hi,
I have a case,
1. SATA disk + buffered write
2. one node with N disks, and the first disk is meta disk, and the left 1.N
is data disk
3. I will write data in disk 1-N, and record the chunk file length in meta
disk (disk0).
in such case, can I safely set data=writeback without any possible problem,
maybe include data corrupt, slow recovery when node restart, ... ?
thanks very much.
