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 !
Ben
