HP StorageWorks Scalable File Share - Manual (Page 66)

Viewing system information 4–10
Size
The size of the LUN, in gigabytes.
Used
For the MDS service: the percentage of the total number of files (shown in the
Files
field) used by existing files (for example, a value of 30% indicates that
another 60% of the total number of files can be created).
For OST services: the percentage of the total space used by files stored in the
OST service (for example, a value of 80% indicates that the OST LUN is quite
full).
Service State
The state of the MDS or OST service. See Table 4-3 for a description of the
possible server states.
Running on
The server where the service is currently running. If an MDS or OST service is
not running on its preferred server, the server is highlighted with an
exclamation mark (
!
), and the following message is displayed by the
show
filesystem filesystem_name
command:
(servers marked ! are not preferred server)
If the service is stopped, the name of the preferred server is shown. The name
of the server is highlighted with an asterisk (
*
) and the following message is
displayed:
(servers marked * are preferred server; service is not
running)
The output from the
show filesystem data
command above shows that there are two errors in the file
system storage configuration:
• In the server pair of
south3
and
south4
, the
south3
server is overloaded, because three OST
LUNs have been preferred to this server and only one has been preferred to the
south4
server. This
is the result of an error in the way the preferred server for each OST LUN was specified when the file
system was configured. For more information on configuring file systems, see Chapter 5.
• Array number 3 is presented through only one controller. This indicates that there is a problem with
the EVA4000 array; one of the controllers may have failed.
4.3 Viewing OST service information
The
show ost
command lists the servers that serve each OST service in the system, as well as the file system
that each OST service is used by.
To view the information on all OST services in the system, enter the
show ost
command, as shown in the
following example:
sfs> show ost
