ext4 extending extended attributes

Does it possible to make ext4 file system store extended file attributes of more than 4 KB?

It seems that the ea_inode feature, documented in the ext4 man page, allows extended attributes that are larger than a filesystem block. You should be able to set it with tune2fs.

Note that you can tune a filesystem, but you can't tuna fish (reference).

Thank you very much, will this feature for the file system remain forever? I have never used tune2fs before.

While I have no guarantee, it would be extremely improbable that an existing filesystem feature disappears. Perhaps it will be discontinued in ext5. but it will certainly remain in ext4.

Just be aware that the default FS for RHEL7 & RHEL 8 is xfs, so you'll have to specify ext4 at build time.
