CEPH RGW and VMWare vSphere 6.7 mdcache_find_keyed_reason
by Martin G
Dear all,
I ran into trouble connecting VMWare 6.7 to CEPH cluster exported via RGW and Ganesha. Once the datastore is created, the ganesha thread is stuck at 100% CPU in mdcache_find_keyed_reason, preceeded by pthread mutex lock and unlock.
I am at Nautilus, deployed by Ansible, running on latest CentOS 7. The issue appeared in Ganesha 2.7.3 and also in 2.8.
Stacktrace from perf top here: https://imgur.com/a/rQ3AKfy
I would greatly appreciate any clues or hints on what causes this.
Thanks,
Martin

nfs-ganesha freeze after a few hours
by andre.roberge＠maskicom.net
Hi,
I’m running a nfs-ganesha on a virtual server with SR-IOV(Intel XP520) which job is basically recording 167 channels of TV feed for a time shift function. The set-up would run for hours without any issues than the VM would just freeze with no apparent reason.
My Ceph cluster is running fine and are barely using the available storage the load on the server is minimal.
There is no error on the Ceph side the nfs-ganesha virtual machine just freeze.
The nfs-ganesha server is set-up with BGP to the host using frrouting 7 into leaf/spine typologies which is working fine.
Here is my mount for the NFS
10.70.0.67:/cephfs/timeshift1 /mnt/cephfs nfs4 noatime,soft,nfsvers=4.1,async,proto=tcp 0 0
Here is my config for Ganesha

related?

Re: NFS export of ZFS filesystems
by Kaleb Keithley
Sending it only to me makes it hard for other people to see your response.
;-) cc: support(a)lists.nfs-ganesha.org
There's no FSAL_ZFS in the ganesha sources. There was a FSAL_ZFS in
ganesha-2.5, but it was removed in 2.6; the FSAL API had diverged and
nobody was maintaining it. (And Ubuntu 10.04? That's seriously old. The
oldest Ubuntu that we package for in the gluster or ganesha PPAs is 16.04.)
Off hand I'd say try FSAL_VFS and set the Path to your zfs fs that's backed
by the zpool.

NFS export of ZFS filesystems
by john＠kheironmed.com
OS - Ubuntu 10.04.3 LTS
ZFS 0.7.5-1ubuntu16.6
Ganesha version 2.6.0.2
I am not using Gluster. Teh documentation says that if I set sharenfs=on for a given zfs filesystem it should be exported by NFS
However I do nto see this happening - can someone help me to set up /etc/ganesha/ganesha.conf in this mix of OS and ZFS?
Also I note ubuntu16.6 in the ZFS version ....

Re: [ceph-users] [Nfs-ganesha-devel] 2.7.3 with CEPH_FSAL Crashing
by Daniel Gryniewicz
Client::fill_statx() is a fairly large function, so it's hard to know
what's causing the crash. Can you get line numbers from your backtrace?
