- usage: blkdiscard [-olszf] DEVICE
-
- Discard device sectors.
-
- -o, --offset OFF Byte offset to start discarding at (default 0)
- -l, --length LEN Bytes to discard (default all)
- -s, --secure Perform secure discard
- -z, --zeroout Zero-fill rather than discard
- -f, --force Disable check for mounted filesystem
-
- OFF and LEN must be aligned to the device sector size.
- By default entire device is discarded.
- WARNING: All discarded data is permanently lost!
