Hi List, While doing offline migration, it was observed that the vm export and import are tedious tasks. Although storage has enough bandwidth, vm export and import happens at slow speed.
My primary guess is because it uses a 4k standard block size. A simple dd command can take bs as 1M and can complete the operation in faster speed & time. So my question, can I take a LVM vhd and write it as NFS VHD with dd ? e.g dd if=/dev/VG_XenStorage-b017a4de-8d8a-7320-8e0b-a19f33b1a014/VHD-d67407b9-514f-4a3c-bf7d-642c58931182 of=UUID.vhd bs=1M ? or can vhd-util coalesce -n /dev/VG_XenStorage-b017a4de-8d8a-7320-8e0b-a19f33b1a014/VHD-d67407b9-514f-4a3c-bf7d-642c58931182 -p -o UUID.vhd be used ? Thanks.
