Using this forces the disk format for -a options which follow on the command line. By default, the kernel is not able to determine the non-volatile storage area unless UEFI is used.

Augeas (software)

Using --format with no argument switches back to auto-detection for subsequent -a options. To disable THP via sysfs and confirm it is disabled, do the following as root: This is an alternative to the -a option: To switch to persistent device names on a system that has already been installed, start the YaST2 partitioner.

Beside the fact that the BIOS has to export the relevant information, the kernel needs the following boot parameter: This issue is solved for Dell hardware, which has the corresponding BIOS support, by renaming onboard network interfaces to em[], which maps to Embedded NIC[] as labeled on server chassis.

To switch to persistent device names on a system that has already been installed, start the YaST2 partitioner. A recent example of this is the Postfix main. Some database systems and enterprise business applications expect processes and tasks run under a specific user name not root.

This path will be used as either an explicit set of accepted certificates or an OpenSSL-verify path directory of well-formed filename certificates.

Puppet – Augeas – Edit System configuration files

There are three alternatives to resolve this issue: You may see strange or inconsistent results if running concurrently with other changes, but with this option you won't risk disk corruption. If the feature is enabled, an interface by name "memory. Cgroup Swap Control Right now only the memory usage with respect to a cgroup can be controlled.

They could also try to exploit the Linux kernel or qemu provided by the libguestfs appliance. There could be MBs worth of data in the backing store. These added disks are not displayed in the partitioner automatically. It is more equivalent to using the readdir 3 call on a local filesystem. These did not work properly, are deprecated, and should not be used in new code.

The virtual machine must be shut down before you use this command, and disk images must not be edited concurrently. If the driver is unloaded prior to the operation and then loaded again afterwards, adapter initialization may fail.

If the --ro option is also used, then any libvirt domain can be used. The reason is that the call enters the FUSE main loop and processes kernel requests, turning them into libguestfs calls.

Bidirectional transformation

If you want to rescue a broken virtual machine image, you should look at the virt-rescue 1 command.Homepage: agronumericus.com Mailing List: agronumericus.com VCS: agronumericus.com Lenses. Already Supported. Port Manteaux churns out silly new words when you feed it an idea or two. Enter a word (or two) above and you'll get back a bunch of portmanteaux created by jamming together words that are conceptually related to your inputs.

For example, enter "giraffe" and you'll get. NAME; SYNOPSIS; WARNING; DESCRIPTION; EXAMPLES. As an interactive shell; From shell scripts; On one command line; Mount disks automatically; As a script interpreter.

[Puppet Users] Augeas lens dependency on valid config file parsing

A change in one config file can affect Augeas which Lenses can be written either to match a file format very specifically (as in this case) or quite loosely. There are pros and cons to each.

Clearly writing a fairly loose definition for the file which accepts something like [a-z_]+ for the name of a setting is useful when. name; synopsis; description; api overview. handles; disk images; mounting; filesystem access and modification; partitioning; lvm2; downloading; uploading; copying.
