¿fsck.ext3?

[hperez]

Como el deco me está haciendo cosas raras últimamente, estaba pensando en chequear el disco duro por si acaso se hubiera corrompido el sistema de ficheros.

El disco duro está formateado en ext3, pero el deco sólo incluye el comando fsck.ext2, ¿se puede conseguir el fsck.ext3 en algún lado?

Baja cualquier Live cd de ubuntu y listo.

fsck.ext3 /media/hda2 o donde tengas el disco duro

Me refiero a ejecutar el fsck.ext3 desde el propio deco. Para eso necesito un fsck.ext3 compilado para el procesador que lleva.

Estoy viendo que el busybox 1.16.1 lleva un fsck, pero no sé si hace algo:

./fsck -t ext3 -V /dev/hda4
fsck (busybox 1.16.1, 2010-05-25 13:07:21 UTC)
[fsck.ext3 (1) -- ] fsck.ext3 /dev/hda4

(/dev/hda4 es la partición /Download, estoy probando con eso)

Por otro lado he visto que el deco incluye el comando e2fsck, aunque no sé si llevará soporte para ext3. Al pasarlo me sale esto:

e2fsck -n /dev/hda4

He intentado pasar el e2fsck en el disco duro, y "out of memory"

Voy a ver si poniendo una swap grande en un pendrive consigo chequear el disco duro...

 

[hperez]

Con una swap de 512 MB en un pendrive he conseguido chequear el disco duro. Ha tardado una eternidad (más de una hora), y parece que no tiene errores, ya que al final lo único que sale es:

/dev/hdb1: 3120/61063168 files (9.3% non-contiguous), 49783793/122096008 blocks

Para chequear el disco, he usado estas órdenes:

Remontar el disco en modo lectura (aunque sería mejor desmontarlo, pero hay programas usándolo y no me deja):

mount -o remount,ro /dev/hdb1 /DATA/hdb1

Chequear el disco:

e2fsck -n /dev/hdb1

La opción -n le dice que no haga ninguna modificación en el disco.

Y por lo que he leído sí es posible chequear una partición ext3 con fsck.ext2, ya que ext3 es en realidad una partición ext2 con un archivo de journaling.
