I have recently upgraded 1.3 -> 1.5.10.
All patching was done on our ULTRIX machine. I then tar'ed and
compressed all directories. Now my commands.tar.Z file is 1.24 Mbytes
big.
I have made a file system of size 1450 blocks on a 1.44Mbyte disk, but
when I mount it and say
cp commands.tar.Z /mnt3
I get the following error message :
cp : error 0
Anybody have any idea ??? The file is certainly smaller than the file system
size... (or so it seems...)

There is a (probably unique) bug in cp which would cause "error 0". It doesn't allow for partial writes. However, I don't see how a partial write could be caused by the above setup. In Minix, the only partial writes that I can remember occur when writing past the end of a disk device. For these, the bug would only cause cp to report an error one step too early. -- Bruce Evans Internet: brucee@runxtsa.runx.oz.au UUCP: uunet!runxtsa.runx.oz.au!brucee (My other address (evans@ditsyda.oz.au) no longer works)

When I formatted the disk under DOS, it actually formatted to 1.451Mbytes. Therefore I made a 1450 block size file system on the disk. This still does not explain the error message. Marcus Schnell

On my Unix system at home I have 1.2Mb diskettes. They format to 1260blocks if I remember correctly. But only when I access the raw device. I run mkfs on them which creates the i-nodes and file system structure. I let mkfs decide on how many i-nodes based on the size of the file system specified. On my unix system I would use df or fsck to tell me the number of unused blocks available. after the whole procedure. I will check this on my unix and my minix tonite. -- **************************************************************************** Kerry F Owens US Address BRD Address Internet Address Box 453 Brand Str 13 owens@unix1.j6.eucom.mil APO NY 09128 7032 Sindelfingen 7
