Hi I was thinking of building a small server for the office based on the new Ryzen processors (after they fixed the linux issue)
Something like this,
64GB ECC Ram
Asrock Rack X470D4U
Intel 905P drive as cache/slog
3x 10TB WD Red in RAID-Z2
I will be running a few VM's on them of...
Hmm I think I see what is happening.
Most if not all snapshots are very small, like 20MB.
But then once a day there is a snapshot that is very big +2GB.
It is syncing a range of snapshots so everything together is like 4GB.
For the VM's even more.
Now only to find out why some snapshots are...
yes I definitely understand what you are saying, although I don't think that is where this huge difference is coming from.
You are right though source record size was set to 8k and the destination to 128k, so changed that now.
Lets see if it helps ;)
I was hoping someone could help me clear something up.
When making a ZFS snapshot and sending it offsite the sizes don't really look to be what they should be.
What I mean is this, I made a snapshot and the size of the snapshot is 26.4M.
When transferring this same snapshot with zfs send /...
I have Proxmox working quite well with FreeNAS through this plugin.
But for some reason I get a terrible performance for a windows VM.
Netwerk speeds are ok at 1Gbit (tested both ways)
Netwerk speeds are also ok from inside a VM
Reading / Writing are also ok, local, from client and within a...
To answer my own question, add
command="zfs get -o value -Hp available,used",no-agent-forwarding,no-port-forwarding,no-pty,no-user-rc,no-X11-forwarding ssh-rsa AAAA
In the authorization_keys file before the key (until the ssh-rsa part offcourse)
with the ZFS over iSCSI you have to copy over the authorized keys file to your NAS.
But this would mean the nodes have root access to my NAS machine, which I do not want.
What is the command that they need to execute?
I would like to limit the access to only that command. (I would like my...
50% storage in use
6x disks HDD
1x SDD Samsung 860 Pro as ZIL
Processor: Intel(R) Xeon(R) CPU 5130 @ 2.00GHz (4 cores)
Memory: 32 GiB
CPU Utilization around 4% on average
Something very strange, I had a SMB service with a test share running.
I stopped the SMB service and suddenly the...
I'm trying this patch of GrandWazoo and it works as a charm, in that it can create VM's and migrate etc etc.
The performance crawls, Windows speed is unbearable and in Linux I get a write performence of about 15MB/s.
While on NFS I get about 80MB/s (1 Gbit line)
How did you set rr on BSD?
What performance are you getting, as the BSD / FreeNAS forums claim BSD won't work well in round robin mode.
I'm wondering is there a performance benefit to running iSCSI instead of NFS to FreeNAS?
Especially as the ZFS over iSCSI does not support MPIO yet according to the Wiki?
(I would bundle 2 x 1Gbit connections)
My containers get their IPv6 IP assigned through SLAAC, this works.
They can also ping and connect outside over ipv6.
But for some reason they won't accept any connection coming in.
Not from the internet, but also not locally on their public IP. (connections are open to the internet)
As far as...
One more thing I was wondering.
Would it make more sense to have one server with the storage and the VM's.
Or would it be more advisable to buy/build a NAS and run everything from there.
Don't think I will need to expand to more servers in the future.
Mm thinking a bit further, if you would have a Ryzen running.
It would have a max memory of 64GB.
If you then for example would have 48TB of zfs storage, would there be enough memory available to run VM's?
Maybe interesting here are two servers build with Ryzen,
and this one runs Proxmox
