Dear Gilles,
Many thanks ! It seems more simple as I already read before on Internet !
So I did a lsscsi and the output is :
[0:2:0:0] disk DELL PERC H710 3.13 /dev/sda
[0:2:1:0] disk DELL PERC H710 3.13 /dev/sdb
[5:0:0:0] cd/dvd TSSTcorp DVD+-RW SN-208BB D150 /dev/sr0
[8:0:0:0] disk DELL MD32xxi 0780 /dev/sdd
[8:0:0:31] disk DELL Universal Xport 0780 -
[9:0:0:0] disk DELL MD32xxi 0780 /dev/sdf
[9:0:0:31] disk DELL Universal Xport 0780 -
[10:0:0:0] disk DELL MD32xxi 0780 /dev/sde
[10:0:0:31] disk DELL Universal Xport 0780 -
[11:0:0:0] disk DELL MD32xxi 0780 /dev/sdg
[11:0:0:31] disk DELL Universal Xport 0780 -
Of course sda and sdb are HD on the server. Now fdisk -l give me :
NO output on /dev/sdd and /dev/sdg
And a strange and same output for sde and sdf : 2096.2GB !
And pvs show me :
/dev/sdd: read failed after 0 of 4096 at 0: Input/output error
/dev/sdd: read failed after 0 of 4096 at 2096239214592: Input/output

So as you wrote, I think that stop VMs and restart open-iscsi will be a
good starting point !
Many thanks for your advises. I will post further results soon.

Dear all,
For the moment I have two proxmox nodes (2 Dell R720), not running
in cluster, and both are connected to a Dell MD3220i SAN. At the
beginning the SAN has only 500Gb of HD, then now I added in the SAN
several discs and add them in the SAN interface. I have now 3Tb in
the SAN. But proxmox nodes are still using and viewing 500Gb.
Can someone help me in procedure to extending the size in Proxmox ?
I found several web pages on this, but not all pages are saying
exactly the same.... and I don't want to crash all nodes and VMs....
Many thanks and have a nice day.

Hello,
I suppose your LUN is presented to your nodes via iSCSI.
This bring a SCSI device to your nodes. Find wihch, with lsscsi for
example (install it via "apt-get install lsscsi").
Suppose that it is /dev/sdb.
Look at its size with fdisk -l /dev/sdb.
If it's 500GB, you will have to reconnect the iSCSI Target, and
probably have to stop your VMs...
"/etc/init.d/open-iscsi restart"
If the size is good (3TB), then let's go one level up.
Here I also suppose you have LVM on top of iSCSI.
running "pvs" as root will list your PVs with their size and free space.
Here, you'll see that /dev/sdb is 500GB and has free space.
You can resize it with "pvresize /dev/sdb".
After that, your VG will be bigger, because it contains the resized PV.
And you can add more VMs and disks inside that storage.
