Truecrypt:non monta

[Meskalamdug]

device-mapper: create ioctl failed: Dispositivo o risorsa occupata
Command failed

Ovviamente...

A)Non c'è alcun disco montato da truecrypt

B)Lsof|grep dmesetup truecrypt mapper non
restituisce nulla..

Qualcuno sa come risolvere?
Grazie

[neongen]

se non ricordo male servono i moduli crypto XTS e LRW nel kernel

[Meskalamdug]

Ci sono

[neongen]

e dm_crypt?
(scusa ma sto guardando il diff tra il vecchio config e quello di adesso per ricordarmi quali moduli ho attivato per risolvere lo stesso problema)

edit:ma il device-mapper lo hai messo?

[Meskalamdug]

Ho risolto..rimuovendo
truecrypt,userò un
programma simile(c'è ne sono
a decine)

Riesumo questa conversazione perchè ho un errore simile su Slackware64 13.1.

Ecco l'errore:

Codice: Seleziona tutto

/proc/misc: No entry for device-mapper found
Is device-mapper driver missing from kernel?
Failure to communicate with kernel device-mapper driver.
Command failed

Penso che dipenda dalla mancanza di qualche modulo del kernel..

Attualmente ho questi:

Sapreste darmi una mano?

P.S. Sto usando il .config generic modificato.

[Ansa89]

Secondo me non hai caricato il modulo del device-mapper, oppure non ce l'hai proprio.
Prova a postare l'output di

Non hai compilato il modulo nel kernel.

Non hai compilato il modulo nel kernel.

Ho capito,
ma qual è il modulo che manca?
Grazie mille!

[Ansa89]

Il nome del modulo è "dm-mod" (se non ricordo male) e il simbolo dovrebbe essere "CONFIG_BLK_DEV_DM".

[Ansa89]

Mi sembra ti manchi ancora "CONFIG_BLK_DEV_DM".
Nella configurazione del kernel devi andare in Device Drivers->Multiple devices driver support (RAID and LVM)->Device mapper support.

vielen dank!
L'avevo disabilitato..

Bitte sehr.
