I simply did a pvecm add. I have no chance to recover any data from crashed machine.

Hi, Im trying a pve 2.1 cluster with ten servers. One of then crashed (mainboard ko), and I removed the node from the cluster, then i reinstaled pve in a new server with the old hostname, and then i joinned it again in cluster. Now I cant enter to the server thought web panel because it says...

Hi Dietmar, root@virtualnc03:~# fence_tool ls fence domain member count 3 victim count 0 victim now 0 master nodeid 1 wait state none members 1 2 4 Fence is working Ok, there is a dedicated ilo interface in isolated server, and I can see how it is rebooted. I can`t start the...

Im testing HA with this scenario: - 3 x PVE 2.1 fresh install, last full-upgrade - Fencing with ILO/IPMI working ok, with dedicated interface - 2 x KVM Ubuntu Server 12.04 VMs First I've configured HA in the ubuntu machines and HA puts both in same server. Second I isolated the server by...

Ok, it works but it needs a special configuration: Sunfire 2200 cant power up through ipmi, but 'fencing_ipmilan' exec a on-off command by default when it received a 'reboot' signal, so server goes down forever. You need to change the method to 'cycle': * cli: # fence_ipmilan -a 1.2.3.4 -l...

Hi, Im trying to configure fencing with ipmi in Sunfire x2200, but it has only the 'power off/cycle' avility, nor 'power up', it puts the mng interface off and its not possible to up de server. Is it enough for safe fencing/HA?

No problem, you can do a simple bash loop

Thank lastguru, Im going to try :) Regards.

Hi, Can we use vswap with this kernel in Proxmox 1.9?

Hi, I've migrate a lot of ESX machines to Proxmox, thats what i do: - First I create the KVM VM in proxmox with a 1GB vmdk disk (you cannot create a non-disk machine) - Second I detach the 1GB disk and copy the vmware disk to the vm path in proxmox - Third I attach the new disk and voila You...

Hi tom, I know i need to increase memory (failcounts are high), but... I dont understand this behavior, I mean, imagine an unexpected increase of memory in Apache, for example a DOS attack, or an adversisement response: Shouldnt openvz resource manager system anticipate the oom? Otherwise...

Hi, I have several vz containers and i've detected, from time to time, a oom-killer. For example: Nov 30 18:12:19 pm01 kernel: Fatal resource shortage: privvmpages, UB 133. Nov 30 18:58:51 pm01 kernel: apache2 invoked PF oom-killer: oomkilladj=0 Nov 30 18:58:51 pm01 kernel: Pid: 11130, comm...

Webbased client is more less the original TightVncViewer client. You can play and divide the problem, its simple to simulate the 'console' web click. Over the master node, create a vnc OTP session for a supossed VM 106 with vnc pass 'janzun' which is running in slave node '192.168.100.105'...

Yes, different protocol and port, of course. So what you want to do isn't so simple. I see two options: - Reverse proxy only for http[s], and map range port 5900-6000 to master cluster. Assuming you have a router, of course, otherwise we wouldnt taking about this. - Try to search some type of...

Mmm, I think there is no problem with iscsi because is a 'complete' disk in which you can do a snapshot clone, but export NFS is refered to a 'folder', and you should to do a whole clone. I dont have the servers to hand now, but dont know if could be possible to do some type of trick/hack for...

No. If im not wrong, its secured and warantied by random OTP passed to vnc applet through html code, and master node is the unique vnc 'broker'. Jesús Feliz.

Uou, you've a big and powerfull storage!!, and you need a ZFS Server acording to that (for dedup). More storage and less block size == more ram, of course ;) About zfs clone... Hum... I dont use it because i believe it only works for a filesystem (?), so it could be ok in a Proxmox disk (FC or...

Hi spirit, We have 1.8 ratio for now because i havent 50 VM cloned in this moment, ratio would be so better, of course. My stat with a mixed env: nmc@labnas:/$ zpool listNAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT ZFSLun 1.98T 684G 1.32T 33% 1.76x ONLINE - syspool...

I use ZFS Dedup (Nexenta) served to Proxmox by NFS since last year and its cool, but it depens on your scenario, of course. Dedup is a good choice when you need to clone a lot of similar machines, its incredible to copy a hundred of Windows XP 50 GB HD vms and to see that space in use its only...

Be carefull between AMD and Intel KVM live migration, i've experienced strange behaviours in some cases (maybe NX extension?) I dont remember the direction, but it works for me only in one way and, in the opposite, VM is frozen (Windows XP often), or lost network (Linux often)... so they need a...
