looks to me like readdir() only reads the direct blocks, but that
doesn't seem right since 4090*264 ~= 1mb.

The problem applies also for Iru's version on sources...

sounds like you have a 9atom-compiled libc.a, but then updated
/386/include/u.h from the distribution overwriting the definition
of Rune.  (changing it from uint to ushort).  you either need to
recompile all your libraries, or put u.h back the way it was.

4090 seems to be the maximum number of files that can reside in an
ext2srv served directory:

 ext2srv
mount -c /srv/ext2 /n/linux /dev/sdE4/linux
cd /n/linux/x

term% for(i in`{seq 1 5000})  touch $i
touch: 4091: cannot create: '4091' no space on device
rm [0-9]*
ls
cp ../y/foo .
ls -l
--rw------- M 48 1000 1000 1950 Oct 19 12:14 foo
term%

term% for(i in`{seq 1 5000})  cp foo $i
cp: can't create 4090: '4090' no space on device

===
I forgot to say that I'm using the ext2srv version from Plan
distribution, not the Iruata's from contrib/iru;
compiling iru's ext2srv gives error:
term% mk
8c -FTVw xfssrv.c
8c -FTVw xfile.c
8c -FTVw ext2fs.c
8c -FTVw ext2subs.c

hi,

the problem reported before (2011) with ext2srv still persists, here
is some output:

## On Plan9 native:
term% du -a /n/linux/dir | wc -l
   1758
term% ls -l /n/linux/dir | wc -l
   1757

## On Linux:
% 9 du -a /dir | wc -l
12925
% 9 ls -l /dir | wc -l
12924
% 9 du -s /dir
951227	/dir


thanks,
++pac
