Viewing file system information 4–7

The MDS and OST service states are described in Table 4-3.

Table 4-2 File system states

State Description

started All file system services are running. Client nodes will be able to mount the file system and

perform I/O operations.

recovering All of the services in the file system have been started. However, one or more of the

services are in the recovering state—that is, waiting for all previously connected client

nodes to reconnect. When the file system is in this state, all I/O operations in progress on

client nodes will stall. Attempts by client nodes to mount the file system will also stall. After

some time, the file systems will go to the started state. (For more information on the

recovery process, see Section 3.8.)

not-started The file system has been started but one or more of the file system services is not active. It

is normal for the file system to be in the not-started state during the time that the

start filesystem filesystem_name command is executing. When the file

system is in this state, client nodes cannot mount the file system or perform I/O operations

to the file system.

stopped All of the services in the file system have been stopped. When the file system is in this

state, client nodes cannot mount the file system or perform I/O operations to the file

system. To start the file system, enter the start filesystem filesystem_name

command.

not-stopped The file system services are supposed to be stopped (that is, the stop filesystem

filesystem_name command has been entered), but one or more of the services are

still active. It is normal for the file system to be in the not-stopped state during the time

that the stop filesystem filesystem_name command is executing. When the file

system is in this state, client nodes cannot mount the file system or perform I/O operations

to the file system.

needs-restart The file system services are active. However, a configuration parameter has been

changed, so that the file system configuration data is now out of date. When the file

system is in this state, client nodes may or may not be able to mount the file system and

perform I/O operations to the file system. Stop the file system at your earliest

convenience, and enter the start filesystem filesystem_name command.

When you start the file system, the file system configuration is updated before the file

system services restart.

deleting The delete filesystem filesystem_name command has been entered and is

still in progress, or has failed to complete. When the file system is in this state, client

nodes cannot mount the file system or perform I/O operations to the file system.

Table 4-3 File system service states

State Description

down The server that the file system service was running on has gone to the down state.

Because the server is down, the service is not actually running. Normally, the service will

fail over to the backup server so that the down state will only be seen for a brief period.

However, if the backup server is not running, the service will stay in the down state until

one of the servers in the server pair is rebooted. If the backup server is running, but the

service remains in the down state for a long time, enter the start filesystem

filesystem_name command to try to start the service again.

load-stalled The service was starting and is in the process of loading, but has not completed within a

reasonable time. The service may eventually finish loading and go to the recovering

or running state. If so, there is no need to take any action. However, if the service

remains in the load-stalled state for 15 minutes, it then moves to the load-failed

state.

When a service is in the load-stalled state, other services are blocked from starting

or stopping on the server.

load-failed The service has been in the load-stalled state for at least 15 minutes. The service will

probably not start. You need to reboot the server to recover from this situation.

When a service is in the load-failed state, other services are blocked from starting or

stopping on the server.

recovering The service is started, but the process of reconnecting all previously connected clients has

not finished.
