ESXI 6.7 client creating Thick Eager zeroed vmdk files using ceph fsal
by Robert Toole
Hi,
I have a 3 node Ceph octopus 15.2.7 cluster running on fully up to date
Centos 7 with nfs-ganesha 3.5.
After following the Ceph install guide
https://docs.ceph.com/en/octopus/cephadm/install/#deploying-nfs-ganesha
I am able to create a NFS 4.1 Datastore in vmware using the ip address
of all three nodes. Everything appears to work OK..
The issue however is that for some reason esxi is creating thick
provisioned eager zeroed disks instead of thin provisioned disks on this
datastore, whether I am migrating, cloning, or creating new vms. Even
running vmkfstools -i disk.vmdk -d thin thin_disk.vmdk still results in
a thick eager zeroed vmdk file.
This should not be possible on an NFS datastore, because vmware requires
a VAAI NAS plugin to accomplish thick provisioning over NFS before it
can thick provision disks.
Linux clients to the same datastore can create thin qcow2 images, and
when looking at the images created by esxi from the linux hosts you can
see that the vmdks are indeed thick:
ls -lsh
total 81G
512 -rw-r--r--. 1 root root 230 Mar 25 15:17 test_vm-2221e939.hlog
40G -rw-------. 1 root root 40G Mar 25 15:17 test_vm-flat.vmdk
40G -rw-------. 1 root root 40G Mar 25 15:56 test_vm_thin-flat.vmdk
512 -rw-------. 1 root root 501 Mar 25 15:57 test_vm_thin.vmdk
512 -rw-------. 1 root root 473 Mar 25 15:17 test_vm.vmdk
0 -rw-r--r--. 1 root root 0 Jan 6 1970 test_vm.vmsd
2.0K -rwxr-xr-x. 1 root root 2.0K Mar 25 15:17 test_vm.vmx
but the qcow2 files from the linux hosts are thin as one would expect:
qemu-img create -f qcow2 big_disk_2.img 500G
ls -lsh
total 401K
200K -rw-r--r--. 1 root root 200K Mar 25 15:47 big_disk_2.img
200K -rw-r--r--. 1 root root 200K Mar 25 15:44 big_disk.img
512 drwxr-xr-x. 2 root root 81G Mar 25 15:57 test_vm
These ls -lsh results are the same from esx, linux nfs clients and from
cephfs kernel client.
What is happening here? Are there undocumented VAAI features in
nfs-ganesha with the cephfs fsal ? If so, how do I turn them off ? I
want thin provisioned disks.

lock issue for same clientid on the same node using NFS Ganesha 3.5
by pragash2here＠gmail.com
We are using NFS Ganesha 3.5 and occassionaly we see the following messages on the client host. The applications are no longer able to take locks.
They are all taking RDLCKs over the entire file range.
fcntl(19, F_SETLK, {l_type=F_RDLCK, l_whence=SEEK_SET, l_start=0, l_len=1800})
The host has multiple mounts of the SAME exported filesystem.
All the mounts are identical except for the mount path.
Each mount is sending the the SAME SETCLIENTID to the NFS Ganesha.
Any pointers much appreciated.

Enable POSIX ACL support in VFS FSAL?
by Sean Caron
Hello!
I noticed in the release notes that in V4.1 and onward, POSIX ACL
support is now available in the VFS FSAL but is disabled by default.
I looked through the documentation but I don't see any notes about the
parameter that might be used to enable said support.
Could someone please let me know how one might enable POSIX ACL
support in the VFS FSAL?
We're running the latest available stable build from PPA, 5.7GA.
Thanks!
Sean
