= Remove a dir which can’t be deleted normally (problems in lost+found) =

When trying to delete a dir:
<pre>jail14 /usr/home/user# rm /mnt/data2/69.55.228.247-col01550-DIR/lost+found/* 
 override rw-------  4294967295/255 uappnd,uchg,opaque,uunlnk for /mnt/data2/69.55.228.247-col01550-D 
 IR/lost+found/#336682? y 
 rm: /mnt/data2/69.55.228.247-col01550-DIR/lost+found/#336682: Operation not permitted</pre> 

Which leads to:
 <pre>Fatal trap 12: page fault while in kernel mode 
 cpuid = 2; apic id = 06

Do:

now, <tt>fsck</tt> (no -y)

(salvage freed space) 

OR, forget the above and just:

 tar -c --exclude lost+found -pPz -f /mnt/data1/temp/760.tgz * 
 cd [new dir]
 tar -xpPBzf /mnt/data1/temp/760.tgz
