Boot time creation of mapped devices
|
||||
===================================
|
||||
|
||||
It is possible to configure a device mapper device to act as the root
|
||||
device for your system in two ways.
|
||||
|
||||
The first is to build an initial ramdisk which boots to a minimal
|
||||
userspace which configures the device, then pivot_root(8) in to it.
|
||||
|
||||
For simple device mapper configurations, it is possible to boot directly
|
||||
using the following kernel command line:
|
||||
|
||||
dm="<name> <uuid> <ro>,table line 1,...,table line n"
|
||||
|
||||
name = the name to associate with the device
|
||||
after boot, udev, if used, will use that name to label
|
||||
the device node.
|
||||
uuid = may be 'none' or the UUID desired for the device.
|
||||
ro = may be "ro" or "rw". If "ro", the device and device table will be
|
||||
marked read-only.
|
||||
|
||||
Each table line may be as normal when using the dmsetup tool except for
|
||||
two variations:
|
||||
1. Any use of commas will be interpreted as a newline
|
||||
2. Quotation marks cannot be escaped and cannot be used without
|
||||
terminating the dm= argument.
|
||||
|
||||
Unless renamed by udev, the device node created will be dm-0 as the
|
||||
first minor number for the device-mapper is used during early creation.
|
||||
|
||||
Example
|
||||
=======
|
||||
|
||||
- Booting to a linear array made up of user-mode linux block devices:
|
||||
|
||||
dm="lroot none 0, 0 4096 linear 98:16 0, 4096 4096 linear 98:32 0" \
|
||||
root=/dev/dm-0
|
||||
|
||||
Will boot to a rw dm-linear target of 8192 sectors split across two
|
||||
block devices identified by their major:minor numbers. After boot, udev
|
||||
will rename this target to /dev/mapper/lroot (depending on the rules).
|
||||
No uuid was assigned.

extra_free_kbytes

This parameter tells the VM to keep extra free memory between the threshold

where background reclaim (kswapd) kicks in, and the threshold where direct

reclaim (by allocating processes) kicks in.
|

This is useful for workloads that require low latency memory allocations

realtime application that receives and transmits network traffic
|

(causing in-kernel memory allocations) with a maximum total message burst

size of 200MB may need 200MB of extra free memory to avoid direct reclaim

related latencies.

Hash blocks are still verified each time they are read from the
