can't mount an export domain with 4K block size (VDO) as PosixFS (xfs)
After this (https://devconfcz2020a.sched.com/event/YOtG/ovirt-4k-teaching-an-old-dog-new...) I sure do not expect this (log below): Actually I am trying to evaluate just how portable oVirt storage is and this case I had prepared a USB3 HDD with VDO, which I could literally move between farms to transport VMs. Logical disks are typically large for simplicity within the VMs, QCOW2 and VDO assumed to compensate for this 'lack of planning' while the allocated storage easily fits the HDD. Once I got beyond the initial issues, I came across this somewhat unexpected issue: VDO storage uses 4k blocks all around, but evidently when you mount an export domain (or I guess any domain) as POSIX, 512byte blocks are assumed somewhere and 4k blocks rejected.

Vdsm learned a few tricks but is still old :-)
I sure do not expect this (log below):
Actually I am trying to evaluate just how portable oVirt storage is and this case I had prepared a USB3 HDD with VDO, which I could literally move between farms to transport VMs. Logical disks are typically large for simplicity within the VMs, QCOW2 and VDO assumed to compensate for this 'lack of planning' while the allocated storage easily fits the HDD.
Once I got beyond the initial issues, I came across this somewhat unexpected issue: VDO storage uses 4k blocks all around,
VDO has 512 bytes emulation mode. This is how gluster used VDO before 4.3.8.
but evidently when you mount an export domain (or I guess any domain) as POSIX, 512byte blocks are assumed somewhere and 4k blocks rejected.
Yes, NFS and POSIX (internally NFS) storage domains do not support 4k. With NFS we cannot detect storage domain block size, since NFS does not use direct I/O on the server side, so we kept the old configuration, 512. Theoretically we can change the code to default to 4k in this case, but it was never tested. POSIX was never tested wth 4k and since internally it is NFS, it has the same limits. It it likely to support 4k if we create a specific storage class for it, like local storage. Why do you need VDO for export domain? qcow2 keeps only the used data. You don't have enough space on the disk for keep all VMs in qcow2 format?
I'd say that is a bug in VDSM, right?
No, this is unsupported configuration. export domain is using safelease, which does not support 4k storage, and since export domain it is deprecated and safelease is unmaintained, it will never support 4k. If you need 4k support for POSIX or NFS storage *data* domain, this is something that can be considered for a future version, please file RFE for this. Nir

I like playing with shiny new toys and VDO is one :-) Actually with that it shouldn't matter if whatever is put on top actually has spare allocation in the file format or just blocks with zeros, which makes for a reusable HDD in case I am working with imageio images that are raw. Good to know that using NFS directly won't cost extra performance, because that's how I got around the 4K issue. Alas, plenty of qemu-img imports still fail with the ENOENT error on the 3nHCI gluster. From what I am reading between the lines, oVirt would be rock solid, if somebody didn't want to compete with Nutanix and had put Gluster underneath... With a 25% success rate at trying to transfer VMs from 4.3 to 4.4 I am... in no position to migrate, really. Trying the backup domains next, but their documentation is pretty awful if non-existent.
