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) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /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
