File System Character Encoding probleem....

Ik heb dus een Character Encoding probleem.

Ik heb hier 4 files in een dir staan, op 0 byte.
Die staan in het rood. Ik kan zeniet wissen, niet verplaatsen, en ook niet hercoderen met convmv.
Tenm niet met wat ik heb geprobeerd....
'convmv -f utf-8 -t utf-16'
> 'Can't find file.....'

Ik heb het van een ReiserFS partitie gecopieerd naar een JFS partitie, over NFS heen.
Die Reiser gebruikt geforceerd, UTF-8, maar kent verder intern geen character encoding. JFS gebruikt intern utf-16.
Vandaar dat ik met convmv van utf-8 naar utf-16 heb geprobeert om te zetten.

SuSE gebruikt nog niet al te lang UTF-8 encoding. Voordeel hiervan vind ik, is dat je aale standaard characters kunt lezen. Gaat dus veel verder dan bv ISO8859-1, die niet verder komt dan de U.S. characters. Wil ik de bv Noorse kunnen lezen, ben ik geloof ik, ISO8859-8 nodig.....

Dat is wat ik tot nu toe heb uitgezocht....
De bedoeling is dat de dir word gewist waar de files in staan. En dat lukt nou voor geen meter!

Ik weet wel, dr lopen hier maar een stuk of 10 linux fanaten rond, maar miss weet 1 van die 10 meer.

ff "fsck.jfs -f" runnen zou ik zeggen.

Aha!

Als dat nou alles is......


Zal eens proberen!


Als ik het zo lees, is dat een forced-check?

Ik had met optie -p (preen) gescand.....

Heb het probleem nog steeds....

Heb gedaan: fsck -f /dev/hdd1

Files blijven staan.,...

Begin echt het idee te krijgen, dat het FS over bep. characters struikeld.

Ik zal wel ff: jfs_logdump -a /dev/hdd1, draaien....
Kijken wat dat zegt.....

Nou ik heb een logdump gedaan, en krijg een file van meer dan 200MB!!!

'k Zal mar niet de HELE log hier neerzetten....
(zal niet eens lukken denk ik..)

Ik zal en klein stukkie plaatsen, want ik snap dr helemaal niets van....

En dit is dan maar een gedeelte....

Voor het deleten van een file is de inhoud niet belangrijk hoor. Het FS maakt het helemaal niets uit wat in de file staat.

Welke rechten staan er eigenlijk op de files?

Da's nou net het probleem! Ik KAN hem niet deleten.

De Inodes van die files staan op null.
Ik zie hier in Midnight Commander de files n het rood staan met een ? ervoor....

Ik heb tot nu toe begrepen, dat de METADATA niet goed is bijgewerkt. WAT dat prcies inhoudt weet ik niet.
Miss dat dat gesunct moet worden. Maar HOE ik dat dan moet doen weet ik niet. En zoveel documontatie vind ik er ook niet over. Wat ik wel can vinden is, is dat het een YOUNG FS is. Voor het grootste gedeelte nog in ontw. fase.
Het is geen BETA meer, maar sommige dingen lopen niet, zoals dat behoord te doen. Met name zit dat nog in de Character Encodering.

En het klopt wel wat je zegt, dat de INHOUD niet belangrijk is...
Maar het gaat nu om de FILENAAM. De encodering daarvan slaat de mist in! Waardoor het FS id problemen komt, op de 1 of andere manier....

Maar ik lees ook, dat XFS, beter doorontwikkeld is dan JFS.
En heeft ongeveer dezelfde snelle recovery als JFS.
En XFS heeft ook tools om de MataData te syncen.
Dr staat nl in de faq wat te doen, als je na een recovery, files vind die op null byte staan.

Moet ze allebeide maar eens nader onderzoeken.....
