Storage, gets cached in RAM instead of writing to disk

[monkieking]

Hello,

Let me start by saying that I'm pretty new to all of this

The problem:
I've added a disk to a VM running openmediavault and then shared a test folder using NFS.
When I'm adding something to the shared folder it gets cached to the RAM for the VM instead of actually writing it to the disk.

I can see the original contents on the disk in OMV but if I create a new file in proxmox on the disk, i.e. touch testfile, I cannot see it in OMV. The same goes if I create/add a file in OMV.

Am I missing some kind of setting to get this to work?

My configure for the disk below:

virtio0: /dev/disk/by-id/md-uuid-8dc1c44f:0ce6e1f3:f83efd32:7761571d,size=1953382464K

If you need any more information, please let me know. I'm sort of lost here

Hope anyone can help me.

Thanks,
Monkieking

does it flush to disk, if you launch "sync" command ?

maybe your storage have an agressive cache

I got it to write to the disk by adding this paramter to *.conf: cache=directsync.
The whole config for the disk is now:

virtio0: /dev/disk/by-id/md-uuid-8dc1c44f:0ce6e1f3:f83efd32:7761571d,cache=directsync,size=1953382464K

However, it still gets cached to the RAM and does not flush it by using the "sync" command. See attached.

What might be causing this or/and how can I troubleshoot it?

Thank you!
