Cpio restore I/O read error

Cpio restore I/O read error

Cpio restore I/O read error


I am trying to resolve a problem on a sco unix box in the Falklands. I have just received a backup from them to load onto my box so that I can try to resolve their problem.

The command I use to restore the data is cpio -idcuvB < /dev/rStp1

The tape device engages but I get the error message
cpio: I/O error on read()
I get the same error if I try to read the tape cpio -ivt < /dev/rStp1

Any help/advice would be much appreciated.


RE: Cpio restore I/O read error

Assuming the tape is at room temperature, try a:
 tape reten /dev/xStp1
then retry the cpio -itv < /dev/rStp1.

if it still fails:
- try it on a different tape drive.
- get another backup.

RE: Cpio restore I/O read error

You may also explore the dd command and try to move the raw data file to disk. Then try the cpio from the disk file.

RE: Cpio restore I/O read error

Are you sure it's a cpio tape ? Just out of curiosity try the "tar tvf /dev/<your device>"  command and see what happens.


RE: Cpio restore I/O read error

What is the output of |code] dtype /dev/rStp1 ΓΏ ?

RE: Cpio restore I/O read error

do you get an i/o error if you try to:
 cat /dev/rStp1 | more
