Re: [Gluster-users] Brick Goes Offline After server reboot/Or Gluster Container is restarted, on which a gluster node is running
Hi Rifat, I suspect you are hitting https://bugzilla.redhat.com/show_bug.cgi?id=1773856. This bug has been fixed in master and will be backported to release branches soon. Although the bug says, "with volume set operation when a node is down we see the issue", according to the RCA of the bug it can be hit when there is any kind of configuration change in volumes. Hope this helps.

[Gluster-users] Brick Goes Offline After server reboot/Or Gluster Container is restarted, on which a gluster node is running
Hi Gluster Team, I am trying to implment gluster fs in podman containers, which is running except the problems described below. My observations: - The bricks on the server is gong offline when one of the podman container is restarted or the appropriate server is rebooted. - Althoug the status of the bricks are offline, the replication seems to be working, as data will be replicated. - I see that the replicated data will also be replicated on arbiter node, where I was expecting to see only meta data. My configuration. I created glusterfs for replication in 3 nodes on centos7 but in podman containers The containers in the first and second nodes should be normal replication and 3rd node arbiter node. After creation replication and enabling heal processes I can see also that 3rd node is marked as arbiter node. According to description of arbiter, the arbiter node should store only metadata but in my configuration the replicated data will be stored in all bricks including arbiter node. Questions: When rebooting one of the server or restarting one of the glusterfs container the restarted container is not going online until gluster volume is stopped and started again. Is it a solution inbetween to resolve this problem? -why Arbiter node stores all the data, allthough it should only have some metadata to restore the replicated data on other nodes. I would not have problem that replication is done in all three nodes. I just need to know - Can you give me feedback, whether some one experience or similar porblems with glusterfs implemented in podman containers? Here are my configurations: on all containers I have :CentOS Linux release 7.7.1908 glusterfs version 7.3 and systemctl is enabled for glusterd service My gluster volume creation: gluster volume create cgvol1 replica 2 arbiter 1 transport tcp avm1:/cbricks/brick1/data avm2:/cbricks/brick1/data dvm1:/cbricks/brick1/data force gluster peer status excuted on avm2: Number of Peers: 2 Hostname: avm1 Uuid: 5d1dc6a7-8f34-45a3-a7c9-c69c442b66dc State: Peer in Cluster (Connected) Hostname: dvm1 Uuid: 310ffd58-28ab-43f1-88d3-1e381bd46ab3 State: Peer in Cluster (Connected) gluster volume info Volume Name: cgvol1 Type: Replicate Volume ID: da975178-b68f-410c-884c-a7f635e4381a Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: arvm1:/cbricks/brick1/data Brick2: avm2:/cbricks/brick1/data Brick3: devm1:/cbricks/brick1/data (arbiter) Options Reconfigured: cluster.self-heal-daemon: on cluster.entry-self-heal: on cluster.metadata-self-heal: on cluster.data-self-heal: on transport.address-family: inet storage.fips-mode-rchecksum: on nfs.disable: on performance.client-io-threads: off gluster volume status Status of volume: cgvol1 Gluster process TCP Port RDMA Port Online Pid -- Brick avm1:/cbricks/brick1/data 49152 0 Y 516 Brick avm2:/cbricks/brick1/data 49152 0 Y 353 Brick dvm1:/cbricks/brick1/data 49152 0 Y 572 Self-heal Daemon on localhost N/A N/A Y 537 Self-heal Daemon on dvm1 N/A N/A Y 593 Self-heal Daemon on avm2 N/A N/A Y 374 Task Status of Volume cgvol1 -- There are no active volume tasks gluster volume heal cgvol1 info Brick avm1:/cbricks/brick1/data Status: Connected Number of entries: 0 Brick avm2:/cbricks/brick1/data Status: Connected Number of entries: 0 Brick dvm1:/cbricks/brick1/data Status: Connected Number of entries: 0 Best Regards, Rifat Ucal > Jorick Astrego hat am 14.

Re: [Gluster-users] Brick Goes Offline After server reboot.
Hi, It looks like you have a two node setup? Then it's expected as with two nodes you don't have quorum and this can lead to split brains. To have HA, add another node or an arbiter node. https://docs.gluster.org/en/latest/Administrator%20Guide/arbiter-volumes-and-quorum/ You can also modify the quorum but then you shouldn't be too attachted to the data you have on it.
