Hello, As we know, libvirt sanlock support file type storage. I wonder *if it supports network storage.* I tried *iSCSI*, but found it didn't generate any resource file: Version: *qemu-2.10 libvirt-3.9 sanlock-3.5* 1. Set configuration: qemu.conf: *lock_manager = "sanlock"* qemu-sanlock.conf: *auto_disk_leases = 1disk_lease_dir = "/var/lib/libvirt/sanlock"host_id =

Hi list, I would like to ask a clarification about how locking works. My test system is CentOS 7.7 with libvirt-4.5.0-23.el7_7.1.x86_64 Is was understanding that, by default, libvirt does not use any locks. From here [1]: "The out of the box configuration, however, currently uses the nop lock manager plugin". As "lock_manager" is commented in my qemu.conf file, I was

Hello list, In short: I am experiencing a problem where trying to start a VM which is allready running on a different libvirt host. Starting it fails, thanks to sanlock, but the disk dies on the original hypervisor and the vms filesystem is rendered read-only. Long version: i have the following setup: Two machines (H1 and H2) using CentOS 6.2 with the packages:

Hi Jeremy, thanks for the tip but ...(there's always a but) if I do this (increase MAX_OPEN_FILES to 1024), I get an error in log.smb: Can't create or use IPC area. Error was File exists I'm using FAST_SHARE_MODES to compile samba. Does this take up too much space or is there something else wrong?

Hi, I'm trying to put in place a KVM cluster (using clvm and gfs2), but I'm running into some issues with either sanlock or virtlockd. All virtual machines are handled via the cluster (in /etc/cluser/cluster.conf) but I want some kind of locking to be in place as extra security measurement.

Hello, I configured libvirtd with the sanlock lock manager plugin: # rpm -qa | egrep "libvirt-0|sanlock-[01]" libvirt-lock-sanlock-0.9.4-23.el6_2.4.x86_64 sanlock-1.8-2.el6.x86_64 libvirt-0.9.4-23.el6_2.4.x86_64 # egrep -v "^#|^$" /etc/libvirt/qemu-sanlock.conf auto_disk_leases = 1 disk_lease_dir = "/var/lib/libvirt/sanlock" host_id = 4 # mount | grep sanlock

Hello, I wonder what the "open error -1" / "release open_disk error" messages in sanlock.log actually mean. I saw these messages in the log on a KVM host that rebooted, and after running "/usr/sbin/virt-sanlock-cleanup" on that host. The resources where disks from 2 guests running on another KVM host. So in fact the disks are still in use, bot got cleaned up by

Hello, I'm using libvirt and sanlock on qemu-kvm guests. Each guest has it's own Logical Volume for it's root filesystem. Sanlock is configured and working and prevents me from starting the same VM twice on multiple nodes and corrupting it's root filesystem. Each VM's domain XML resides on 2 servers that share the LVM volume group over fiber channel. In testing, I noticed

CentOS 6 Hi all, I am working on setting up sanlock + watchdog on a 2 node KVM pair. Sanlock is working beautifully and is preventing access to the VM disks by more than one process as it should across both boxes. I am attempting to test failure scenarios involving watchdog, but I am having a hard time getting it to actually reset the server. I am running wdmd with -D so I can see the
