Can't import disks into proxmox - dreaded "volume deactivation failed"

[Matt998]

Hello,
"new" proxmox user here trying to migrate some VMs from hyper-v to proxmox. I did extensive searches for a possible solution but I just got more confused.

THE PROBLEM:

When I try to import .img images using the command qm importdisk <ID> <image> <storage> <lvm> sometimes, fails with the following error:

importing disk 'wsus1.img' to VM 113 ...
Logical volume "vm-113-disk-0" created.
transferred 0.0 B of 700.0 GiB (0.00%)

can't deactivate LV '/dev/fast/vm-113-disk-0': Logical volume fast/vm-113-disk-0 in use.
Logical volume "vm-113-disk-0" successfully removed.
volume deactivation failed: fast:vm-113-disk-0 at /usr/share/perl5/PVE/Storage.pm line 1246.

It happens with other VMs to... but other (smaller) migrate just fine. Nobody is altering the configuration of the cluster during the import.

MY SETUP

I have a three node setup with HA, storage is a SAN Dell M5024 which is accessed via iSCSI (multipath). I use two volumes, "fast" and "slow". Some more config info:

File /etc/multipath.conf

blacklist {
wwid .*
}

blacklist_exceptions {
wwid "3600c0ff000f9459476406f6501000000"
wwid "3600c0ff000f94837b83c6f6501000000"
}

multipaths {
multipath {
wwid "3600c0ff000f94837b83c6f6501000000"
alias mpath-fast
}
multipath {
wwid "3600c0ff000f9459476406f6501000000"
alias mpath-slow
}
}

defaults {
polling_interval 2
path_selector "round-robin 0"
path_grouping_policy multibus
uid_attribute ID_SERIAL
rr_min_io 100
failback immediate
no_path_retry queue
user_friendly_names yes
}

output of multipath -ll
