+== NAME
+
+blkverify - verify sectors on a device
+
+== SYNOPSIS
+
+*blkverify* [options] [*-o* _offset_] [*-l* _length_] _device_
+
+== DESCRIPTION
+
+*blkverify* is used to verify device sectors. This is useful in order to provide low level media scrubbing and possibly moving the data to the right place in case it has correctable media degradation. Also, this provides a way to enhance file-system level scrubbing/checksum verification and optinally offload this task, which is CPU intensive, to the kernel (when emulated), over the fabric, and to the controller (when supported). This command is used directly on the block device.
+
+By default, *blkverify* will verify all blocks on the device. Options may be used to modify this behavior based on range or size, as explained below.
+
+The _device_ argument is the pathname of the block device.
+
+== OPTIONS
+
+The _offset_ and _length_ 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.
+
+*-o*, *--offset* _offset_::
+Byte offset into the device from which to start verifying. The provided value must be aligned to the device sector size. The default value is zero.
+
+*-l*, *--length* _length_::
+The number of bytes to verify (counting from the starting point). The provided value must be aligned to the device sector size. If the specified value extends past the end of the device, *blkverify* will stop at the device size boundary. The default value extends to the end of the device.
+
+*-p*, *--step* _length_::
+The number of bytes to verify within one iteration. The default is to verify all by one ioctl call.
+
+*-v*, *--verbose*::
+Display the aligned values of _offset_ and _length_. If the *--step* option is specified, it prints the verify progress every second.
