[SOLVED] Change NFSv3 to NFSv4 without reboot

[gbr]

Hi,

I've created an NFS store for Images and Backups. Proxmox, of course, mounted the new storage as NFSv3. I went into /etc/pve/storage.cfg to change it to NFSv4 (vers=4). After some searching here, I couldn't find the answer to my question.

How do I get Proxmox to re-mount the storage, without rebooting the server?

Gerald

ps: any idea when we'll get NFSv4 implemented?

Re: Change NFSv3 to NFSv4 without reboot

I answered my own question. Sometime I forget it's all Linux underneath.

I umounted the NFSv3 partition on each server in the cluster, and then mounted them again with vers=4


# umount /mnt/pve/NFS_FAILOVER_RAID1
# mount -o 'rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys' 192.168.20.100:/proxmox /mnt/pve/NFS_FAILOVER_RAID1


fsyncs/second dropped a tad, but write throughput increased.

NFSv3:
fsyncs/second: 1366.35
# dd of=/dev/zero of=/tmp/dd.out bs=8k count=1000k
838860800 bytes (8.4 GB) copied 200.1 s, 42.1 MB/s

NFSv4
fsyncs/second: 1184.91
# dd of=/dev/zero of=/tmp/dd.out bs=8k count=1000k
838860800 bytes (8.4 GB) copied 88.17 s, 95,1 MB/s
