Large directories in ext3?

Large directories in ext3?

Hi there,

I 'm using RHEL3 WS on a dual-Opteron box, and I 'm in the middle of
trying to migrate a few terabytes of data from our old SuSE XFS filesystems.

I 'm running into a wall, though, with ext3 's directory limits.
Apparently, I can only have 32000 entries in a single directory?

[root@(protected) 3]# mkdir test
mkdir: cannot create directory `test ': Too many links

[root@(protected) 3]# ls -lar | wc -l
32001

Is this correct? Is there a way around it without completely
re-structuring my data? (I need ~100,000 entries per directory)

Also, does RH 's kernel support htrees in ext3 for large directories yet?

Thanks,

Don
