similar to: LVM and thin snapshots

Hi there! Im new here. Im trying to install Centos 8 on my laptop. I also want to have a contingency plan in case something brakes. My first thoughts were to use LVM. The idea is that i would take multiple snapshots of the system during the day/week and will keep them for a short time. I read RHEL documentation about how lvm works and pretty much understand how to manage the above scenario

Dear Strahil, Thank you very much for pointing me to the RedHat documentation. I wasn't aware of it and it is much more detailed. I will have to read it carefully. Now as I have a single disk (no RAID) based on that documentation I understand that I should use a data alignment value of 256kB.

Hi David, Also consider using the mount option to specify backup server via 'backupvolfile-server=server2:server3' (you can define more but I don't thing replica volumes greater that 3 are usefull (maybe in some special cases). In such way, when the primary is lost, your client can reach a backup one without disruption. P.S.: Client may 'hang' - if the primary server got

Have you checked this page: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/brick_configuration ? The alignment depends on the HW raid stripe unit size. Best Regards,Strahil Nikolov?

Thanks A lot. I will give it a try , once the RPi is here.

Hi David, Gluster supports live rolling upgrade, so there is no need to redeploy at all - but the migration notes should be checked as some features must be disabled first. Also, the gluster client should remount in order to bump the gluster op-version. What kind of workload do you have ? I'm asking as there are predefined (and recommended) settings located at /var/lib/gluster/groups . You

Hi David, It seems that I have misread your quorum options, so just ignore that from my previous e-mail.

First of all thanks for your fast reply. Second. The server im trying to use is https://dav.mailbox.org/caldav I dont think its a problem with my configuration (although i can always be wrong). I suspect a bug in evolution because sometimes it works. Sometimes i manage to create an event sometimes i cant. I started evolution from a terminal and i noticed that when i fail to create an event i

I guess you didn't receive my last e-mail. Use getfattr and identify if the gfid mismatch. If yes, move away the mismatched one. In order a dir to heal, you have to fix all files inside it before it can be healed.

Hello, I am preparing a brick as LVM thin volume for a test slave node using this documentation: https://docs.gluster.org/en/main/Administrator-Guide/formatting-and-mounting-bricks/ but I am confused regarding the right "--dataalignment" option to be used for pvcreate. The documentation mentions the following under point 1: "Create a physical volume(PV) by using the pvcreate

I've touched the directory one level above the directory with the I\O issue as the one above that is the one showing as dirty. It hasn't healed. Should the self heal daemon automatically kick in here? Is there anything else I can do?

Well, you prepare the host for shutdown, right ? So why don't you setup systemd to start the container and shut it down before the bricks ?

Hi Strahil, Yes, we mount the fuse to the physical host and then use bind mount to provide access to the container. The same physical host also runs the gluster server. Therefore, when we stop gluster using 'stop-all-gluster-processes.sh' on the physical host, it kills the fuse mount and impacts containers accessing this volume via bind. Thanks, Anant ________________________________

Perhaps that's because the 3rd node that wasn't accessible from the client before was the arbiter node? It makes sense, as no data is being generated towards

Hello Community, my name is Strahil Nikolov (hunter86_bg) and I would like to update the following wiki page . In section "Create the New Initramfs or Initrd" there should be an additional line for CentOS7: mount --bind /run /mnt/sysimage/run The 'run' directory is needed especially if you need to start the multipathd.service before recreating the initramfs ('/' is on

Hi Anant, Do you use the fuse client in the container ?Wouldn't it be more reasonable to mount the fuse and then use bind mount to provide access to the container ?

Hi Strahil, In our setup, the Gluster brick comes from an iSCSI SAN storage and is then used as a brick on the Gluster server. To extend the brick, we stop the Gluster server, extend the logical volume (LV) on the SAN server, resize it on the host, mount the brick with the extended size, and finally start the Gluster server. Please let me know if this process can be optimized, I will be happy to
