Is the ceph cluster on dedicated nodes ? or vms are running on same nodes than osd daemons ? >>And I precise that not all VMs on that pool crashed, only some of them >>(a large majority), and on a same host, some crashed and others not. Is the vm crashed, like no more qemu process ? or is it the guest os which is crashed ?

Some VMs that stopped were running for a long time, but some other had only 4 days uptime. And I precise that not all VMs on that pool crashed, only some of them (a large majority), and on a same host, some crashed and others not. We use Proxmox, so I think it uses librbd ? _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
