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

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

With V4-rc6 out and the year almost over we are almost there!
by Frank Filz 10 Dec '21

10 Dec '21

I just pushed V4-rc6. Next week is the last full week before the end of year holiday time and I expect to be the last merge before I tag 4.0 (which may happen separately on Monday the 20th). With the final push, I encourage anyone who has a github issue that has been marked "Needs Verification" to verify the issue with V4-rc6. Any additional testing folks are able to do would be much appreciated. Any patches that have been submitted to gerrithub but not yet merged will need to be wrapped up next week. Following the V4.0 tag, I will follow our standard practice where I do not fork off a v4-stable branch for a few weeks which gives the opportunity for a V4.1 update to include some bug fixes before I start merging new feature work for the V5 development stream. Thanks everyone. This has been a long release, but we have made some significant code improvements and fixed a lot of bugs and we do have some features of note: More information on the wiki: https://github.com/nfs-ganesha/nfs-ganesha/wiki/ReleaseNotes_4 POSIX ACL support for FSAL_CEPH Enhancements to Export Update (DBUS) and Reload (SIGHUP) protocol update (add/remove v3/v4 to export) Pseudo Path can be changed when reloading exports Refresh file system table (allows adding exports for new file systems) FSAL_PROXY_V3 FSAL_CEPH enhancement to release inodes quicker NFSACL POSIX ACL side-band protocol for NFSv3 Option to increase aggressiveness of MDCACHE releasing entries Can actually disable RQUOTA and NFSv3 when building Improvements to building on MacOS and other compilers FSAL_KVSFS Match xattr support up with RFC 8276 Add xattr to FSAL_CEPH Support BTRFS subvolumes as if they are separate file systems Said page still needs some updates so if anyone sees anything that needs updating, let us know. Thanks Frank Filz
