The problem seems linked with a network problem on my clients. The ipxe boot file undionly.kpxe.INTEL was bricking my network adapters. I switched back to undionly.kpxe and everything is back to normal.

Hello,

I’m trying to deploy an image using multicast. All machines boot normaly in fog but when they should launch partclone I have lines starting with “* #!im (xx min)” instead.
I can deploy my image normaly using unicast.

Does anyone know what this message mean?

Thanks

Hello,

In some cases multicast speed could be very poor. Especially when your for server is linked to your switch with a 1Gb/s link and your clients are on 100Mb/s links.

One workaround is to force the --max-bitrate option of udp-sender to a value around “80m” (best compromise in my case). Actually it must be done by editing service/common/lib/MulticastTask.class.php manually
