ESXI 6.7 client creating Thick Eager zeroed vmdk files using ceph fsal
by Robert Toole 07 Jan '25

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. ceph nfs export ls dev-nfs-cluster --detailed [ { "export_id": 1, "path": "/Development-Datastore", "cluster_id": "dev-nfs-cluster", "pseudo": "/Development-Datastore", "access_type": "RW", "squash": "no_root_squash", "security_label": true, "protocols": [ 4 ], "transports": [ "TCP" ], "fsal": { "name": "CEPH", "user_id": "dev-nfs-cluster1", "fs_name": "dev_cephfs_vol", "sec_label_xattr": "" }, "clients": [] } ] rpm -qa | grep ganesha nfs-ganesha-ceph-3.5-1.el7.x86_64 nfs-ganesha-rados-grace-3.5-1.el7.x86_64 nfs-ganesha-rados-urls-3.5-1.el7.x86_64 nfs-ganesha-3.5-1.el7.x86_64 centos-release-nfs-ganesha30-1.0-2.el7.centos.noarch rpm -qa | grep ceph python3-cephfs-15.2.7-0.el7.x86_64 nfs-ganesha-ceph-3.5-1.el7.x86_64 python3-ceph-argparse-15.2.7-0.el7.x86_64 python3-ceph-common-15.2.7-0.el7.x86_64 cephadm-15.2.7-0.el7.x86_64 libcephfs2-15.2.7-0.el7.x86_64 ceph-common-15.2.7-0.el7.x86_64 ceph -v ceph version 15.2.7 (<ceph_uuid>) octopus (stable) The ceph cluster is healthy using bluestore on raw 3.84TB sata 7200 rpm disks. -- Robert Toole rtoole(a)tooleweb.ca 403 368 5680
