Re: [gentoo-amd64] Ext3 to ext4

[Martin Herrman]

Hi Nathan and Florian,

thanks for both your replies. 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
