like to get some deeper info about how the the storage architecture is 
implemented, and what the storage strategy is for the future...Someone can 
enlighten me? Show me to some documentation?
