These are a family of controllers called PERC by -Dell, and is present in several old PowerEdge servers, and I recently -got my hands on one of these. I had forgotten how to handle this RAID -controller in Debian, so I had to take a peek in the -<a href="https://wiki.debian.org/LinuxRaidForAdmins">Debian wiki page -"Linux and Hardware RAID: an administrator's summary"</a> to remember -what kind of software is available to configure and monitor the disks -and controller. I prefer Free Software alternatives to proprietary -tools, as the later tend to fall into disarray once the manufacturer -loose interest, and often do not work with newer Linux Distributions. -Sadly there is no free software tool to configure the RAID setup, only -to monitor it. RAID can provide improved reliability and resilience in -a storage solution, but only if it is being regularly checked and any -broken disks are being replaced in time. I thus want to ensure some -automatic monitoring is available.</p> - -<p>In the discovery process, I came across a old free software tool to -monitor PERC2, PERC3, PERC4 and PERC5 controllers, which to my -surprise is not present in debian. To help change that I created a -<a href="https://bugs.debian.org/1065322">request for packaging of the -megactl package</a>, and tried to track down a usable version. -<a href="https://sourceforge.net/p/megactl/">The original project -site</a> is on Sourceforge, but as far as I can tell that project has -been dead for more than 15 years. I managed to find a -<a href="https://github.com/hmage/megactl">more recent fork on -github</a> from user hmage, but it is unclear to me if this is still -being maintained. It has not seen much improvements since 2016. A -<a href="https://github.com/namiltd/megactl">more up to date -edition</a> is a git fork from the original github fork by user -namiltd, and this newer fork seem a lot more promising. The owner of -this github repository has replied to change proposals within hours, -and had already added some improvements and support for more hardware. -Sadly he is reluctant to commit to maintaining the tool and stated in -<a href="https://github.com/namiltd/megactl/pull/1">my first pull -request</A> that he think a new release should be made based on the -git repository owned by hmage. I perfectly understand this -reluctance, as I feel the same about maintaining yet another package -in Debian when I barely have time to take care of the ones I already -maintain, but do not really have high hopes that hmage will have time -to spend on it and hope namiltd will change his mind.</p> - -<p>In any case, I created -<a href="https://salsa.debian.org/debian/megactl">a draft package</a> -based on the namiltd edition and put it under the debian group on -salsa.debian.org. If you own a Dell PowerEdge server with one of the -PERC controllers, or any other RAID controller using the megaraid or -megaraid_sas Linux kernel modules, you might want to check it out. If -enough people are interested, perhaps the package will make it into -the Debian archive.</p> - -<p>There are two tools provided, megactl for the megaraid Linux kernel -module, and megasasctl for the megaraid_sas Linux kernel module.
