Mathieu et, all ,
Fixes seemed to have fixed the corruption issue thus far. Re-emerging
1000+ packages on Gentoo (tons of small reads/writes on SSD) with no
problems yet. Also, just downloaded the Linux-next patch from this
morning
(https://www.kernel.org/pub/linux/kernel/next/patch-v3.12-rc1-next-20130923.xz)
and applied on top of your Reiser4-for-3.12-rc1 branch recompiled
re-installed NVidia (thanks for fixing that btw!) and resuming compiling
as we speak. Going strong still and fast.
Not sure if it makes much difference but I use no compression just
mkfs.reiser4 -o formatting=smart on SSD drives.
Which version of mkfs (mkfs.reiser4 --version)?
In 1.0.8 compression is enabled by default.
Are there any special options I should be using on SSD arrays?
Addressing the compression angle, does formatting an array with one of
the compression options (lzo perhaps?) have significant overhead?
What overhead do you mean?
Storage space is not a concern however if there is very little overhead
I'd like to backup my data and do some benchmarking. Please advise at
your convenience.
Thanks again,
Chris

I've experienced corruption in the 3.12-rc1 on the git tree and just
did a fsck.reiser4 --build-fs. Also re-downloaded the tree and
recompiled as it looks like you've made changes I'll keep you posted.

In my kernel 3.11 on my git, I have re-implemented an API because I did not
know how to port the reiser4 to the new API (readdir -> iterate).
I did not get any problem with reiser4 or reiserfs -but- after installing
the 3.12-rc1 kernel and rebooting, the kernel was missing and the grub.conf
was total garbage. The /boot is EXT2 on my system.
readdir is for reading dir mostly, I don't know if it's the cause of the
corruption or if it did not sync properly but still, if you want to play
with a ext2 partition and you use the kernel 3.11 from my git, reboot to
another kernel before, just as precaution.
The kernel 3.12-rc1 is not affected if it's because of that readdir API
reimplementation because it's based on the Ivan port + shrinker new API
patchs for reiser4.
