Hi guys!
I'm pulling a compressed (gzip -9) disk image over the LAN and
decompressing prior to writing to disk with dd.
The command I am using is
ssh [EMAIL PROTECTED] "cat client.img.gz" | gunzip | dd
of=/dev/hda1
This seems to work reasonably well until it gets somewhere around the 1G
mark at which point everything seems to have slowed down to a crawl.
The result is that it takes nearly as long as when I don't compress it
and just pull the whole 8G partition through ssh.
I'm guessing it's something to do with buffering of the data in gunzip
prior to it getting to dd that's blowing things up.
Anyone got any clues on how to do this more on the fly so all data is
passed through without any buffering?
Why is this sort of question always late on a Friday?
Oh well, have a good weekend!
