Renaming issues ...

Hello,

Sorry for the english, I am still not speaking spanish
I wanted to share an issue I spotted with some special characters (I think).
I regularly record Dr House on the French HD DTT and the last time I did, I got a fil I could not play (with the film roll and the interrogation mark). I therefore launched the FTP, to get the file back on my pc and to check what was happening (I had a similar issue with a film that began to record when my aerial was "down" and then back, and it was previewed ok, played by vlc on my pc, but I couldn't launch it with the normal PLAY command, nor edit it with TS Doctor _except in RAW Mode_ etc.).

I then saw it was a 11G file (cool, there are data in it ), and tried to FTP it with Filezilla.
I couldn't!
I thought this was related to the name of the File: Dr House. _EcorchÃs vifs__20100511_2045.ts (I already had issue with that earlier, FTPing a file with special characters in the name and getting a blank icon, with a partial name and no mean to delete it or rename it).

So I decided to rename it via FTP. I couldn't.

Ok, so I decided to rename it via a telnet sessions:
mv ./Dr\ House.\ _EcorchÃs\ vifs__20100511_2045.ts ./DrHouse.ts
mv: unable to rename `./Dr House. _EcorchÃs vifs__20100511_2045.ts': Operation not permitted
(I even chmod ugoa+rwx in case, also tried cp rather than mv...).
I couldn't.

So I decided to rename it via LG interface on my TV ... I still couldn't. (Echec de renommer!)

I think I more or less did everything I could there till modyfing my default busybox (if mv/cp/etc. are commands in it) hoping there is one dealing better with bloody characters that are sent via EPG and not understood correctly by the system.

If anyone has a magic command I couldn't think of, before modifying my system :-( , I would be more than thankful!

I am pretty sure I already had the issue with other programs.

Cheers,
Matt

PS: I also tried via Samba, since the file name looks better (identical, I think, to how it looks on the LG interface): Dr House. _Ecorchés vifs__20100511_2045.ts
"You need an authorisation to perform that action" (free translation from french error message )
Of course in all cases, my target name was very simple: DH.ts (no space, no special characters, etc.)

PPS: I just wondered why I do not go to the LG SAV about this rather than coming here ... I think you know why

Phewww,
not sure if I understood.

When you use the mv command, you write the long filename by hand, or completed with TAB ?

Try to mv like this : mv Dr*.ts new_file.ts

But I am afraid you have a kind of corruption in that file.
Does it allow to delete the file?

Did not work with busybox 1.9.1 i got on moviecube.free.fr:

./busybox1.9.1 mv ../REC/Dr House. _EcorchÃs vifs__20100511_2045.ts ../REC/DR_HOUSE.ts
mv: cannot rename '../REC/Dr House. _EcorchÃs vifs__20100511_2045.ts': Operation not permitted

./busybox1.9.1 cp ../REC/Dr House. _EcorchÃs vifs__20100511_2045.ts ../REC/DR_HOUSE.ts
cp: cannot stat '../REC/Dr House. _EcorchÃs vifs__20100511_2045.ts': Value too large for defined data type

./busybox1.9.1 mv "../REC/Dr House. _EcorchÃs vifs__20100511_2045.ts" ../REC/DR_HOUSE.ts
mv: cannot rename '../REC/Dr House. _EcorchÃs vifs__20100511_2045.ts': Operation not permitted

I run out of ideas to test ^^ If you have any...

@Victor, thanks but not working :-/
I indeed used tab to complete the name, but also tried earlier with *
Here is the result:

mv ./Dr*.ts ./DrH.ts
mv: unable to rename `./Dr House. _EcorchÃs vifs__20100511_2045.ts': Operation not permitted

And I did not dare trying deleting the file want to get it to analyze it first :p

Hmmm
No, I can not even detele it ^^

Now you have plenty of time to analize

Interesting...
I think this issue can happen to anyone, and you will have a nice file there for ever.
Let me test later at home a : fsck to see if it is installed in the system.

Lol, indeed!!

I am wondering whether I had a journal issue, or something similar. But I don't know how to force a check with the usfd type of the partition.

fsck is in the system:
/tmp/hdd/volumes/HDD1 # fsck
fsck 1.38 (30-Jun-2005)

But no help, gonna look for this command on Internet

Ok, should I try:
fsck /tmp/hdd/volumes/HDD1

!!!!! Attention!!!
do not fun the fsck command will the disk is mounted!!! you can loose all your Dr. House's chapters and all
Let me test this later at home with the test unit.

also interesting will be if exist the command e2fsck.

Ok, I'll wait then

Yep, the command exists:

e2fsck -h
e2fsck: illegal option -- h
BusyBox v1.1.3 (2009.11.18-08:46+0000) multi-call binary

Usage: e2fsck [-panyrcdfvstDFSV] [-b superblock] [-B blocksize] [-I inode_buffer_blocks] [-P process_inode_size] [-l|-L bad_blocks_file] [-C fd] [-j external_journal] [-E extended-options] device

Check a Linux ext2/ext3 file system.

Options:
-p Automatic repair (no questions)
-n Make no changes to the filesystem
-y Assume 'yes' to all questions
-c Check for bad blocks and add them to the badblock list
-f Force checking even if filesystem is marked clean
-v Be verbose
-b superblock Use alternative superblock
-B blocksize Force blocksize when looking for superblock
-j journal Set location of the external journal
-l file Add to badblocks list
-L file Set badblocks list



But as far as I know, the filesystem is not ext2/3, is it?

OK,
do not have the solution yet,
but let me explain what i have found so far.

My mount command shows:
/ # mount
/dev/root on / type squashfs (ro)
none on /dev type devfs (rw)
none on /proc type proc (rw,nodiratime)
devpts on /dev/pts type devpts (rw)
none on /sys type sysfs (rw)
/dev/mtdblock/2 on /usr/local/etc type jffs2 (rw,noatime)
none on /tmp type ramfs (rw)
/dev/rd/0 on /mnt/rd type vfat (rw,nodiratime,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1)
/dev/scsi/host1/bus0/target0/lun0/part1 on /tmp/hdd/volumes/HDD1 type ufsd (rw,nodiratime)
/dev/scsi/host1/bus0/target0/lun0/part3 on /tmp/hdd/livepause type udf (rw)
/dev/scsi/host1/bus0/target0/lun0/part4 on /tmp/hdd/root type ext3 (rw)


so, first, lets umount HDD1 with:
/ # umount /tmp/hdd/volumes/HDD1/



Now the mount command shows all, but HDD1:
/ # mount
/dev/root on / type squashfs (ro)
none on /dev type devfs (rw)
none on /proc type proc (rw,nodiratime)
devpts on /dev/pts type devpts (rw)
none on /sys type sysfs (rw)
/dev/mtdblock/2 on /usr/local/etc type jffs2 (rw,noatime)
none on /tmp type ramfs (rw)
/dev/rd/0 on /mnt/rd type vfat (rw,nodiratime,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1)
/dev/scsi/host1/bus0/target0/lun0/part3 on /tmp/hdd/livepause type udf (rw)
/dev/scsi/host1/bus0/target0/lun0/part4 on /tmp/hdd/root type ext3 (rw)


Now I have tried several commands to check the filesysetm but no success yet:
/ # fsck /dev/scsi/host1/bus0/target0/lun0/part1
fsck 1.38 (30-Jun-2005)
fsck: fsck.ntfs: not found



/sbin # fsck.ext3 /dev/scsi/host1/bus0/target0/lun0/part1
e2fsck 1.38 (30-Jun-2005)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext3: while trying to open /dev/scsi/host1/bus0/target0/lun0/part1



/sbin # fsck.ext2 /dev/scsi/host1/bus0/target0/lun0/part1
e2fsck 1.38 (30-Jun-2005)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext2: while trying to open /dev/scsi/host1/bus0/target0/lun0/part1




We are near the solution
too tired now, ...
probably taking off the hard disck and checking from a PC ... ??

Hi Victor,

Many thanks for your investigations!
The issue is that I have a MS450H and as far as I understood this partition is on the internal disk, so I should open the box to check it.

I'll do it as a last option (we are still using it for the time being ^^).

Cheers,
Matt

yes,
lets see if among everybody we are able to scan/fix a HD, because I am sure this is very usefull.

I will try later to scan in a mounted HDD1 in test unit, to see what happens.

still investigation,
see what do we have so far:

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

fsck.ext2: Warning... fsck.ext2 for device /tmp/hdd/volumes/HDD1/ exited with signal 11.

Do you really want to continue (y/n)? n
no

So whentryging to check while mounted, it says wants to continy, very dangerous yes or no?

very scary
, but if i try having it unmounted it trhows out a segmentaion error.
strange

if i say yes, same error

So, it seems HDD1 is not ext2, I think some where is specifiy the type of format, i do not remember now. NTFS ????

vic1972 escribió:

It seems so, UFSD would then be related to the Paragon UFSD NTFS (Universal File System Driver, rather than Unix File System D???).
I also checked by connecting an NTFS formatted USB key on the MS450H:
~ # mount
/dev/root on / type squashfs (ro)
none on /dev type devfs (rw)
none on /proc type proc (rw,nodiratime)
devpts on /dev/pts type devpts (rw)
none on /sys type sysfs (rw)
/dev/mtdblock/2 on /usr/local/etc type jffs2 (rw,noatime)
none on /tmp type ramfs (rw)

/dev/scsi/host2/bus0/target0/lun0/part1 on /tmp/usbmounts/sdc1 type ufsd (ro,nodiratime)


So, I am now searching on the Internet how to check/repair the NTFS filesystem under linux xD

fsck.ntfs <= does not exist on the LG
but ntfsfix does:
ntfsfix -h
ntfsfix v1.13.1 (libntfs 9:0:0)

Usage: ntfsfix [options] device
Attempt to fix an NTFS partition.

-h, --help Display this help
-V, --version Display version information

For example: ntfsfix /dev/hda6

Developers' email address: linux-ntfs-dev@lists.sf.net
Linux NTFS homepage: http://www.linux-ntfs.org

I'll look for the man pages...

Cheers,
Matt

I first try on my USB key

Umounting it (tried without at first and some failures plus terrible messages as expected ):
umount /tmp/usbmounts/sdc1

Then "fixing":
ntfsfix /dev/scsi/host2/bus0/target0/lun0/part1

Log:
Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
NTFS volume version is 3.1.
Setting required flags on partition... OK
Going to empty the journal ($LogFile)... OK
NTFS partition /dev/scsi/host2/bus0/target0/lun0/part1 was processed successfully.


Do you think I should try on my HDD1 partition?

ntfsfix doc pages:
FR: http://doc.ubuntu-fr.org/ntfsfix
EN: http://man.linux-ntfs.org/ntfsfix.8.html

I am afraid this is not a very powerful tool ...

Hello,
very interesting.

I have done to my HDD1, of course unmounted, anyway I also tried mounted
See the trace below:


/ # umount /tmp/hdd/volumes/HDD1
/ # ntfsfix /tmp/hdd/volumes/HDD1
Mounting volume... Error opening partition device : Is a directory
Failed to startup volume : Is a directory
FAILED
Attempting to correct errors... Error opening partition device : Is a directory

Volume is corrupt. You should run chkdsk.

/ # ntfsfix /dev/scsi/host1/bus0/target0/lun0/part1
Mounting volume... OK

NTFS volume version is 3.1.
Setting required flags on partition... OK
Going to empty the journal ($LogFile)... OK
NTFS partition /dev/scsi/host1/bus0/target0/lun0/part1 was processed successfully.


So, ntfsfix seems to be working
After, that i have rebooted, and media in HDD1 if fine, as i have been able to reproduce.

Thanks ^^
I just tried:
~ # umount /tmp/hdd/volumes/HDD1
~ # ntfsfix /dev/scsi/host0/bus0/target0/lun0/part1
Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
NTFS volume version is 3.1.
Setting required flags on partition... OK
Going to empty the journal ($LogFile)... OK
NTFS partition /dev/scsi/host0/bus0/target0/lun0/part1 was processed successfully.
~ # reboot

Then loging again:
/tmp/hdd/volumes/HDD1/REC # ls
BIENVENUE CHEZ LES ROZES_20100110_2035.ts
C'est ma terre_20100512_2035.ts

mv: unable to rename `Dr House. _EcorchÃs vifs__20100511_2045.ts': Operation not permitted
/tmp/hdd/volumes/HDD1/REC #

so, it seems is doing something, but it seems no effect ....
strange, well, out of ideas for the moment.

I tried to read a bit Parangon stuff:
http://download.paragon-software.com/doc/manual_ntfsl_eng.pdf

I then tried to umount / remount partition with different codepage, iocharset, etc. to try to have names with no weird characters (in case) but it seems I do not mount things correctly, since I can umount a ufsd/ntfs partition, but I am not able to remount it, despite using mount -t ufsd /dev/... /tmp/... (with ... replaced by the right paths )

Wondering about moving the working movies from the folder to the other HDD and to reset it via the LG "installation" menus

Cheers,
Matt

Hello,
yes, that is of course the best solution, at this moment ....
It will be nice to be able to "fix" the hard disk errors, we will have to keep investigations.

Yes, move the staff to the other hard disk, then extrack it from lg (just to be sure which is the disk you are formating), then format, and then
copy back the movies ...
I understand this would take a lot of time the copy process, probably best if you leave it in the night in the copy process.

See you
Victor

Hi,

What I did is the following: I moved the files not corrupted (by that time, only one remained uncorrupted, the three others were not movable ...) and lauched two "initialisation" via the LG menu on my internal hard disk.
Will monitor whether I have the issue again or not, and if yes will extract the HDD and plug it to a pc...

Weird.

Cheers,
Matt

Imdeed, I have just unxuccessfully tried

Código:

umount /tmp/hdd/volumes/HDD1/
mount /dev/sda1 /tmp/hdd/volumes/HDD1/ -t ufsd

Has Anybody found how to mount the ntfs partition (/dev/sda1 on /tmp/hdd/volumes/HDD1/) ??

Thanks,

Hi!
Not me, unfortunately :-/
Cheers,

evr escribió:Has Anybody found how to mount the ntfs partition (/dev/sda1 on /tmp/hdd/volumes/HDD1/) ??

I reply to myself: The missing option to mount was "-o force". This is the minimal expression:

Código:

mount -t ufsd -o force /dev/sda1 /tmp/hdd/volumes/HDD1

And this is what I found somewhre googling around:

Código:

mount -t ufsd -o force -o rw -o sparse -o nls=utf8 -o umask=0000 /dev/sda1 /tmp/hdd/volumes/HDD1

Best,
