LiveCD System recovery - Mounting LVM?
Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

can't boot after volume rename
Get a CentOS Install media , boot from it and select troubleshoot.Then mount your root LV, boot lv , /proc/, /sys, /dev & /run (last 4 with "bind" mount option).Then chroot into the root LV's mount point and then change grub menu and run "dracut -f --regenerate-all" last step is to reboot and test.

Unable to get dummy interfaces to persist across reboots in CentOS 8
Have you tried to use NetworkManager ? After all ,anything network related should be done by it. [root at system ~]# nmcli connection add con-name dummy0 ifname dummy0 type dummy ?

GFS performance under heavy traffic
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

File\Directory not healing
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.

File\Directory not healing
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?

Wiki update
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

Graceful shutdown doesn't stop all Gluster processes
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 ?

Unable to get dummy interfaces to persist across reboots in CentOS 8
Requirement is a very strong word , but you should consider using it and here is a short demo why: - By default, RHEL uses NetworkManager to configure and manage network connections, and the /usr/sbin/ifup and /usr/sbin/ifdown scripts use NetworkManager to process ifcfg files in the /etc/sysconfig/network-scripts/ directory. [root at system ~]# ls -l /usr/sbin/ifup lrwxrwxrwx. 1 root root 22 21

can't mount an LVM volume inCentos 5.10
I have a degraded raid array (originally raid-10, now only two drives) that contains an LVM volume. I can see in the appended text that the Xen domains are there but I don't see how to mount them. No doubt this is just ignorance on my part but I wonder if anyone would care to direct me? I want to be able to retrieve dom-0 and one of the dom-Us to do data recovery, the others are of

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 ?

Graceful shutdown doesn't stop all Gluster processes
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 ________________________________

Unable to get dummy interfaces to persist across reboots in CentOS 8
No. Network Manager is always disabled on our builds since at least Cent5 days. The network stack has always been able to be managed properly without relying on Network Manager. Is that now an absolute requirement? It never has been prior.

Graceful shutdown doesn't stop all Gluster processes
Okay, I understand. Yes, it would be beneficial to include an option for skipping the client processes. This way, we could utilize the 'stop-all-gluster-processes.sh' script with that option to stop the gluster server process while retaining the fuse mounts. ________________________________ From: Aravinda <aravinda at kadalu.tech> Sent: 16 February 2024 12:36 PM To: Anant Saraswat

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

Graceful shutdown doesn't stop all Gluster processes
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

Geo replication procedure for DR
Dear Strahil, Thank you for the detailed command. So once you want to switch all traffic to the DR site in case of disaster one should first disable the read-only setting on the secondary volume on the slave site. What happens after when the master site is back online? What's the procedure there? I had the following question in my previous mail in this regard: "And once the primary

How to find out data alignment for LVM thin volume brick
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.

Anyone have any ideas? It's rather annoying that I can't get these to persist across reboots without using some kind of helper script.
