/etc/multipath.conf is overwritten without backup. This results in ugly volume names, if allready configured
e.g.
multipaths {
multipath {
wwid "360030d908bc58402f10091cb44f54d46"
alias "DS_pve-r320-01_zfs_01"
}
/etc/iscsi/iscsi.conf is changed with backup, that's fine. But there are settings changed, which are not documented in the Proxmox DataCore Rollout documentation!
pve-r320-01:/etc/iscsi # diff iscsid.conf /tmp/iscsid.conf
