Hi,

Would pulling the latest version of netdata into each host break anything?
ie running from the cli: bash <(curl -Ss https://my-netdata.io/kickstart.sh)

@olivierlambert The servers (2) I am seeing the memory leaks are used exclusively for network intensive applications. they route and tunnel many (100+) tunnels.

Other systems I have with similar host configuration are not seeing any increased domain memory usage.

We also have 10GbE Intel interfaces on the affected servers, not using iscsi yet on these servers.

So I think the comon factors right now would be the sas megaraid and 10GbE Intel nics?

@eperez539 good luck

Good job guys!

So, I checked the other hosts in my environment that run the same types of VMs and also have the same version of xcp-ng.

Hosts that are not seeing this memory leak have BCM5720 1GbE interfaces. They are not as heavily used so I'm not sure if the leak only occurs if usage is very high or using a specific feature/ function in that driver.

@olivierlambert I don't have a ticket because we don't have paid support for xcp-ng

@stormi

our environment also seeing the leak in xcp-ng 8.1 hosts. At first I doubled the amount of memory allocated to the control domain from 4G to 8G and now 30 something days later it ran out of ram again... this is the 3rd time the hosts (4) run of memory. This is really causing us issues.

Hi, I was just reading the changelog for the latest July 31st XOA release and saw that it was now possible to backup to AWS S3, will Azure eventually be supported as well?

@eperez539 good luck

@eperez539

You need to add the following 2 lines to /usr/lib/cloud-init/ds-identify at or around line 245 if your file is different than mine.

         LABEL_FATBOOT=*) label="${line#LABEL_FATBOOT=}";
                           labels="${labels}${line#LABEL_FATBOOT=}${delim}";;

The file diff /usr/lib/cloud-init/ds-identify.ORIGINAL is just a backup of the original file. You should do the same in case you need to roll back changes one day.

Here's the end result in my file (see line 245 where I added the above):

    236     for line in "$@"; do
    237         case "${line}" in
    238             DEVNAME=*)
    239                 [ -n "$dev" -a "$ftype" = "iso9660" ] &&
    240                     isodevs="${isodevs},${dev}=$label"
    241                 ftype=""; dev=""; label="";
    242                 dev=${line#DEVNAME=};;
    243             LABEL=*) label="${line#LABEL=}";
    244                      labels="${labels}${line#LABEL=}${delim}";;
    245             LABEL_FATBOOT=*) label="${line#LABEL_FATBOOT=}";
    246                              labels="${labels}${line#LABEL_FATBOOT=}${delim}";;
    247             TYPE=*) ftype=${line#TYPE=};;
    248             UUID=*) uuids="${uuids}${line#UUID=}$delim";;
    249         esac
    250     done

I got it working by applying the diff you posted above. I edited the ds-identity file and added the fatboot label. I then added the datasource entries to cloud.cfg.

I converted to a template and 1st bootup it updated automaticaly and ran everything I had already setup in the cloud.cfg.

I would say that the blog post from December 2015 or the wiki needs to be updated with that new information. Also worth mentioning is that unless a network configuration is specified in the cloud.cfg file you need to add this snippet at the bottom so that any future customization of the network interfaces doesn't get wiped up by cloud-init:

network:
  config: disabled
