changing ownership : operation not permitted

hi all
i am here -lfs6.7 @ 5.33. Changing Ownership (pagno-73)

1)I wanna take back up $LFS/tools directory (for use in building future LFS systems), how can i take back up (tools dir)
i mounted pendrive to /tmp
i try to copy the tools dir to /tmp: msg permission denied
lfs:/mnt/lfs$ls
sources tools lfs-packages.tar
lfs:/mnt/lfs$cp -r tools /tmp(usb device mount point)

2)i am try to change the ownership of the $LFS/tools directory to user root by running the following command:

lfs:/mnt/lfs/sources$ chown -R root:root $LFS/tools

output is lenghty,but i am posting last lines only

You missed the Note at the beginning of chapter 5.33.

hi druuna
thanku so much for fast reply

(i am using lfs livecd)
yes that may be the mistake
(present) one terminal is lfs usr,
so i opened new terminal
here i run this
root[ ~ ]#chown -R root:root $LFS/tools
is this fine
i have to do chpter 6 @ root[ ~ ]# only right
-----------------------------------------------
i was expecting abt backup tool dir,can u tell

thanku

I'm sure that is the mistake....

That is the command in the book, just make sure the LFS variable is set (probably to /mnt/lfs).

I do believe that is what the note in chapter 5.33 says.

Quote:

What did you expect? The book only mentions this would be a good point to make a backup.

If you want to make a backup I would suggest the following (as root user):

Code:

cd /mnt

tar jcf lfs.chapter5.tar.bz2 lfs

If, for whatever reason, you want to start at the beginning of chapter 6 again do the following to restore the backup (as root user):

Code:

cd /mnt

rm -rf lfs

tar jxf lfs.chapter5.tar.bz2

Hope this helps.

hi druuna
i exit from lfs user,now
root [ /mnt ]# tar jcf lfs.chapter5.tar.bz2 lfs
output is following

bzip2: I/O or other error, bailing out. Possible reason follows.
bzip2: No space left on device
Input file = (stdin), output file = (stdout)

how come this,i made 12gb partition for lfs ,
shall i remove sources dir(all previous pkg untared sources)? in /sources
-------------------------------------------------------------------------

You should remove the build dir as you go along

hi druuna
(i am using lfs livecd)

here i just click on logout(on menu),after few seconds
its appear as root[ ~ ]#
here i typed
root[ ~ ]#startx
reslult is
FAT:directory bread(block 5991904) failed
scsi ....rejecting i/o to dead device
.
.
.
.
FAT:directory bread(block 5991904) failed
scsi ....rejecting i/o to dead device
FAT:FAT read failedblocknr 3820)
fatal server error:
could not create lock file in /tmp/.tx0-lock
give up.
xinit:no such file or directory(errno 2):unable to connect to x server
xinit:no such process(errno 3):server error.

something went wrong a?
when i type startx @ root [ ~ ]#
it should appear gui na
whats wrong

You need to build blfs yet, The lfs is just the base system

Don't use fat. Format the drive in a Linux filesystem. The chown command will not work. The ownership and permissions of directories and files are determined enmass by the mount options.

However, you could backup up files to a fat drive using tar. The ownership and permissions information is written inside the backup.

If you are using the liveCD there is indeed no space left to do the tar command (when using /mnt/lfs.chapter5.tar.bz2 as target). You cannot write to a cd, it is a read-only medium.

If you have a memory-stick or thumb drive or whatever, mount it first (for example to /mnt/usbstick), then tar to that mounted directory (again as root):

Code:

cd /mnt

tar jcf /mnt/usbstick/lfs.chapter5.tar.bz2 lfs

PS: You should always remove the build directories after the build (which is mentioned in the book), but you do not need to remove the packages.

Hope this helps.

hi druuna

yester day i told ,i got fat error
so today i started fresh from starting
see 5.33(lfs-6.7)
note(pagen0-73)
The commands in the remainder of this book must be performed while logged in as user root and no
longer as user lfs. Also, double check that $LFS is set in root's environment.

lfs:/mnt/lfs/sources$exit(i exited from lfs)
root[ ~ ]#chown -R root:root $LFS/tools
root[ ~ ]#echo $LFS
its iving /mnt/lfs
it should show root na according to note

hi druuna
one more thing
till chapter 5 only i have to use lfslivecd(without distrubing,without power off)

while doing chapter 6 ,doesnt need to use lfs livecd ?right
is this right what i am saying,
if so how can i start ch6 without using lfscd
plz tell me as above(step wise plz)
thanku

That depends on what you mean by "it". $LFS/tools should now be owned by root.

No, that is incorrect, you still need the liveCD.

hi
druuna
thanks for reply

i used lfslivecd(continue) ...(lfs-6.7)

@6.2.2. Mounting and Populating /dev

root [ ~ ]# mount -v --bind /dev $LFS/dev
result is following
/dev on /dev type none (rw,bind)
is this right (i didnt get 'none' word),nothing wrong this one right?

shall i go forward,

Hi,

If there is no error shown you can continue.

The above shown output is not an error, it is the output generated by the -v (verbose) flag.
