Back to replica 3 w/o arbiter. Two fio jobs running (direct=1 and direct=0), rebooting one node... and VM dmesg looks like: [ 483.862664] blk_update_request: I/O error, dev vda, sector 23125016 [ 483.898034] blk_update_request: I/O error, dev vda, sector 2161832 [ 483.901103] blk_update_request: I/O error, dev vda, sector 2161832 [ 483.904045] Aborting journal on device vda1-8.

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 ? On Fri, Sep 08, 2017 at 11:41:13AM +0200, Pavel Szalbot wrote: > Back to replica 3 w/o arbiter. Two fio jobs

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. Sanlock ======= At first I tried sanlock, but it seems if one node goes down unexpectedly,

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?

Could anybody explain this results? >sin(2*pi) -2.449213e-16 #should be zero >(10^16)*sin(log2(4)*pi) -2.449213 #should be zero too and explain what to do to correct this events? Thanks!!! Branimir K. Hackenberger

Hi all, When I attach a disk like this: <disk type='file' device='disk'> <driver name='qemu'

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… Van: 李笳平 [mailto:lijiaping@yovole.com] Verzonden: vrijdag 6 november 2015 10:14 Aan: Dominique Ramaekers; 'libvirt-users@redhat.com' Onderwerp: 答复: [libvirt-users] How could I do the guest

For usb I meant something like: <disk type='file' device='disk'> <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.

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: <filesystem type='mount' accessmode='passthrough'> <driver type='path' wrpolicy='immediate'/> <source dir='/export/to/guest'/> <target

Dear R-helpers! What it's means "Rank failure in Choleski decomposition" by using of function surf.gls {spatial}? Sincerely Yours Branimir K. Hackenberger

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

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 lito enble correct using of constrained ordination under BiodiversityRGUI environment?
