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

E2fsprogs does require some patches.  Whamcloud's site has patched versions available for download:

Hello again! I posted here earlier about my attempts at building Lustre 
with Nix. There was another issue I was struggling with, related to 
e2fsprogs, that I thought I should ask here if I was supposed to patch 
it too?




My mkfs.lustre (ldiskfs) is failing with mke2fs complaining about an 
"incompatible option set". Specifically it's complaining about the 
option `dirdata`. 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.




Do I have to patch e2fsprogs?




Do tell me if I'm being too noisy or if there's a better channel for 
this sort of questions. I actually have a few more, should I ask each in 
a separate thread or should I aggregate all under one SUBJECT?




Thanks
