Hi,

I want to know how many parallel  read requests for one volume at the same time? or how many parallel read requests for one replication volume at the same time?

In our afs system, there are about one hundred people to read a volume parallelly, and each people will issus about 500 read requests. I found the afs client's /var/log/message file often appear  some error information, such as "volume 536871264 is busy or server is down, recheck ".

so, I want to know its reason.

Thank you!

With best regards !
 
Yours sincerely

Dong xu
