Before add it to gui,
I think we need to add a deny with iothread and multiple disks, as it's buggy.
also need to verify how it's works with zfs...
can you try without "numa: 1" ?
does it work for you ? (I don't have tested it)
can you give me result of "cat /proc/cpuinfo" of a working node, and node2 ?
Ok, I have tested with iothread, and I have problem , migration crashing or qemu process crashing.
Also with only 1disk.
So it seem that qemu is...
yes, it should work.
maybe a little bit overkill.
you can give a try at
or wait for next ceph release (mimic), which...
you don't need to define vlan interfaces in /etc/network/interfaces
if you define vlan tag in vm configuration, proxmox will create the...
they are running fine (around same perf than 3610 or 3710), but take care of dwpd 1.
Hi, I'm currently working on implementation on vxlan + bgp evpn. This should give us something like vmware nsx. (with anycast gateway on proxmox...
it's only supported since win8/2012. (maybe 8.1,2012r2)
(you also have a gui, "optimize disk")
note that since luminous + bluestore, jemalloc don't work well. (because of rocksdb)
Ceph devs said that tcmalloc if fine now, since they have...
if you are concerned about dataloss, cache=none.
rbd_cache is 32mb (can be tuned), so even with fsync you can loose 32mb. (but you'll don't have...
@David : do you have tried with a bigger file size ? (as it's random write, with a small file, you have more chance to have 2 block near each...
if you enable cache=writeback on vm, it'll enable rbd_cache=true.
ceph have a feature by default
rbd cache writethrough until flush = true.
The problem is coming from network latency + ceph latency. If you copy 1 file, sequentially and with small blocks, it's iodepth=1. (same with dd...
how do you bench it ? rados bench use multiple thread.
try to test with fio, with iodepth=32 for example.
if you still have access through ssh:
#apt-get install proxmox-ve
should fix it
yes, it still missing support in librbd
you can also use this external script, to backup with rbd snapshot, rbd-diff export feature.
I'm using chrony too now, no more clock screw and it's also able to manage leap second.
