Come formattare e montare una grande partizione con dimensioni del settore 4K in Freebsd?

Ho un sistema FreeBSD con partizioni sopra e punto di montaggio. La partizione 7 è una partizione non elaborata che sto cercando di formattare con un nuovo file system, ma non sono in grado di farlo. Ho provato i formati di file system ext2 e msdosfs.

Aggiornamento 1: ottengo l'errore seguente durante la formattazione con ext2:

Devo gestire un disco rigido di dimensioni settoriali 4k in modo diverso?

Oggi sono stato in grado di formattare l'unità con msdosfs:

pod0201-wsa02:rtestuser 17] ./newfs_msdos   -F 32 -S 4096 -c 1 -m 0xf8 /dev/da0p7 
newfs_msdos: trim 48 sectors to adjust to a multiple of 63

pod0201-wsa02:rtestuser 19] mkdir raw
pod0201-wsa02:rtestuser 20] cd /

pod0201-wsa02:rtestuser 22] mount -t msdosfs -o large /dev/da0p7 /data/raw
pod0201-wsa02:rtestuser 23]

per favore vedi man gpart&& man newfs. ;)

Per coprire il layout del disco elencato. Quanto segue sarebbe sufficiente

gpart delete -i 7 da0

Supponendo di volere una partizione MSDOS FAT32 con fat32 come etichetta

gpart add -t fat32 -l fat32 -i 7 da0

Ora formattiamo quella sezione / partizione e etichettiamola FAT32 :)

newfs_msdos -F32 -L FAT32 /dev/gpt/fat32

Fatto. Oh, vuoi montarlo?

mount -t msdos /dev/gpt/fat32 /mnt/
