converting lzo compression to zlib compression?
I have a btrfs filesystem mounted with "compress=lzo" now.
I'd like to see how much space would I save by converting it to zlib.
Would it be possible to convert lzo compression to zlib compression with the following:
- mount the filesystem with "compress=zlib"
- run balance
- when balance finishes, the data would be compressed with zlib
Would this work as above, or do I have to copy the data out and back to convert from lzo compression to zlib compression?

Hi,
I'm afraid the above won't work, cause balance is not aware of the compression so that it won't decompress the data.
thanks,
