Hi Proxmox Team,

We were in the testing and implemtation phase of the proxmox , we have tried to configure the IDRAC / ILO fencing , but unfortunaley we are ot able to achieve none of the fencing options , Please provide the proper steps are links to configure ILO / IDRAC fencing and testings steps.
With this testing only we will move forward with proxmox implementation and procuring a enterprie subscription .
Kindly help here.
 
Hello,

Might I ask why do you need to setup hardware fencing? In general the software-defined fencing is very reliable.
 
Hi Maximiliano,

Thanks for the replay!

Software-defined fencing means you mean to say watchdog fencing? We are not able to see any changes or logs wheather watchdog is fecning the server. Can you please explain how to can confirm that fencing is happened with watchdog?
 
Hi Maximiliano,

Please update the two things:
1. Fencing options.
2. FCP , NVME/FC protocols will be supported.
your kind help is required here.

It is a bit unfortunate that the fencing does not leave enough time for the journal to log the fencing to the disk, but you can see if a node was fenced by going to another (it could be the same too) host and check the logs for a 60s (or bigger) time window where the node was not part of the corosync quorum. Corosync will log every time a node has connected or disconnected from the cluster.

2. FCP , NVME/FC protocols will be supported.

Could you please elaborate what do you mean?
 
Hi Maximiliano,

Thanks for the replay,

we are planning mount the common storage in proxmox nodes using FCP protocol or NVME/FC protocol , But in proxmox UI i am only able to see scsi, NFS, SMB and ZFS , LVM etec.
 
If you have a setup where the disks can be accessed over multiple paths, you can check our multipath wiki article [1], there is some info therein which concerns FC.

The Linux kernel should recognize the disks as soon as you plug the cable, you can use the `lsblk` utility to check this. Once you setup multipath (if it is needed) you can then create a LVM (for example) storage on top of the disks provided by FC using the web UI.
