[gentoo-user] Labeling reiserfs partitions

[gentoo-user] Labeling reiserfs partitions

[Meino Christian Cramer]

Hi,

 is there a way to label partitions which have already been formatted
 with mkreiserfs and have data on it ?

 The manpage does not make that clear enough for me to check it on 
 a running system......

 Kind regards,

You can always run mkreiserfs and, after that, restore the data with reiserfsck.

 At least for me, this does not work! 
 I applied mkreiserfs -l "root" to a SATA disk with the root fs on
 it and later reiserfsck. reiserfsck did not find any inconsistency
 because

						ALL DATA WERE ERASED !!


********************************************************************

 The question remains:
 How can I apply a label to an alreasy populated reiserfs-partition ???

Of course, that's what mkreiserfs is for. AFAIK mkreiserfs also tells you so 
and even asks for confirmation. The rest is up to you.

Wouldn't it have been safer to have tried it on a USB stick first?

Anyway, the command you want is "reiserfstune --label ...".

  ...I did copy the whole rootfs to a previously total empty SATA
  disk and used THAT hd for experimenting...

  I am not /that/ blind...



  But the idea, which was posted, was (cite):

  "You can always run mkreiserfs and, after that, restore the data with reiserfsck."

  ...and in this simplified form it do harm systems.

OK. Yes, that was pure bull...

At least if you follow it blindly.

Yeah, I think janusz meant to say something like reiserfsck
--rebuild-tree.  But it was still an incredibly stupid thing to
recommend someone else to do...

:-)

I prefer to do such filesystem experimentation on a USB stick, loop
device or spare LVM partition. Any action involving the words "untested"
and "root" is to be rigorously avoided :)

Sure, I was temporarily 86'd from the list for being
a 'bone-head' about iptables.........

I'm still hard-headed, I just try to keep 'issues'
to myself........

On another note, frequent  creation and updates to 
wikis allows for quick responses to these sort
of recurring questions.  If the talented
folks create such wiki pages, the bone-heads could 
easily learn to refer questions to the wikis in
lieu of all of this repetition, and misguided
responses.... Furthermore, ordinary gentoo-linux
readers could volunteer to maintain these wikis,
thus reducing the burden on the pool-o-genius.....
Perhaps a tool like eix/esearch that first
(priortizes) searches for official/unofficial wiki-responsed 
to these common questions?

Furthermore, it would attract more folks to Gentoo.

hth,

James

There are three common problems left for those like me asking
"repetitioned questions":

1.) Most search engines of wikis are as "bone-headed" as those trying 
    to answer the question like the above example. Search engines dont 
    understand any context.

2.) For one not being a native English speaker it is often difficult
    to get the right words for the right match.

3.) Sometimes one can describe the problem without the faintest idea
    of any keyword to be filled into such [CENSORED] search engines.

Without the evolution of search engine into finding enginges mailing
lists will exist, where questions are answered more than once.

Kind regards,
mcc

This was meant to reference inappropriate 'attitudes'
I unwisely shared openly. It was not 
meant to characterize those persons with questions
and/or language barrier issues.....

this is not a search engine proposal. I use the word 'search' in
its generic meaning, not specifically relating to 'search-engines'.

English (US) is my native language. Struggles with english accompany
most of us, our entire life. Get use to struggles with english.

And that is solved and refined during the ordinary discussions
on gentoo-user.

Maybe I did not articulate the idea clearly. It would not use
traditional search engines, such as google, Jeeves.......

It would be a gentoo tool that runs on your machine like 'eix'

call it 'eix-help <keyword> '

where a typical  keyword might be drive/harddrive/ATA/scsi/ide

so a listed of all of the official and testing
wikis that related to these keywords would be listed. The index 
could be a brief description of the wiki.

Here's a simple script written by Ciaran that allos searching
to get the meanings on the flags. It was posted to this gentoo-user
group some time ago. I put in rooot's .bashrc:

# USE flag settings hack by Ciaran McCreesh:
explainuseflag(){ sed -ne "s,^\([^ ]*:\)\?$1 - ,,p" $(portageq portdir)/prof
iles/use.{,local.}desc; }
alias ef="explainuseflag"
#

So when I want to know what a flag does all I type is

ef <flag>

For example

'ef x264' reveals multiple listings:
Enables h264 encoding using x264 (FFmpeg code)
Enables h264 encoding using x264
Enable x264 codec for mp4live (using x264-svn)
Enables h264 encoding using x264

hmmm, more than one explaination for a flag?



Simple, quite useful and scriptable.


There are lots of folks that answer similar questions over and over
again. Sometimes the answer is long, content-rich, and very
informative, even to those with experience. These 'perls' quickly get 
lost if not harvested quickly.
The linux.gentoo.user search engine I use at gmane.org,
is less than robust, but, at least it is limited to this gentoo-user
list of postings.

Restated simply, I'm suggesting:

1. A simple wiki template be created/cited as a reference for
quick documentation creation.

2. Individuals with some measure of experience/ability populate
the template with subject matter specific information, 
primarily gleaned from this
gentoo-user forum, supplemented with other knowledge.

3. A few keywords be included at the beginning of the wiki.

4. A simple tool/scipt could index these wikis according
to the number of keyword matches; and/or the priorty match
of keywords (that is the most relevant keywords would be
placed a the beginning of the keyword list for a given
specific wiki). The more keyword matches the higher order 
a given wiki would appear in the indexed search result.
(This is not the result of a 'search-engine' search, rather
a result from using a script on your gentoo system' A file
listing somewhat like /var/lib/portage/world could
be employed.

5. Allow ordinary gentoo-users to maintain the wikis, that
is those with reasonable skills and a login/passwd to 
bugs.gentoo.org as an example of a simple control mechanism.

6. Monthly, have a 'higher level' review of the wikis by those
with strong skills to ensure the wikis are current, relevant
and useful. Just look at all those wikis related to
ati/nvidia/xorg and tell me they are all current? Some do
depend on the version of xorg you are running, but they
do not alway clearly state this. Person with extreme knowledge
get too busy to maintain their initial wiki creations, but,
folks that use them are more likely to maintain those docs
and add extra information.


This sort of mechanism would encourage others to participate
in creating a gentoo documentation engine that perpetuates
itself by attracting new folks. Helping them learn through
practical examples and grow, until they start coding and 
'move up' the gentoo expertise ladder say to creating 
ebuilds for testing. It certainly would attact more
folks to gentoo as users.

Also, this sort of structure would enable many more folks
to contribute to gentoo, and those persons with deep skills
could gently correct those with good intentions via documents/wikis.


Who knows if something is created and focused 'on the little 
people' then google just might fund it via their 
'summer of coding' program for aspiring young minds....

just a thought,
ymmv,
hth,
and #!world_peace

If it's a local USE flag, because it's use is specific to each
application defining it, although they are usually very similar.
Global USE flags have a single definition.

WTF!!!  Yeah, in theory, your suggestion might work.  But it would be
like going down stairs by jumping, and then having the doctor fix your
broken legs!!

To answer Meino's question:
reiserfstune -l <new label> /dev/...
