Problem is that both the NFS server and iSCSI target are served by the same machine, so my best guess is that the I/O on the storage server is getting saturated. Have you tried creating a new VM on iSCSI instead ? Can you also try setting bandwidth limits at "Datacenter -> Options -> Bandwidth Limits" and then retry cloning operation ? >>kernel: blk_update_request: I/O error, dev sdb, sector 1762240503 op 0x9:(WRITE_ZEROES) flags 0x0 phys_seg 0 prio class 0 Is this on the storage server or the PVE host ? What does /dev/sdb represent in this case ? if it's a hard drive, it looks like it's having some hw issues ? Better to test with smartctl if that's the case. Y.
