NethServer Version: 7.6
I try to update a Server but cannot get the latest Kernel, please have a look:
Server-1:
On another LAN, I have been able to update to the latest (I guess) ?
Server-2:
DNS-Servers are 8.8.8.8 and 8.8.4.4 on both Server…
I remember there was a problem with latest upstream kernel for 7.6 with current NethServer mail module.
see Problems with eMail / Dovecot
Could the kernel update be blocked from NethServer repo because of this?
I unlocked the config and locked it agn, after that I was able to update the server. I cannot say what the reason was for this… I tried it a few times (just with the GUI) also with reboots and so on…
Maybe it has something to do with the hardware, it is a HP microserver Gen 10. Nethserver is running as a vm with only 2GB of RAM. We are thinking abt to buy a more powerful Server…
@fausp, The HP Microserver used to be a great server for small companies. Especially the G8. It is upgradable with more RAM and a Xeon E3-1230 (v2), Then it makes a great low-cost server for virtualization.
However, I never used a G10 and I am not sure what options the G10 has with upgrading.
As alternative I can recommend a Supermicro miniITX based server with a Xeon D-xxxx processor. VERY energy friendly with quite some processing power. And It accepts ECC memory which is recommended if you use ProxMox with ZFS…
I currently use a supermicro miniITX with a Xeon D-1521 processor. With 16GB RAM and 6 disks (1 60GB SSD for cahce, 1 250GB HDD for Proxmox system, 2 2TB HDD for raid1 ZFS pool and 2 8TB HDD for raid1 ZFS pool) This system uses around 70W on average without spinning down any disks.
Yes, I use one as backup-server (proxmox 5.x installed on zfs…) mounted via NFS for my Proxmox Hypervisor running abt. 10 VMs and to backup all of my clients with Urbackup.
A friend use it with nethserver:
