Re: [Moosefs-users] Speed-up the server removal process

[Michal B. <mic...@ge...>]

Hi Stas!

 

Have you done restart of the master or only reload? Reload is not enough,
you need to restart it so that the new limits are set.

 

Marking a disk for removal doesn't stop updating the data. But you need to
remember that a table in CGI monitor has two "states" - one with all disks
and the other without disks marked for removal. Both tables are updated on
the fly.

 

 

Regards

-Michal

Hi.

 

I changed the params to recommended ones in FAQ, but the speed still slow.

 

What other values I can try, and what else can be done to increase the
migration speed.

 

Thanks.

change read/write replication parameters. You need to restart master server
process after change in mfsmaster.cfg file.

Hi.

We want to de-commission a server holding 4TB of data, and have set it all
it's disk to remove mode.

The problem is that it's happen too slow, with average read times of 20 - 30
Mbps. Based on this speed, it will take about a week before this server will
be done.

Is there any way to speed-up the process?

Thanks.
