After 2 days of testing I wasn't able to reproduce my IO load issue on the test systems.
I'm running the same hardware as production: HP DL360 Gen10 w/ P408i-a, HP DL360 Gen9 w/ P440ar and HP DL360p Gen8 w/ P420i (4 x 2TB 870 EVO in RAID10, Smart Path enabled).
And the exact same versions of PVE: 8.3.0 (migrating from it) and 9.0.11
Until now I haven't seen the same "dd" process pop up at the end of the migration process and using 100% of IO and freezing the system and crashing some of the VMs, no matter what I did: cloning, live migration, migration of shutdown VMs
Also, my production PVE 9.0.11 HP DL360 Gen10 w/ P408i-a has no issues when running backup tasks and/or cloning, only when migrating VMs from PVE 8.3.0 and restoring them from the yet to be updated PBS v3.4.6
It's weird... I'll keep trying to replicate and diagnose the issue and update here if I make any progress.
Thanks!
