Missing LUN removal from kernel after removal of disk

Hi all, I'm not sure if this is more a Proxmox than a plugin problem, but when (for some reason, I'm still having trouble because qemu and vma as of Proxmox usage does not support CHAP auth), a disk is removed, the kernel is not notified. This yields lots(!) of error messages all 10 seconds when Proxmox does a rescan of the iscsi target. Example:

new volume ID is 'truenas-113:vm-100-disk-0'
new volume ID is 'truenas-113:vm-100-disk-1'
Rescanning session [sid: 3, target: iqn.xxx:storage01, portal: xxx,3260]
sh: 1: /usr/sbin/multipath: not found
map 'drive-scsi0' to 'iscsi://xxx/iqn.xxx:storage01/1' (write zeros = 1)
Rescanning session [sid: 3, target: iqn.xxx:storage01, portal: xxx,3260]

vma: can't open file iscsi://xxx/iqn.xxx:storage01/1 - iSCSI: Failed to connect to LUN : Failed to log in to target. Status: Authentication failure(513)

for each LUN and every 10 seconds.
