I burned the fedora 12 dvd iso twice using wodim.
Both times, it wrote:
3738959872 bytes (3.7 GB) copied, 511.982 s, 7.3 MB/s
whereas the size of the actual iso is
3738935296 bytes - a difference of 24576 extra bytes written,
and this in spite of providing the wodim argument -nopad
Is this "normal" behaviour of dvd burners?
I tried to re-sample an MP3 file from 64kbps to 320kbps :
ffmpeg -i file.mp3 -ac 2 -b 320k new-file.mp3
but the resulting file always comes out at 64kbps.
What's the trick to doing this right?
Can grub boot from a logical partition?
It seems from my reading that it cannot.
But I found that I could in fact boot from /dev/sda5
if I used grub interactively, starting with
then using tab to look for kernel and initrd
and finally booting.
However, if I put exactly the same commands in grub.conf
the boot failed, with "File not found ...".
(Nb I am not using LVM, sda5 is a logical partition
within the extended partition sda4.)
Can some guru explain this to me please.
According to the SMART stats, the single drive in my Fedora server is
starting to fail. Rather than backup, do a clean install, and rebuild,
I'd like to try to clone the existing drive to a new one, then swap in
the new one.
What are the restrictions on doing this and the best way to accomplish
it? I have the Clonezilla Live CD that I use for backup. Will that do
Or will a straight dd do it?
add new drive as PATA slave /dev/sdb
dd -if /dev/sda -of /dev/sdb
change the jumpers on /dev/sdb to match what was /dev/sda
In the dd procedure, I'm not sure what to do if sdb is larger than sda.
