Hi.
Can someone please tell me how to make a performance test to a iscsi LUN?
I have a 4-node cluster running, connected to a ISCSI on a netapp. Above the ISCI there's a LVM.
All KVM machines reside on that Storage. But i only get a throughput of about 17MB/sec from within a virtual machine.
I now want to test the performance from a node directly.
i will make a testfile (1GB) and test the performance with
time cp testfile <netappmounted dir>
But where is that ISCSI LUN mounted??
with a simple fdisk -l i only get the virtual harddisks which are mounted as /dev/dm-xx
Is that the right way to test performance??
Please help
I just want to find out how long it takes to copy a testfile manually from the proxmox node to that iscsi lun
