GlusterFS as virtual machine storage
Back to replica 3 w/o arbiter. Two fio jobs running (direct=1 and
direct=0), rebooting one node... and VM dmesg looks like:

GlusterFS as virtual machine storage
Oh, you really don't want to go below 30s, I was told.
I'm using 30 seconds for the timeout, and indeed when a node goes down
the VM freez for 30 seconds, but I've never seen them go read only for
that.
I _only_ use virtio though, maybe it's that. What are you using ?

sanlockd, virtlock and GFS2
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.

At first I tried sanlock, but it seems if one node goes down

答复: How could I do the guest mount operation from the host?
Hi,
Thanks for your response!
But when I use the ssh, I need to know the guest password, and actually it
belongs to network communication. I don’t know if the libvirt has some means just
like to control the domain to implement the operation?
Best Regards

Re: How could I do the guest mount operation from the host?
You can attach the disk on the usb bus (<target dev='sda' bus='sub'/> - Not 100% sure about this but probably in the right direction) and let the guest automount usb-storage…

Re: How could I do the guest mount operation from the host?
For usb I meant something like:

<driver name='qemu' type='qcow2' cache='none'/>
<source file='/kvmdata/disk/dk389_581.img'/>
<target dev='sda' bus='usb'/>
</disk>
If you want to use fiesystem passtrough, I think you have to look at p9 filesystem.

[ovirt-users] Re: Gluster problems, cluster performance issues
I would check disks status and accessibility of mount points where your
gluster volumes reside.

Hi,
I have tried usb and it doesn’t work. I don’t know if the filesystem tag could work…
I find in the formatdomain docs about the filesystem:

Yes, my modification is like you. I doubt that if the mount operation on the host is reasonable…
And what is p9?

GlusterFS as virtual machine storage
FYI I set up replica 3 (no arbiter this time), did the same thing -
rebooted one node during lots of file IO on VM and IO stopped.
As I mentioned either here or in another thread, this behavior is
caused by high default of network.ping-timeout. My main problem used
to be that setting it to low values like 3s or even 2s did not prevent
the FS to be mounted as read-only in the past (at least with

After some investigation I found out that constrained ordination is working
fine under R version 6.5.0 and 6.5.1 but not under any of newer versions. Is
it posible to repair/make something in for example newest version of R 7.0
