Re: [Gluster-users] How Does Gluster Failover

With a replica volume the client connects and writes to all the replicas directly. For reads, when a filename is looked up the client checks with all the replicas and, if the file is healthy, opens a read connection to the first replica to respond (by default). If a server is shut down, the cl

By that same token, you can also use a hostname with multiple A records and glusterd will use those for failover to retrieve the vol file. On 8/31/22 8:32 AM, Joe Julian wrote: Kind-of. That just tells the client what other nodes it can use to retrieve that volume configuration. It's

Big raid isn't great as bricks. If the array does fail, the larger brick means much longer heal times. My main question I ask when evaluating storage solutions is, "what happens when it fails?" With ceph, if the placement database is corrupted, all your data is lost (happened to my employer, o

Re: [Gluster-users] question about list directory missing files or hang

I'm betting that your bricks are formatted ext4. If they are, you have a bug due to a recent structure change in ext4. If that is the problem, you can downgrade your kernel to before they backported the change (not sure which version that is though), or reformat your bricks xfs. On 08/14/2012

It's only "far from good" for certain use cases, not all. I'm actually quite pleased that GlusterFS emphasizes C & P over A and none of my users complain ( I use raw images for 14 kvm vms on one of my GlusterFS volumes ). Those VMs mount GlusterFS volumes for their application data. Very little
