ext2 (and I assume ext3) are both pretty bad at becoming fragmented,
especially when dealing with large files and when the disk starts
getting close to 90% full.
I wonder how JFS/XFS/reiserfs compares... I do know that XFS will
combine multiple small writes into larger ones. The files would be
fragmented less if Myth could pre-allocate disk space of the files in
1MB chunks (or more). I could see especially if you had multiple
tuners, you would quickly end up with some pretty fragmented files.
Anyone know how to find out how many fragments a file contains?
The only way I know how to defragment files is to copy the file, delete
the original and rename the copied file back to the original.
