OPTIONS
-------
-d::
Disable data checksum.
-i::
-d|--no-datasum::
Disable data checksum calculations and set NODATASUM file flag. This can speed
up the conversion.
-i|--no-xattr::
Ignore xattrs and ACLs.
-n::
Disable packing of small files.
-N <SIZE>::
-n|--no-inline::
Disable inlining of small files to metadata blocks.
-N|--nodesize <SIZE>::
Set filesystem nodesize, the tree block size in which btrfs stores data.
The default value is 16KB (16384) or the page size, whichever is bigger.
Must be a multiple of the sectorsize, but not larger than 65536.
-r::
-r|--rollback::
Roll back to ext2fs.
-l <LABEL>::
-l|--label <LABEL>::
set filesystem label during conversion.
-L::
-L|--copy-label::
use label from the converted filesystem.
-p::
-p|--progress::
Show progress of conversion, on by default.
--no-progress::
Disable detailed progress and show only the main phases of conversion.
