As you would probably expect from such a tiny operating system, the setup process went very quickly. I found this process to be especially amusing because the process not only looked like Windows NT Setup, even the filenames were immediately recognizable. The only supported file system is FAT.Īfter having me to set up my partition, ReactOS began copying operating system files. For example, setup explicitly told me that ReactOS does not support NTFS volumes. For those of you who have been in IT for long enough to remember Windows NT, the image below will probably feel really familiar.Īs I worked through the setup process, it quickly became apparent that ReactOS was not yet on par with Windows. The installation process reminded me a lot of installing Windows NT. Unfortunately, ReactOS did not seem to like the Generation 2 VM, so I resorted to Generation 1. #Reactos miditrail installSince ReactOS is designed to be Windows compatible, I was curious as to whether I could install it within a second generation Hyper-V VM. Generation 2 VMs perform better than first generation VMs but tend not to be compatible with as many operating systems. #Reactos miditrail isoThe Windows ISOs in the screenshot are over 3GB each, and even the Microsoft Office ISO is over 2 GB.įor the purposes of trying out ReactOS, I created a Generation 2 Hyper-V VM. If you look the figure below, you can see the ReactOS ISO alongside a few Microsoft ISOs. The ISO file that is used for installation is a mere 127MB in size. The first thing that caught my attention was the operating system’s tiny size. While there are lots of open source operating systems out there, the thing that makes this one different is that it is not a Linux build masquerading as Windows, but rather a Windows compatible operating system that has been built from the ground up.Įven though ReactOS has been around for a while, I had never bothered to take a serious look at it up until now. For a while now, I have been hearing about an open source operating system called ReactOS that is designed to be a Windows alternative.

All the files I'll have in the pool I have local or offsite backups of, I just don't want to serve out corrupt files, or miss the signs that I need to take action. The goal is to know when/if a drive or the pool is having any integrity errors since I have this odd fear that if a file is corrupted, it gets mirrored and that's it. So far I've been using zpool status and zdb and trying to grok their man pages but as I do that I'm wondering if there are other tools and commands I've missed in looking. I've been looking for how I can monitor the health of this pool, preferrably over SSH/CLI but I tend to keep finding web/GUI recommendations and systems like Proxmox, and I'm sure they're great, and something for my future, but right now I'm trying to understand some ZFS nuts and bolts on the command line. 2) allow the zabbix user to run 'zpool' and 'zfs' commands this is done by copying the 'zabbixsudo' file under /etc/sudoers.d directory 3) import the zbxexporttemplate. The smartmontools package comes with two utilities, smartctl which you can use to check your hard drives on the command line, and smartd, a daemon that checks. I'm new to ZFS, having previously used simple drive and LVM setups with rsynch for psudo-mirroring before on Linux. The -f is there are the disks are dissimilar sizes, so I get the smaller size, and that's fine right now. So how much RAM do you need, you can use the zdb command to check. Sudo zpool create -f zfs-alpha mirror /dev/sdb /dev/sdc raidz/raidz1 - minimum of 3 devices (one parity disk), you can suffer a one disk loss. On Ubuntu Server 20.04.3 I've created a 2 disk ZFS pool using the following from the Ubuntu page: Monit is particularly useful for monitoring daemon processes, such as those started at system boot.
