move disk/restore backup high load on other vm's

[sander93]

Hello,

i am buzzy with moving my vm's to a ISCSI storage (so i can use proxmox HA with shared storage) but when i choose for moving a disk from GUI he try's to move the vm-disk fast as possible, on that moment other vm's already on the ISCSI cannot reach the storage on time and get very high load (from 20 to 40 to 80 to 100 in Linux).

The same problem i also have when i choose to make a backup and restore them on the ISCSI storage, creating them work great (with bwlimit) but restore the backup also make other vm slow and get high load.

who can help me?

Gr,

Sander

Ps. Sorry for my bad English.

i test something a few minutes ago, when i do a live move of a disk (of a running vm) the speed is lower, but it is not affecting other VM's.

so only backup restore and offline vm disk moving is creating high io load
