It doesn't hang forever, just a very long time, like someone's confused milliseconds with microseconds, or some such. Also, when writing to the 2nd tape in a CPIO archive, it doesn't actually write to the tape. systat -vmstat records lots of stuff going to the tape device (a SCSI QIC-525 in this case) very quickly - way beyond the speed it can actually do but there's no actual activity. Dump on the otherhand seems fine. Stephen -- The views expressed above are not those of PGS Tensor.
