Re: [lustre-devel] mke2fs supported features: dirdata

Dear user,

Yes, you also need to build a patched e2fsprogs.
This is outlined in the Whamcloud hosted instructions and I recently wrote instructions for Rocky 8.10 & 9.4 (hosted on Github), though kernel release numbers changed since...

The Whamcloud Wiki is here: https://wiki.whamcloud.com/display/PUB/Building+Lustre+from+Source
My own instructions are here: https://github.com/DetlevCM/lustre-build-instructions

Kind regards
Detlev

Looking at e2fsprogs' sources, `EXT4_FEATURE_INCOMPAT_DIRDATA` isn't listed in `ok_features` in `misc/mke2fs.c`. Even if I add it there, mke2fs fails later at `ext2fs_initialize`. I was surprised not to find any error reports in jira concerning dirdata specifically (there were similar errors reported for e.g. large_dir), surely I must be doing something wrong.
