Subject: comm setfattr: corrupted xattr entries on 'clean' filesystem


Not sure this is the best place for this, but it was
suggest on #linuxfs to report the problem here ...

I have an (older) ext3 filesystem where 'some' files
are unable to accept any extended attributes (xattrs).

 # setfattr -n user.x -v y some-file

... results in ...

 setfattr: some-file: Structure needs cleaning

... and the kernel reports ...

kernel: EXT4-fs error (device md2): ext4_xattr_set_entry:1607: inode #2084096: comm setfattr: corrupted xattr entries

... kernel is not the latest (4.19.84), but e2fsck is ...

e2fsck 1.45.5 (07-Jan-2020)

/dev/md2: 6594874/9538640 files (2.7% non-contiguous), 3887814750/3907018432 blocks

Any suggestions how to 'clean my structures' would
be appreciated!

Thanks in advance,
Herbert
