Blktool

blktool - Blockgeräteeinstellungen anzeigen oder ändern

Beschreibung

Tunen der Low-Level-Blockgeräteparameter

blktool wird zum Abfragen und/oder Ändern der Einstellungen eines Blockgeräts verwendet

• Es ähnelt hdparm, ist jedoch ein allgemeineres Tool, da es auf SCSI-, IDE- und SATA-Geräten funktioniert

Warnung

Dieses Programm ist für diejenigen gedacht, die wissen, was sie tun, und es sollte auf eigene Gefahr verwendet werden, da es Ihre Hardware beschädigen könnte

Installation

sudo apt install blktool

blktool [options] device [COMMAND]

device ist der Name des Blockgeräts, das abgefragt oder geändert werden soll

Optionen

Unix	GNU	Parameter	Beschreibung
-f			For a few commands, blktool will flush the buffers of the block device out to disk, before performing the requested command Specify this option, "force", disables any flushing blktool would attempt to do
-t		class	where class is one of 'ide', 'ata', 'scsi', 'i2o', or 'auto' to override the default auto-detection of device class

Befehle

Befehl	Beschreibung
acoustic-mgmt	Query or set underlying device's acoustic level
block-sz	Query or set device block size
bus-id Query device bus id
bus-state	Query or set device bus state (0 off, 1 on, 2 tristate)
class Query the detected (or overridden, via -t) device class Typically this will result in 'ATA' or 'SCSI' for most devices Detection is based on device major; thus your SATA device may ap‐ pear as 'SCSI'
cd-speed	Set CD-ROM device speed (in Kbytes/sec)
defect-mgmt	Toggle underlying device's defect management (obsolete)
dev-keep-settings	Toggle underlying device's revert-to-defaults-on-reset feature
dev-read-ahead	Toggle underlying device's read-ahead feature
dma Toggle DMA data transfer Omitting the on/off argument will print the current state
geometry	Query device geometry (cylinders / heads / sectors / und weitere)
i2o-rcache	Query or set an I2O block device's read cache
i2o-wcache	Query or set an I2O block device's write cache
id Query IDENTIFY [PACKET] DEVICE data
keep-settings	Keep settings across device resets Omitting the on/off argument will print the current state
media Lock in (or unlock) a removable device
multiple-count	Set multiple count for use in READ/WRITE MULTIPLE commands
no-write-err	Toggle ignore-write-errors flag Omitting the on/off argument will print the current state
pio-data	ATA PIO data transfer via 16-bit or 32-bit I/O Omitting the on/off argument will print the current state
pio-mode	Set underlying ATA device's PIO data transfer mode
pm-mode	Set underlying device's Advanced Power Management mode
queued-depth	Query or set underlying device's queue depth
read-ahead	Query or set block device read-ahead (in units of sectors)
readonly	Toggle block device read-only setting Omitting the on/off argument will print the current state
reread-part	Re-read partition table
reset Execute device reset
sector-sz	Query device sector size
sleep Put device to sleep immediately
standby	Put device in standby mode
unmask-irq	Toggle unmasked irqs Omitting the on/off argument will print the current state
version	Print version number and exit
wcache Toggle underlying device's writeback cache
