Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.
> Due to some reasons, the secondary will be down for 1 month, will it have any poor impact on primary when the secondary is down and after the secondary is up? As I understand it, the only impact will be a larger-than-normal resync when you bring the secondary back up. I don't believe running without the secondary will slow down the primary, as it just tracks the changes in its bitmap. So the real issue comes down to the size of your filesystem and how much of it will be written to during the downtime. -Ben
