I have an old reiser filesystem which I'm going to convert to Ext3. The problem I have is to determine the proper block- and inode-sizes for this partition.

The partition is 44 GB large and has to hold 3,000,000+ files of sizes between 1 kb and 10kb, how can I figure out the best ratio of inodes and blocksize?

The below is something I tried which seems OK but makes the copying files incredibly slow.

mkfs.ext3 -t ext3 -c -c -b 1024 -i 4096 -I 128 -v -j -O sparse_super,filetype,has_journal /dev/sdb1

Thanks.

Proper way to set permissions on an external disk's ext3 partition

I have a new external disk and just made an ext3 partition on it. I'm wondering what's the best way to set permissions on it (so that it's rw for certain users). I guess I could chmod ... /dev/sdb1 but I was thinking of a more dynamic way (kind of like uid= and gid= options for vfat and such). >>> More
