Phenomenon:

recently, a set of chrysanthemum factory object storage has been launched. OceanStor, connect to F5 as an external DNS, cannot be resolved.

Chrysanthemum factory requires external implementation principle of DNS configuration

The storage side is configured, DNS information.

F5 is also configured according to object storage requirements.

Test:

client the ping IP address can be connected.

But the ping domain name cannot be reached.

S3 Browser, not connected.

Solution:

Dig it and find that the return is wrong,

Through many experts from Huawei and the communication of F5 engineers seems to have been encountered in other bureaus, XWYH. Finally, it is suspected that F5 should enable the "recursive" mode. Currently, F5 enables the "iterative" mode by default.

After enabling, test:

S3 Broswer can also log in normally.

S3 Broswer can also log in normally.

Note: enabled recursive mode is effective and the problem is solved.

Summary: next time, you will encounter object storage docking when you perform domain name resolution on F5, remember to enable the recursion".
