wherein fn(α): function defined as a number of error generation(α) in a hardware of the SCM client unit at an n-th transmission cycle, and
wherein g1˜n(β): function defined as a number of error generation(β) in the distributed file system of the SCM client unit from a first transmission cycle to the n-th transmission cycle.

### Claim 6 (depends on 3)

The distributed file system processing apparatus of claim 3, wherein the SCM server unit continually updates the generated setting information until a corresponding distributed file system restarts to set the corresponding distributed file system as a setting item of a most recent version of a setting item at the restart point.

### Claim 7 (depends on 6)

The distributed file system processing apparatus of claim 6, wherein the SCM client unit requests, to the SCM server unit, setting information generated based on setting item of previous version in the setting environment database when the setting failed.

### Claim 8 (depends on 7)

The distributed file system processing apparatus of claim 7, wherein the SCM client unit repeats the request to set the corresponding distributed file system as setting information generated based on a corresponding version setting item until the setting succeeds.

### Claim 9 (depends on 8)

The distributed file system processing apparatus of claim 8, wherein the SCM server unit stores a current version of the corresponding distributed file system in the setting environment database when the setting succeeds.

### Claim 10 (depends on 2)

The distributed file system processing apparatus of claim 2, wherein the SCM client unit tests a performance of the distributed file system to request a properties item of the best previous version in the setting item history.

### Claim 11 (depends on 10)

The distributed file system processing apparatus of claim 10, wherein the SCM server unit determines whether a properties item of the best previous version is applied to other SCM client unit when the request of the previous version received.

### Claim 12 (depends on 1)

The distributed file system processing apparatus of claim 1, wherein the SCM server unit compulsorily restarts the distributed file system to apply to a most recent version setting item when the SCM client unit is idle during a specific time.

### Claim 13

A distributed file system processing method performed by a distributed file system processing apparatus, the apparatus including at least one service configuration and management (SCM) client unit, a SCM agent unit and a SCM server unit, the method comprising:
managing, through the SCM server unit, each setting item in the distributed file system of SCM client unit per version through a setting environment database, and generating each of a most recent version setting item in the setting environment database according to the specific regulation; and
setting, through the SCM agent unit, a distributed file system in the SCM client unit to provide the generating setting information from the SCM server unit to the SCM client unit.

### Claim 14 (depends on 13)

The distributed file system processing method of claim 13, further comprising managing a setting item of the distributed file system per version through the setting environment database to detect a change in each of the setting item to update a setting item history per the setting item.

### Claim 15 (depends on 10)

The distributed file system processing method of claim 10, further comprising generating the setting information according to the specific regulation to restore the corresponding setting item to a previous version through the setting item history when an error occurs in the distributed file system of a specific SCM client unit.

### Claim 16 (depends on 15)

The distributed file system processing method of claim 15, further comprising setting a distributed file system in the specific SCM client unit to transmit at regular intervals whether the specific SCM client unit normally operates to the SCM sever unit.

### Claim 17 (depends on 16)
