After reading several articles about migrating existing Ext3 filesystems to Ext4, I decided to try it with my one drive.
Before You start:
- make sure You have the latest OE2.0 DMM experimental image!
- it can take several hours to complete the migration!
Open a telnet connection:
# Stop Enigma2
# Display mounted disks
# Unmount the disk
# List available devices
# Convert the filesystem # The first step will run fairly fast
tune2fs -O extents,uninit_bg,dir_index /dev/sda1
# Repair it
# The second step will take a while, in my case for 1TB about 1 hour
fsck.ext4 -yfD /dev/sda1
