Wozu ist die 192.168.1.100 gut? Mach eine Bridge auf eth0 und gib der die xx.yy.zz.2, das 2er Netz vergibst du in den VM's mit der Bridge als Netzwerkkarte, das Netz bleibt aber privat.? Ist das so gewollt?

Kannst du dem ODBC-Treiber Benutzernamen und Passwort aus der Datenbank direkt mitgeben? Das ganze sieht ja eher nach einem Netzwerktimeout von Windoof aus. Bei MS SQL kannst du einstellen ob Windoof Useraccount oder DB Account, mit DB Account gabs bisher nie Probleme.

HI there, one of my 5 Nodes reboots every 5 - 10 minutes, its a torture for my Ceph storage! the cluster runs 3 months whitout any problem but now it sucks. :-( Is there a timer (watchdog?) or something who can make this happen? i can't find anything in syslog or kern.log, its a reset and not...

Think about much more Ram (32+) and Softraid. I dont see it working with 2 x Windows AND MS SQL Server!

can you test with the unsecure migration flag ? Sorry for the late answer, was verry busy. I prefer not to touch! Its a production system and i dont want to crash the filesystems. Maybe im not lucky to repair it again and have to go offline for longer, dont want this nigthmare.

Alessandro i do the backup inside proxmox, from ceph to a nfs storage, u can select what vm-disc should be backed up und what vm (regardless where the vm is running). So if the VM switch from node1 to node2 the backup still works at the given time. The data backup is done inside the vm with...

Sorry for the late answer, was verry busy. I have used the free version but i changed it to the enterprise repro already. 5 Nodes and since i changed its never happen i guess.

U can speed up the latency with using 1 ssd for 4 or 5 spinners. But anyway the hardware will hit u with drbd also and gluster too. Ceph scales up, more discs - more speed, more nodes - more speed. (theoreticaly) :-) I think your limit is the gigabit network.

1 Disc for system all other for Ceph as JBOD. SSD for Journal if u want. But up2u! :) Good source is here: http://www.sebastien-han.fr/blog/

In the corner on the right top side u find something it called Search..... :-) https://forum.proxmox.com/threads/cluster-and-quorum.7786/

As i remeber i did this in proxmox 3.x with multible browser windows too and i think i was running in the same open knife. :-( My VM's had filesystem errors too when i restart them. :-( So i never ever moved more than 1 VM at the same time. :)

Maybe u forgot ? https://pve.proxmox.com/wiki/Ceph_Server You also need to copy the keyring to a predefined location. Note that the file name needs to be storage id + .keyring . storage id is the word after this in /etc/pve/storage.cfg : 'rbd:' # cd /etc/pve/priv/ # mkdir ceph # cp...

Better use Ceph! Thats realy cool stuff if u have a few disc per server! :-)

Yeah but if its not a dynamic disc u cant expand it lalter i remember, i think so? Most time i expand it the easy way via raid 0 in windows, so i dont risk the lose data i hope. :-)

i read this before and config like its writen. GRUB_CMDLINE_LINUX_DEFAULT="quiet nmi_watchdog=0" Can i test the softdog & proxmox combination is working?

What the hell is this? :-( All 6 OSD's still online....?

I use the stable version from here: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso Balloon drviver is 62.72.104.10200 dated 10.03.2015 Same version works for network Virtio adapter. Problem was the disc driver, he not let me convert the disc into...

One more questions :-) How can i find the source for /dev/watchdog0? (lsof doesnt help) :-( I dont find any Option in the Bios and with 2 watchdogs fencing will not work. :-( Or is it possible the config proxmox to use /dev/watchdog (softdog)?

My mounts after setup: /dev/pve/root / ext4 errors=remount-ro 0 1 /dev/pve/swap none swap sw 0 0 proc /proc proc defaults 0 0 I dont use any container so can i use the data partition and mount it at /var/lib/vz? My Storage is a Ceph storage only. I have some issues with virtio too, does...
