AFR + Unify problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi ! 

 

I wanna build one large storage pool with redundancy, in my test
environment, it consist of two controllers and four storage nodes.

 

Controller 1 and Controller2 

Storage nodes 501 502 503 504

Afr1 501 502

Afr2 503 504

Unify Afr1 and Afr2

 

But i got some problem when I did failover testing.

 

Case1:

Create file1 from controller1 > file1 locate in 501 502 > down 501 > modify
file1 > up 501 

both controllers also read old data of file1, even run self-heal script and
the content of file1 have ^@^@^@^@^@^@^@ at the bottom

 

Case2:

File2 locate in 503 504 > down 503 > delete file2 > file2 locate in 501 502
> up 503

One controller can read new data of file2 and one read old data of file2 ,
and old file2 still locate in 503 even run self-heal script already

 

Would you tell me how to solve above issue? Or any wrong setting for my
configuration?

I afr all namespace for all of storage nodes, is it possible? Because I read
many doc from yours also have not afr the namespace or just afr two
namespace only.

 

Thank you so much !
