Her ne kadar hata "Err: 5009-filecopy işlemi başarısız oldu (nfs: I/O error)" ifadesi, Data Domain sorunları için genel bir hatadır. Temel nedeni bulmak için Data Domain üzerinde daha fazla araştırma yapılması gerekmektedir.

Bu örnekte sorun, şifrelemenin kaynak ve hedef Data Domain'lerde aynı şekilde yapılandırılmamış olmasından kaynaklanmaktadır.

Günlükte aşağıdaki olaylar bildirildi:

02/26 22:01:51.161 (tid 0x7fa4fa49ffe0): filecopy ctx 541 dst DD-6800-2.company.com: ASSOC failed: Encrypted replication incompatible between source and destination (5342) (5342)

Bu, kaynak ve hedef (veya hedef) Data Domains'deki şifreleme ayarı kontrol edilerek doğrulanmıştır:

Source:

ddboost file-replication option show encryption

Encryption for file-replication is: disabled 

Hedef:

ddboost file-replication option show encryption

Encryption for file-replication is: enabled 

1. Şifrelemenin her iki Data Domain'de de etkinleştirilmesi veya devre dışı bırakılması gerektiğini doğrulayın.

2. Yanlış şifreleme yapılandırmasına sahip hedefte oturum açın.

3. Şifrelemeyi kontrol edin, ayarlayın ve doğrulayın:

Şifrelemeyi etkinleştirmek için:

ddboost file-replication option show encryption

Encryption for file-replication is: disabled
Authentication-mode is: anonymous

ddboost file-replication option set encryption enabled

Encryption for file-replication set to "enabled".

ddboost file-replication option show encryption

Encryption for file-replication is: enabled
Authentication-mode is: anonymous

Şifrelemeyi devre dışı bırakmak için:

ddboost file-replication option show encryption

Encryption for file-replication is: enabled
Authentication-mode is: anonymous

ddboost file-replication option set encryption disabled

Encryption for file-replication set to "disabled".

ddboost file-replication option show encryption

Encryption for file-replication is: disabled
Authentication-mode is: anonymous

4. Şifrelemenin etkinleştirildiği veya şifrelemenin devre dışı bırakıldığı Data Domain'de ddboost'u yeniden başlatın.

ddboost status

DD Boost status: enabled

ddboost disable

The 'ddboost disable' command aborts running DD Boost operations.
        Are you sure? (yes|no) [no]: y
ok, proceeding.

DD Boost disabled.

ddboost enable 

DD Boost enabled.

ddboost status 

DD Boost status: enabled

5. Çoğaltmayı yeniden çalıştırın.
