hi,all
my question is from my test.
let's take a example. object1(4MB)--> pg 0.1 --> osd 1,2,3,p1
when client is writing object1, during the write , osd1 is down. let suppose
2MB is writed.
1.
when the connection to osd1 is down, what does client do? ask monitor for
new osdmap? or only the pg map?
2.
now client gets a newer map , continues the write , the primary osd should be
osd2. the rest 2MB is writed out.
now what does ceph do to integrate the two part data? and to promise that
replicas is enough?
3.
where is the code. Be sure to tell me where the code is。
it is a very difficult question.
Thanks so much
