I've run into a strange problem either with diff or with the file system. I have an iso image of a gzipped file called db.iso. If I copy that file to a new file on the same partition and run diff, it tells me they differ. Also, when I copy the file via nfs(see example below for /fs2-backup/), it corrupts the gzip, but not when I scp the file. Any help would be greatly appreciated! Here are a few examples: [root@walt mysql_archive]# cp db.iso db.iso-1 [root@walt mysql_archive]# diff db.iso db.iso-1 Binary files db.iso and db.iso-1 differ [root@walt mysql_archive]# cp /boot/vmlinuz-2.4.18-3 . [root@walt mysql_archive]# diff /boot/vmlinuz-2.4.18-3 vmlinuz-2.4.18-3 [root@walt mysql_archive]# [root@walt mysql_archive]# cp vmlinuz-2.4.18-3 timma [root@walt mysql_archive]# diff vmlinuz-2.4.18-3 timma [root@walt mysql_archive]# [root@walt mysql_archive]# cp db.iso ../ [root@walt mysql_archive]# diff db.iso ../db.iso Binary files db.iso and ../db.iso differ [root@walt mysql_archive]# cp db.iso /opt/ [root@walt mysql_archive]# diff db.iso /opt/db.iso [root@walt mysql_archive]# [root@walt mysql_archive]# cp /fs2-backup/db.iso . [root@walt mysql_archive]# mount -t iso9660 -o loop db.iso /mnt/cdrom1/ [root@walt cdrom1]# gunzip -c nea.dmp.gz > /opt/burn/nea.dmp gunzip: nea.dmp.gz: invalid compressed data--crc error gunzip: nea.dmp.gz: invalid compressed data--length error [root@walt mysql_archive]# umount /mnt/cdrom1/ [root@walt mysql_archive]# scp fs2:/backup/db.iso . root@walt mysql_archive]# mount -t iso9660 -o loop db.iso /mnt/cdrom1/ [root@walt cdrom1]# gunzip -c nea.dmp.gz > /opt/burn/nea.dmp [root@walt cdrom1]# This is really frustration because this is a weekly archive of our database exports and most of the time, the gzipped file on the cd is corrupt even though I can gunzip the original file.
