Status of Reiser4?

Status of Reiser4?

[ANDY KENNEDY]

All,

Google didn't help me much in my search for information, though I admit
to not being the greatest at searching the net.  I'm a long-term user of
ReiserFS but after moving to a multi-core processor, I'm experience less
than desirable performance.  BTW, quick shout-out:  Been using ReiserFS
3.4 for ~12 years and I have only ever had ONE problem with it (and it
wasn't the FS's fault -- a disk pack failed repeatedly during a reboot
caused by a RAID drive failure -- I was able to recover 100% of the
data, though it took a LONG TIME ;) ).

In my search on the web, I have seen that there is still life in Reiser4
but being adopted into the main-line kernel has stalled/met opposition.
Is Reiser4 ready for a production machine?

Thanks in advance for the information,
Andy

Make sure that you have the latest stuff (reiser4-for-2.6.39) and
tail packing is turned off (format your partition with the option
-o "formatting=extents"). In this configuration it should work.
Once everything gets stable, we'll turn it on via mount option. If
something goes wrong, then let us know..

Reiser4 doesn't have scalability problems inherent to ReiserFS (v3)
because of using progressive algorithms.

Thanks,
Edward.
