 Posted: Mon Dec 29, 2008 8:35 pm Post subject: Where is e4defrag? |
 |
|
I was trying out ext4 filesystem with kernel 2.6.28. I successfully converted an old ext3 fs to ext4 and I was searching for e4defrag to test online defragmentation (and to convert all files to use extents).
I have the latest version of e2fsprogs (1.41.3) and still can't find the e4defrag tool that is used to defragment an ext4 fs.
Where can I get it?

That "broken-out" scares me... I think I'll wait patiently to see it in e2fsprogs

Broken-out means each change is in a separate patch instead of one huge patch that contains everything. |

it's really old stuff there..
you could try to build it from kernel.org git. there is more up to date patches for ext4 stuff anyway. |

I do not believe that defrag it went into 2.6.29 although it may be be in 2.6.30. I know it was not in 2.6.28 unless backported.
