New to NILFS2

[Nelson Sicuro]

Hi everyone

I started using NILFS2 version 2.0.14 this month on Ubuntu 8.04 and 8.10  
distros (2.6.24-24-generic 64 bits), so far so good.

I looked at the new's archives and find some interesting questions about  
deleting more than one CP at a time. Can I use this feature on my distro  
or do I need to recompile nilfs-tools? May this feature be included on  
Ubuntu 9.04?

Best regards and congrats for the excellent job!

I don't belive this is in Jaunty yet since this only recently went in in 
Ryusuke-san's git tree. So yes, you would have to recompile this 
yourself (easily done). Beware however that deleting the checpoints are 
only cosmetic at the moment (i.e. you won't see them in a 'lscp' output) 
and you still need to wait for the cleanerd to reclaim space.

Unfortunately I don't have contact with Ubuntu maintainers, so I
cannot mention the release plan.

But, yes, the CP deletion feature is available from our git repo.  The
belief instruction is shown in the following page:

http://www.nilfs.org/git/

I also recommend you to apply the current head of nilfs2-module.git
available if you use the git repo since it includes an important
performance improvement patch.  Anyway, I'm planning to release both
updates next week unless I'm busy.

Thanks for the tip, I compiled the tools and it worked, following the  
site's instructions. There is any directions to build the module?

Best regards,

If you don't want to recompile , Just use seq with xargs :
#seq <start> <end> | xargs rmcp

Or If you don't want to type a lot : (untested)
function rmcpg {
seq $1 $2 | xargs rmcp
}

There's probably a better way If I actually knew how to script.
