Objet : RE: [HPDD-discuss] Data lost on OST
No, I plan to use 3 OSS servers, each with 1 OST. In a first time I deployed archives-mds
(MDT000) and archives-oss3 (OST002). In second time I deployed archives-oss2 (OST001). I
never use the third server archives-oss1 (OST000). OST000 doesn't exist.
I do a test just now ...
I copied some data to my lustre volume, about 106 GO.
I have no error with the copy operation. But je problem is the same. I don't have all
data. I found data on OST002, but nothing on OST001
