With this updated parsing algorithm, meta attributes specified after the meta keyword when it follows the clone keyword are assigned to the clone. In the pcs resource create command, however, the meta attributes specified after the meta keyword when it followed the clone keyword were assigned to the resource rather than to the clone. Previously, the meta keyword was ignored in the pcs resource clone and pcs resource promotable commands. To ensure consistency in the pcs command format, configuring clone meta attributes with the pcs resource clone, pcs resource promotable, and pcs resource create commands without specifying the meta keyword is now deprecated. New pcs parsing requires meta keyword when specifying clone meta attributes Verify the configuration by triggering a kernel panic and check if the vmcore is saved to /dev/vg00/thinvol.Īs a result, with this enhancement, the kdump mechanism now extends capability to save the vmcore dump files on thin provisioned storage volumes. Lvcreate -V 300M -T vg00/thinpool -n thinvolĬonfigure the LVM thin pool threshold to automatically extend the space.Įnable the LVM thin pool monitoring service for the first kernel.Īppend the following lines to the nf file to set the LVM thin volume as the kdump target. Users can now enable and disable wifi and Wireless Wide Area Networks (WWANs) in the nmtui application.īond, bridge, and team connections now use the ignore-carrier=no setting in the section of the /etc/NetworkManager/nf file.Ĭreate a LVM thin pool of 10 MB available space.Ĭreate a LVM thin volume with 300 MB of the file system space. The nm-cloud-setup utility now supports Instance Metadata Service Version 2 (IDMSv2) on Amazon EC2. NetworkManager sets VLAN filtering options by using the kernel’s netlink interface instead of the sysfs file system. To prevent unexpected behaviors in case of multi-connect profiles, NetworkManager now tracks the number of auto-connect retries left for each device and connection instead of only per connection. NetworkManager no longer uses tentative IPv6 addresses to resolve the system hostname from DNS. NetworkManager now adds a version-id argument to Update2() D-Bus calls to prevent concurrent profile modifications. Note that this can add a delay when NetworkManager starts. To avoid race conditions with other depending services, NetworkManager now acquires the D-Bus name only after populating the D-Bus tree. ![]() ![]() NetworkManager now applies DNS options from the section in the /etc/NetworkManager/nf file. When you set a hostname that contains a non-public top-level domain (TLD), NetworkManager now uses this TLD as DNS search domain instead of the full hostname. If external applications or scripts rely on the file names, do not enable this parameter. You can now set a DHCPv6 prefix delegation hint in the ipv6.dhcp-pd-hint connection property.Įnabling the new rename parameter in the section of the /etc/NetworkManager/nf file causes NetworkManager to rename a connection profile in /etc/NetworkManager/system-connections/ if you change a profile name ( connection.id). The arp_missed_max, lacp_active, and ns_ip6_target properties have been added to bond connection profiles. Link-related properties have been added to NetworkManager.If you are modifying an existing connection profile saved in ifcfg-rh format, please migrate the connection to keyfile using 'nmcli connection migrate ' or via the Update2() D-Bus API and try again.Īs a result of these enhancements, NetworkManager now notifies users if they still use or modify connection profiles in the deprecated ifcfg format.įor further details about migrating profiles from ifcfg to keyfile format, see Migrating NetworkManager profiles from ifcfg to keyfile format. The nmcli utility reports the following error if you try to modify a property that is not supported in ifcfg format:Įrror: Failed to modify connection '': failed to update connection: The ifcfg-rh plugin doesn't support setting ''. ![]() Warning: the ifcfg-rh plugin is deprecated, please migrate connections to the keyfile format using "nmcli connection migrate" NetworkManager logs the following warning to the systemd journal if it processes a connection profile in ifcfg format in the /etc/sysconfig/network-scripts/ directory: Dynamic programming languages, web and database serversġ1.14.
