2.4. cpio
The cpio packages provide the GNU cpio file archiver utility. GNU cpio can be used to copy and extract files into or from cpio and Tar archives.
- The cpio utility uses a default block size of 512 bytes for I/O operations. This may not be supported by certain types of tape devices. If a tape device does not support this block size, cpio fails with the following error message:
cpio: read error: Cannot allocate memory
To work around this issue, modify the default block size with the--block-size longoption, or use the-Boption to set the block size to 5120 bytes. When the block size supported by the tape device is provided, the cpio utility works as expected. (BZ#573943)
