Full Discussion: Single LUN or multiple smaller LUNs for NFS sharing
Top Forums UNIX for Beginners Questions & Answers Single LUN or multiple smaller LUNs for NFS sharing Post 302994798 by hicksd8 on Tuesday 28th of March 2017 09:05:42 AM

Your question arises out of a fairly common scenario. Many sysadmins on this forum will have experienced such a thing and you may receive different answers. What I would say from my long experience is this.

If you are backing up over NFS (which is a very common thing to do and nothing wrong with that) then the bottleneck will be the network speed not the disk interface. Backup jobs have a habit of getting bigger over time and if you have to look at several volumes to find the necessary space, it makes things much more complicated to manage. Therefore, I would say that one big volume is much easier to manage because you can see what's on it all in one go, (and decide what old backups to delete to make room).

I would suggest that, if necessary, review your network interface speed and possibly upgrade and/or aggregate/team network interfaces to up the bandwidth.

Hope that helps. Let's see what others on here think.

systemd-networkd

SYSTEMD-NETWORKD.SERVICE(8)				     systemd-networkd.service				       SYSTEMD-NETWORKD.SERVICE(8)

NAME

       systemd-networkd.service, systemd-networkd - Network manager

SYNOPSIS

       systemd-networkd.service

       /lib/systemd/systemd-networkd

DESCRIPTION

       systemd-networkd is a system service that manages networks. It detects and configures network devices as they appear, as well as creating
       virtual network devices.

       To configure low-level link settings independently of networks, see systemd.link(5).

       systemd-networkd will create network devices based on the configuration in systemd.netdev(5) files, respecting the [Match] sections in
       those files.

       systemd-networkd will manage network addresses and routes for any link for which it finds a .network file with an appropriate [Match]
       section, see systemd.network(5). For those links, it will flush existing network addresses and routes when bringing up the device. Any
       links not matched by one of the .network files will be ignored. It is also possible to explicitly tell systemd-networkd to ignore a link by
       using Unmanaged=yes option, see systemd.network(5).

       When systemd-networkd exits, it generally leaves existing network devices and configuration intact. This makes it possible to transition
       from the initrams and to restart the service without breaking connectivity. This also means that when configuration is updated and
       systemd-networkd is restarted, netdev interfaces for which configuration was removed will not be dropped, and may need to be cleaned up
       manually.

CONFIGURATION FILES

       The configuration files are read from the files located in the system network directory /lib/systemd/network, the volatile runtime network
       directory /run/systemd/network and the local administration network directory /etc/systemd/network.

       Networks are configured in .network files, see systemd.network(5), and virtual network devices are configured in .netdev files, see
       systemd.netdev(5).
