Actually, it is the converse - only new (and specially formatted) fs with larger inodes will format with larger inodes and store the EA in the inode for improved performance. Otherwise there is a single fs block for all EAs on a file. If you need a small amount of extra EA space (e.g. 128 or 384 bytes) and you control the environment then formatting the filesystem with "mke2fs -j -I 512" can give you some more space, but not a huge amount. -I == total inode size; includes 128 bytes for inode; can be up to 4096 bytes > Is there any way > to allow for more space for extended attributes in an ext3 partition? Not currently. We did some work to allow large EAs to be stored in a separate inode, but that doesn't help if you have lots of small EAs. > I know that xfs has no limits on extended attributes, but I have > several orthogonal reasons for sticking with ext3. Hmm, I thought XFS had a 64kB EA limit? What is it you are trying to do? There are often better solutions than storing a lot of data in EAs.
