Repacker stats
PATCH 1/1 Repacker stats
Hi
This is my second attempt at repacker statistics, this time based on comments from Alex Zarochentsev (thanks ;-).
This patch allows reading of repacker stats while it is working. It creates two files in repacker sysfs hierarchy: formatted_nodes and unformatted_nodes, which correspond to the stats that repacker prints after it has finished.

Hello,
I was interested in testing the repacker statistics tool that Piotr Neuman wrote (and others later added to). But from what I can see the repacker is disabled in 2.6.9-rc4-mm1, because of this patch:
http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc4/2.6.9-rc4-mm1/broken-out/reiser4-disable-repacker.patch
Is there something wrong with the repacker that is has to be disabled?

Currently the repacker is known to corrupt the filesystem, that's why it's disabled, I guess.

There are two reasons:
1) functionality that is not stable should be turned off until it is stable ("...." and repacker both).
2) we aren't making payroll and need something nonessential to bundle with support if we want people to buy support so that I am to be able to quit my day job and pay people. There is nothing less essential yet still salable than a repacker/resizer. ext3 had a proprietary resizer, so it is not an innovation by us.
reiser4 development is going at greatly reduced speed due to our needing to take contracts involving other kernel work rather than working on reiser4. I am basically unable to spend time reviewing reiser4 code because I have this day job fixing things not related to reiser4 in the kernel. I am glad to have the day job, but getting money from our work on reiser4 would be better.....
I have also asked both the EU and the US for money, wish me luck. I'd like to start working on the enhanced semantics for ReiserFS, but I need money to do that. We are losing momentum vs. Apple and MS. The resizer might bring in the money for enhanced semantics work.

Turned off, or perhaps better to be marked as unstable or dangerous. If it isn't available, no one will test and report problems.

This I do understand very well. It brings my thoughts to Diskepper from Executive Software (www.executive.com). Microsoft included a basic version of their defrag software into Windows 2000. Users see the functionality, but they cannot do much with it other than manual defrag. All advanced features usually needed for corporate world is only available if you pay to "upgrade" to full version of Diskeeper.
My suggestion is to leave a basic version of the repacker for normal users, and to offer a more advanced and manageable version for corporate network and server use? More users will see the availability of defrag with Reiser4 and choose it above another fs. In the end, probably, more people/companies would buy the extended features?

I wish you luck. It would be a shame if you would have to quit the work on your filesystems.
