[Moosefs-users] How to speed up mfsmaster loading a big metadata ?

[<wei...@10...>]

Hi MFS users,

First, I was installed two meta server(master & slave) and use DRBD and Heartbeat to
make it can redundantly. A few year later, my metadata file is too big to load quickly.

Now, I have a big metadata (about 40GB) on DRBD disk. I has been try to put metadata
on SSD Disk (Intel 520 Serial), but it was still not fast enough when I got a failover.

In my production:
Master crash, and failover to slave need 3 ~ 5 mins. Because mfsmaster load metadata
to ram slowly.

Does anyone has a good idea to solve it ? Please give me directions, thanks.




Best Regards.
