blkzone - run zone command on a device
blkzone command [options] device
blkzone is used to run zone command on device that support the Zoned
Block Commands (ZBC) or Zoned-device ATA Commands (ZAC). The zones to
operate on can be specified using the offset, count and length
options.
The device argument is the pathname of the block device.
report
The command blkzone report is used to report device zone information.
By default, the command will report all zones from the start of the
block device. Options may be used to modify this behavior, changing
the starting zone or the size of the report, as explained below.
Report output
start Zone start sector
len Zone length in number of sectors
cap Zone capacity in number of sectors
wptr Zone write pointer position
reset Reset write pointer recommended
non-seq Non-sequential write resources active
cond Zone condition
type Zone type
Zone conditions
cl Closed
nw Not write pointer
em Empty
fu Full
oe Explicitly opened
oi Implicitly opened
ol Offline
ro Read only
x? Reserved conditions (should not be reported)
reset
The command blkzone reset is used to reset one or more zones. Unlike
sg_reset_wp(8), this command operates from the block layer and can
reset a range of zones.
open
The command blkzone open is used to explicitly open one or more
zones. Unlike sg_zone(8), open action, this command operates from
the block layer and can open a range of zones.
close
The command blkzone close is used to close one or more zones. Unlike
sg_zone(8), close action, this command operates from the block layer
and can close a range of zones.
finish
The command blkzone finish is used to finish (transition to full
condition) one or more zones. Unlike sg_zone(8), finish action, this
command operates from the block layer and can finish a range of
zones.
By default, the reset, open, close and finish commands will operate
from the zone at device sector 0 and operate on all zones. Options
may be used to modify this behavior as explained below.
The offset and length option arguments may be followed by the
multiplicative suffixes KiB (=1024), MiB (=1024*1024), and so on for
GiB, TiB, PiB, EiB, ZiB and YiB (the "iB" is optional, e.g., "K" has
the same meaning as "KiB") or the suffixes KB (=1000), MB
(=1000*1000), and so on for GB, TB, PB, EB, ZB and YB. Additionally,
the 0x prefix can be used to specify offset and length in hex.
-o, --offset sector
The starting zone specified as a sector offset. The provided
offset in sector units (512 bytes) should match the start of a
zone. The default value is zero.
-l, --length sectors
The maximum number of sectors the command should operate on.
The default value is the number of sectors remaining after
offset. This option cannot be used together with the option
--count.
-c, --count count
The maximum number of zones the command should operate on. The
default value is the number of zones starting from offset.
This option cannot be used together with the option --length.
-f, --force
Enforce commands to change zone status on block devices used
by the system.
-v, --verbose
Display the number of zones returned in the report or the
range of sectors reset.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
