[Gluster-users] Recovery when 2 of 3 servers goes down!
How there
I have 3 servers with gluster 7 installed and setting up with replica 3 and
arbiter 1.
Here's the commands I used:
- First create a simple volume with one server:
gluster volume create VMS proxmox01:/DATA/vms
- Then add the second one
gluster peer probe proxmox02
gluster volume add-brick VMS replica 2 proxmox02:/DATA/vms
- And finally and the third:
gluster peer probe proxmox03
gluster volume add-brick VMS replica 3 arbiter 1 proxmox03:/DATA/vms
But then I decide to test the environment and bring proxmox02 and proxmox03
down and get Transport endpoint is not connected after a few seconds.
Is there a way to keep one server up if 2 goes down?

[Gluster-users] Recovery when 2 of 3 servers goes down!
I had the same requirements (except with 4 servers and no arbiter), and this was the solution: gluster v set VMS cluster.quorum-count 1 gluster v set VMS cluster.quorum-type fixed Sincerely, Artem -- Founder, Android Police <http://www.androidpolice.com>, APK Mirror <http://www.apkmirror.com/>, Illogical Robot LLC beerpla.net | @ArtemR <http://twitter.com/ArtemR> On Fri, Jul 17, 2020 at 6:50 AM Gilberto Nunes <gilberto.nunes32 at gmail.com> wrote:> How there > > I have 3 servers with gluster 7 installed and setting up with replica 3 > and arbiter 1. > Here's the commands I used: > - First create a simple volume with one server: > gluster volume create VMS proxmox01:/DATA/vms > - Then add the second one > gluster peer probe proxmox02 > gluster volume add-brick VMS replica 2 proxmox02:/DATA/vms > - And finally and the third: > gluster peer probe proxmox03 > gluster volume add-brick VMS replica 3 arbiter 1 proxmox03:/DATA/vms > > But then I decide to test the environment and bring proxmox02 and > proxmox03 down and get Transport endpoint is not connected after a few > seconds. > Is there a way to keep one server up if 2 goes down? > gluster vol info > > Volume Name: VMS > Type: Replicate > Volume ID: 64735da4-8671-4c5e-b832-d15f5c03e9f0 > Status: Started > Snapshot Count: 0 > Number of Bricks: 1 x (2 + 1) = 3 > Transport-type: tcp > Bricks: > Brick1: proxmox01:/DATA/vms > Brick2: proxmox02:/DATA/vms > Brick3: proxmox03:/DATA/vms (arbiter) > Options Reconfigured: > nfs.disable: on > storage.fips-mode-rchecksum: on > transport.address-family: inet > performance.client-io-threads: off > cluster.self-heal-daemon: enable > cluster.quorum-reads: false > cluster.quorum-count: 1 > > gluster vol status > Status of volume: VMS > Gluster process TCP Port RDMA Port Online > Pid > ------------------------------------------------------------------------------ > > Brick proxmox01:/DATA/vms 49152 0 Y > 1526 > Self-heal Daemon on localhost N/A N/A Y > 1537 > > Task Status of Volume VMS > ------------------------------------------------------------------------------ > > There are no active volume tasks > > > Thanks a lot > > > --- > Gilberto Nunes Ferreira > > (47) 3025-5907 > (47) 99676-7530 - Whatsapp / Telegram > > Skype: gilberto.nunes36 > > > > ________ > > > > Community Meeting Calendar: > > Schedule - > Every 2nd and 4th Tuesday at 14:30 IST / 09:00 UTC > Bridge: https://bluejeans.com/441850968 > > Gluster-users mailing list > Gluster-users at gluster.org > https://lists.gluster.org/mailman/listinfo/gluster-users >-------------- next part -------------- An HTML attachment was scrubbed...
