Hi,
osd.0 and osd.2 size 500 MB, osd.1 and osd.3 size 1 TB. I known I need
to set up weight correctly, but it was a test only.
You need to set up the weights correctly, even though it is only a test.
My question: this is the correct works?
Yes.
If I have 1000 OSD and only one
is reach full, the whole cluster go to read-only?
No, that is not the case.
Per my understanding the files will be mapped to objects in pgs, that
are again mapped to individual osds. If you want to write to a pg that
is mapped to an osd that is full, then that write cannot succeed.
However the whole cluster does not go "read-only", only the the pgs that
are actually mapped to the osds that are full.
