[OmniOS-discuss] Centos 7 LX brand -- lvmetad filling the system log -- instructions to disable it

[Geoff Nordli]

I am doing some testing on r151020 with the LX Brand.

I downloaded the latest Centos7 image.

https://docs.joyent.com/public-cloud/instances/infrastructure/images/centos#centos-7-20161213

I logged in and I was able to do a yum update on the image so everything 
looks good.

One thing I noticed is the /var/log/messages is filling up with messages 
like:

Apr 14 23:30:00 test2 lvmetad[7365]: Failed to accept connection errno 11.
Apr 14 23:30:00 test2 lvmetad[7365]: Failed to accept connection errno 11.
Apr 14 23:30:00 test2 lvmetad[7365]: Failed to accept connection errno 11.
Apr 14 23:30:00 test2 lvmetad[7365]: Failed to accept connection errno 11.
Apr 14 23:30:00 test2 lvmetad[7365]: Failed to accept connection errno 11.
Apr 14 23:30:00 test2 lvmetad: select error: Invalid argument
Apr 14 23:30:00 test2 lvmetad: select error: Invalid argument
Apr 14 23:30:00 test2 lvmetad: select error: Invalid argument

Not really sure why that daemon is required, since LX doesn't seem use 
LVM to manage any disks.

To disable it I did the following:

 1. Disable and stop the *lvm2-lvmetad service* by running the following
    commands:

    systemctl disable lvm2-lvmetad
    systemctl stop lvm2-lvmetad

 2. Disable and stop the *lvm2-lvmetad.socket* service by running the
    following commands:

    systemctl disable lvm2-lvmetad.socket
    systemctl stop lvm2-lvmetad.socket

 3. Disable *lvmetad* in the LVM config file by running the following
    command:

    edit /etc/lvm/lvm.conf to include use_lvmetad = 0


I am quite stoked about the LX brand!!

thanks,

Geoff
