Running / in ext4 now :-) tunefs command was really quick (which I didn't expect), but during the reboot I had to run an fsck manually. Dmesg now shows me that the filesystem has some unknown attributes to ext3 and next mounts it as ext4. Just another 2 questions: - Florian, what kind of tuning for raid-0 are you pointing at? (i only have the noatime in /etc/fstab) - I read that increasing the commit field will increase the amount of data that can be lost in a power failure, but increases performance. When I put it in /etc/fstab, for example with a value of 30 seconds, the /etc/mtab file shows me 'noatime,commit=30,noatime=0'. Dmesg final line says "EXT4-fs (md3): re-mounted. Opts: commit=0". Should I increse this value, and how? Thanks, Martin
