[Gluster-devel] [Gluster-users] Replica 3 - how to replace failed node (peer)

[David Spisla]

Hello Martin,

look here:
https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.4/pdf/administration_guide/Red_Hat_Gluster_Storage-3.4-Administration_Guide-en-US.pdf
on page 324. There is a manual how to replace a brick in case of a hardware
failure

Regards
David Spisla
