It worked but now I get the same problem with the device-mapper event daemon.

Nobody ?

I am getting a error all the time I want to restart my node. First I get the "A stop job is running for Monitoring of LVM2 mirrors..." and after a time it gets stuck at a watchdog error and I have to manually shutdown the node. It only happens when I have connected shared storage over iSCSI...

It occurs frequently. I will do a benchmark with the tool.

I only have it on the host. The host is giving this message.

So I set everything up with the vendor settings. I still have a message that is shown in the kvm of the node. device-mapper: multipath: blk_get_request() returned -12 - requeuing Where is this coming from and what can I do?

Regarding multipathing what are the recommended settings for Dell EQ storage? I only found a very old whitepaper from Dell. https://linux.dell.com/files/whitepapers/iSCSI_Multipathing_in_Ubuntu_Server.pdf

Hey, when I try to create a LVM on top of my iSCSI Target I get the following error. Can anybody help ? Thanks in advance.

Is it possible to use vlans in the iscsi network ? Not only attached to a vm ?

It is not possible to mount the storage on the two other nodes.

Perfect, thanks for your help!

It is working now. But for my understanding how is the best practice to handle this in a ha cluster with 3 nodes. Do I add this iscsi target now also to the two other nodes?

everything worked so far, but I can not add the lvm with help of the GUI. I have three nodes in the cluster do I need to add the iscsi target first to all nodes?

Okay I understand. But.. pgcreate: command not found

I understand that but how to do it with a multipath iscsi target ? I am not able to add it over the gui.

Hey, I connected my iSCSI target to the node with multipath. But I don't get it how can I give the storage now to proxmox to use it for virtual machines ?
