[pve-devel] high load on LV remove and iSCSI

[Dietmar Maurer]

Hi all,

one user reported very high load when he removes a disk which resides on LVM on top of iSCSI.
The storage backend is a netapp FAS2020.

Anyone seen that?

What can cause such high loads. Looking at the LVM source code reveals that LVM only wirtes
a few bytes of metadata, so this cannot cause the load. Any ideas?
