An error message may be 
generated if you have a file system 
configured with one or more LUNs 
that are "short-labeled", that is, 
LUNs that have a raw capacity 
greater than 4294967295 sectors, 
but have been labeled with a 
reduced capacity of 4294967295 
sectors (the maximum number of 
sectors supported in a LUN by 
StorNext 2.6) and one or more files 
are trespassing on the restricted 
area of the LUN.

1 On the metadata 

controller node, run the 

cvfsck -t <fsname>

 

command to list the 
names of files or 
directories allocated in 
the restricted area 
('trespassing' files).

2 On a client machine -- 

which should be same 
type of system (same 
OS) as the client 
machine that created the 
data originally -- move 
each of the listed files to 
non-restricted areas of 
the file system:

• For each trespassing file, 

use the 

snfsdefrag

 

command to create a 
new copy of the file. For 
example: for a file called /

stornext/snfs1/

xxx, 

type:        

snfsdefrag -m 0 /

stornext/snfs1/xxx

•  If any trespassing 

directories are listed, 
please contact ADIC 
technical support for 
instructions to correct the 
problem.

When a fullstop of the file system 
services is initiated, the 

/etc/

init.d/cvfs fullstop

 script 

executes a 

fuser -km $FSNAME

, 

that kills all processes with open 
inodes in the file system.
