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
NFS_Core_Param

}

}
}
Here is my Ceph status at the freeze time.

Any guidance on how to resolve this issue would be appreciated
