sylla:~# xfs_io -r -c "chattr -i" /lost+found/3912672557
/lost+found/3912672557: No such file or directory
Strange. This implies that lookup can't find inode # 3912672557.
We know it is there...
How many other files in the directory? Can you get the inode number
for the lost+found directory and dump that with xfs_db (as per above)?
Also, what happens if you "touch /lost+found/unix.7.gz" and try again?
Cheers,
Dave.
Being a symbolic link, xfs_io follows them rather than operates on
them directory.
This will probably require xfs_db magic with the unmounted filesystem:
# xfs_db -x -c "inode 3912672557" -c "write core.immutable 0" <device>
