Re: [Gluster-users] Arbiter node in slow network
As Alan mentioned latency is more important. Also consider using an SSD for all arbiter bricks and set maxpct (man 8 mkfs.xfs) to a high level (I prefer to use '90').

Re: [Gluster-users] [EXT] Re: [Glusterusers] Arbiter node in slow network
sorry for the late reply. We use exactly that setup 10G - 10G - 1G (arbiter on a little desktop box) All drives are SSDs Because the arbiter only sees the metadata , 1GB is more than enough On a VM host cluster the charts the peak activity for the arbiter rarely exceeds a couple Mb/s during normal ops and even when healing after host maintenance its less than 100Mb/s -wk On 12/31/2022 12:43 AM, Alan Orth wrote: Hi Filipe, I think it would probably be fine.
