Conversion Ext2 vers Ext3 :<\/strong><\/p>\n

sudo tune2fs -j \/dev\/sda1<\/code><\/p>\n

Conversion Ext2 vers Ext4 :<\/strong><\/p>\n

sudo tune2fs -O extents,uninit_bg,dir_index,has_journal \/dev\/sda1<\/code><\/p>\n

Conversion Ext3 vers Ext4 :<\/strong><\/p>\n

sudo tune2fs -O extents,uninit_bg,dir_index \/dev\/sda1<\/code><\/p>\n

Etape 4 : V\u00e9rifier la partition<\/strong><\/p>\n

sudo e2fsck -pf \/dev\/sda1<\/code><\/p>\n
