Hi Sander,

It should :) https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3/pdf/Administration_Guide/Red_Hat_Storage-3-Administration_Guide-en-US.pdf page 100, is I think a good start. I think this is the most complete documentation. > When I have replicated bricks (replica 2), I also need to do "remove brick > <volume> replica 2 brick1 brick2 …. , right? Yes, you need to remove both replica’s at the same time. > Last but not least, is there any way to tell how long a “remove brick” will > take when it’s moving the data?

Depends on the size of the disk, the number of files and type of file. Network speed is less a issu, then the IO on the disks/brick. To migratie data from one disk to a other (is like self-healing) GlusterFS will do a scan of all files on the disk, which can cause a high IO on the disk. Because you had also some performance issues, when you added some bricks, I will expect the same issue with remove brick. So do this at night if possible.
