Might also be the number of nfsd started on your Synology.

Thanks for the reply. Although it does happen during backups, causing
serious issues that require Proxmox server restart, it also happens
during the day. I don't see any saturation issues during the day, but
I'll start monitoring that.

So you're saying to set network bandwidth limits on the storage network
(I do keep a separate network for storage). I guess upgrading the
synology's with something that has 10GE would help as well.

Thanks,

Gerald

It appears that the NFS storage target was unreachable during that time...

I would guess that the network link used for accessing the NFS target is
getting saturated. This sometimes can be caused by running backup jobs,
and/or other tasks like VMs demanding high i/o to that destination.

There are no errors in the Synology logs, and the storage stays mounted and

accessible.


You mean that it stays accessible after the backups are finished (or
failed) and after the i/o operations return to the normal levels ?
Do you recall if there was any of the above happening during that time ?

I would set bandwidth limits either on the storage target or on the backup
jobs. See documentation for details on how to achieve this.
Even better, separate VMs from the backups if that's possible (i.e use
different storage/network links).

Sorry, that should be:


options vers=4,async,noatime,fsc,nodiratime


I'm using NFSv4

[PVE-User] NFS Storage issue

2019-04-24 Thread Gerald Brandt

Hi,

I have a Synology with High Availability serving NFS storage to Proxmox. 
A couple of months ago, this started happening:


Apr 24 12:32:51 proxmox-1 pvestatd[3298]: unable to activate storage 
'NAS' - directory '/mnt/pve/NAS' does not exist or is unreachable
Apr 24 13:08:00 proxmox-1 pvestatd[3298]: unable to activate storage 
'NAS' - directory '/mnt/pve/NAS' does not exist or is unreachable


It affecting backups and VM speeds. Any idea what is causing this? There 
are no errors in the Synology logs, and the storage stays mounted and 
accessible.


Any ideas what's going on?
