I made some tests to see how ext3 reiserfs 3.6 and jfs survive disk errors. The test is simple: format a partition, copy the kernel source, unmount and and do ?dd if=/dev/zero of=/dev/hdd bs=512 count=100000 seek=30000? to simulate a disk surface damage and then run fsck. seek=30000 ? this must be the second half of journal in reiserfs and ext3, for jfs I don't know Result: jfs: ---- total data loss, can't mount, fsck didn't helps reiserfs: --------- doing ?reiserfsck ?rebuild-tree? moves all recovered data in lost+found, but information is almost unusable ext3: ----- after ?fsck.ext3 -f -y? almost everything was usable, directory structure was untouched, some files was moved in lost+found, but in general everything was usable. My opinion: I can't use anything but ext2/3 in a system where there is no RAID ? 99% of desktops and most of web and mail servers.
