NFSv3 active-passive cluster with FSAL CephFS and keepalived - Stale file handle after restart and also failover

by rainer.stumbaum＠gmail.com

Hi, I configured five unrestriced LXC containers on Proxmox and also set lxc.seccomp.profile to empty. This is my configuration: root@nfsshares-a:~# egrep -v '^[[:blank:]]*#|^[[:blank:]]*$' /etc/ganesha/ganesha.conf NFS_CORE_PARAM { Enable_NLM = false; Enable_RQUOTA = false; Protocols = 3,4; mount_path_pseudo = true; } NFS_KRB5 { Active_krb5 = false; } NFSv4 { RecoveryBackend = rados_ng; Minor_Versions = 1,2; } MDCACHE { Dir_Chunk = 0; } EXPORT_DEFAULTS { SecType = "sys"; Squash = No_Root_Squash; Attr_Expiration_Time = 0; } CEPH { } RADOS_KV { UserId = "ganesharecov"; } RADOS_URLS { UserId = "ganeshaurls"; watch_url = "rados://nfs-ganesha/ganesha-namespace/conf-nfsshares"; } %url rados://nfs-ganesha/ganesha-namespace/conf-nfsshares root@nfsshares-a:~# And this is an example export. The other exports just have different clients for the other paths. root@proxmox07:~# cat /tmp/export-1 EXPORT { FSAL { secret_access_key = "AQDm7eFfJWvhIBAAuI++d0SNkdylNkMx5t/N8w=="; user_id = "ganesha"; name = "CEPH"; filesystem = "cephfs"; } CLIENT { clients = 10.20.56.254; squash = "no_root_squash"; access_type = "RW"; } pseudo = "/"; squash = "no_root_squash"; access_type = "NONE"; path = "/"; export_id = 1; transports = "TCP"; protocols = 3, 4; } Mounting filesystems works fine, but as soon as I restart the nfs-ganesha daemon I get a stale file handle on the client. Looking at root@nfsshares-a:~# ganesha-rados-grace --userid ganesharecov --pool nfs-ganesha --ns namespace-ganesha dump cur=1 rec=0 ====================================================== nfsshares-a E nfsshares-b E nfsshares-c E nfsshares-d E nfsshares-e E root@nfsshares-a:~# The nodes never loose the E state. These are the permissions on ceph: root@proxmox07:~# cat /etc/pve/priv/ceph.client.ganesha*.keyring [client.ganesha] key = <removed> caps mds = "allow r path=/, allow rw path=/vol" caps mon = "allow r" caps osd = "allow class-read object_prefix rbd_children, allow rw pool=cephfs_data, allow rw pool=nfs-ganesha" [client.ganesharecov] key = <removed> caps mon = "allow r" caps osd = "allow class-read object_prefix rbd_children, allow rw pool=nfs-ganesha" [client.ganeshaurls] key = <removed> caps mon = "allow r" caps osd = "allow class-read object_prefix rbd_children, allow rw pool=nfs-ganesha" root@proxmox07:~# Which service account is used to remove the E state on ceph? Do I have a permission problem?

Ganesha 3.5

by Daniel Gryniewicz

Since Ceph Pacific has come out, with the changes that break building Ganesha 3.4 and earlier against it, I've released a 3.5 with just the fix to build against Ceph Pacific. There's no associated ntirpc release. Daniel

Bind_address ignored in NFS Ganesha 2.7 to NFS Ganesha 3.4?

by TomK

Hello All, Bind_address appears to be ignored in NFS Ganesha 2.7 to NFS Ganesha 3.4? This used to work in Ganesha 2.6. Do I need to add a parameter to my config to make this work again? [root@nfs03 ~]# vi /etc/ganesha/ganesha.conf [root@nfs03 ~]# [root@nfs03 ~]# [root@nfs03 ~]# grep -Ei Bind_addr /etc/ganesha/ganesha.conf Bind_addr = 192.168.0.125; [root@nfs03 ~]# [root@nfs03 ~]# grep -EiB5 Bind_addr /etc/ganesha/ganesha.conf KeytabPath = /etc/krb5.keytab ; Active_krb5 = YES ; } NFS_Core_Param { Bind_addr = 192.168.0.125; [root@nfs03 ~]# [root@nfs03 ~]# [root@nfs03 ~]# netstat -pnltu|grep -Ei 2049 tcp 0 0 0.0.0.0:2049 0.0.0.0:* LISTEN 5412/ganesha.nfsd udp 0 0 192.168.0.125:2049 0.0.0.0:* 5412/ganesha.nfsd [root@nfs03 ~]# rpm -aq|grep -Ei ganesha nfs-ganesha-mount-9P-2.7.6-2.el7.x86_64 nfs-ganesha-utils-3.4-1.el7.x86_64 centos-release-nfs-ganesha28-1.0-3.el7.centos.noarch nfs-ganesha-3.4-1.el7.x86_64 nfs-ganesha-proxy-3.4-1.el7.x86_64 nfs-ganesha-vfs-3.4-1.el7.x86_64 centos-release-nfs-ganesha30-1.0-2.el7.centos.noarch nfs-ganesha-gluster-3.4-1.el7.x86_64 [root@nfs03 ~]# -- Thx, TK.

Ganesha network switch ACLs

by Becker, Jeffrey C. (ARC-TN)[InuTeq, LLC]

Hi. I’d like to clamp down the network between my Ganesha server (using Proxy FSAL) and the server that Ganesha is acting as a Proxy for (the one serving directories over NFSv4). Can I limit the network to only allow NFSv4 traffic? Thanks. -Jeff

Initial testing with ESXi 6.7

by swarnock＠warnocksolutions.com

Hello All, I am attempting to get nfs-ganesha 3.0.3 under Ubuntu 20.04 working with ESXi. While I can successfully mount the NFS export I receive regular errors while performing any kind of file work through ESXi. The volume /vdb is just raw formatted with XFS and the environment is completely virtual. Any suggestions for debugging this farther as this is my first time trying out this configuration.
