Change NFS mount options

[carlosho17]

Hi

how can I change NFS mount options ?

I just have these lines in /etc/pve/storage.cfg

nfs: storagexxx
path /mnt/pve/storagexxx
server xxx.xxx.xxx.xxx
export /storage/nfs
content images



But I would like to have the equivalent to this in /etc/fstab:

storagexxx:/storage/nfs /nfs nfs rw,rsize=4096,wsize=4096,hard,intr,async,nodev,nosuid,noatime,relatime 0 0

Regards
Carlos

add the following line to the storage definition:

options rw,rsize=4096,wsize=4096,hard,intr,async,nodev,nos,uid,noatime,relatime

after adding this line, is there any way to remount it without restart my master node?

 

[dietmar]

Simply umount (mnake sure nobody uses the nfs share):

# umount /mnt/pve/storagexxx

I will get mounted again automatically.

Ok, thanks dietmar¡¡

another issues I have now after upgrading from 1.7 to 1.9 version, is that two machines, lenny with 2.6.26-2-amd64, freezes without any messages in syslog, simply the cpu goes to 80-90% activity. Those are using virtio. Since I remove it, and replace it with a e1000 it seems now its working for 30 min. Before those machines freezes in 10 min... . I got pve kernel version 2.6.32-6

I got pve kernel version 2.6.32-6

Please can you test with kernel from pvetest repository:

When I directly copy a file over SSH, I get 11Mb/s speed. But NFS backup is not that fast. Actually too slower.

I changed nfs mount in storage.cfg
options vers=3,rw,rsize=8096,wsize=8096

but does not seems to helped. Is there something I am missing? I am using nfs share to store vzdumps but it is slow.
