12 physical drives are attached to one controller, 2 physical drives to another. I've never had any problems with it (once I installed the required cli tools for each hardware controller) - until today.ĭue to a very strange hardware setup, inherited from an ex-colleague, the server turns out to have two different RAID controllers active.

#Ubuntu raid monitor software

I've been using this plugin for years and it supports most software and hardware raid controllers. I wanted to monitor the current RAID status on an IBM x3650 M4 server, simply by using check_raid. Published on April 6th 2018 - Listed in Hardware Linux Monitoring To fix your broken Raid1’s on your Intel raid’s, use “dmraid -R ” and watch “dmsetup status” and wait for the ratio to be 1.Monitor dual storage (raid) controller on IBM x3650 M4 Consequently, i yanked the good 80gb drive from this set, and plugged in a 750gb Seagate, and was able to mirror back to that without a problem. It didn’t work with another Seagate drive, but it worked with a different drive. dev/sda: isw, 'isw_djhffiddde', GROUP, ok, 72303838 sectors, ~]# dmraid -s Isw_djhffiddde_Systemp2: 0 41720805 linear I also found a command to monitor this progress. On top of that, i could hear the grumblings of the WD, and i could see LED activity. Now, i added the new WDRaptor to this ~]# dmraid -R isw_djhffiddde_System /dev/sdb Booted up, and dmraid still showed the same stuff, inconsistent raid set. To figure out if its doing something, i turned the machine off and removed the new drive, and put in a Western Digital Raptor. I should look at the source code, but i cant be bothered.Īlright, so it appears that its not working.

Ok, so its not inconsistent now, but it is “nosync”, which i cannot figure out what it means. I cant really hear any grumblings from the drive, nor can i see the LED’s flash. dmraid thinks its working, but i cant see it. What’s happened? To be honest, I’ll never know – but it seems like it was not working. RAID set 'isw_djhffiddde_System' already activeĭevice 'isw_djhffiddde_System' is now registered with dmeventd for monitoring So, here ~]# dmraid -R isw_djhffiddde_System /dev/sdb

According to the man pages, and the Google, to repair it you use “dmraid -R /dev/” That’s what i want to see when a disk fails in my raid sets. So, dmraid tells me that the raid is broken and inconsistent. After fiddling with the bios for a few minutes (my machine wanted to boot form the newly installed drive, not the raid) i got back in, and this is what i ~]# dmraid -sĮRROR: isw: wrong number of devices in RAID set 'isw_djhffiddde_System' on /dev/sda I then, turned the machine off, and yanked a drive, inserted a different drive, and turned it back on. This tells me, my mirror set is running, and has two drives attached and all is happy. Then running “dmraid -r” gave ~]# dmraid -r The first thing i did, was find out what i’ve got. I then installed CentOS 5.5 32bit on this machine, and went to work. I booted up the machine, went into the Intel raid setup, and created a 20gb mirror partition called “System”. My test setup was a simple ICH6R machine with two 160gb Seagate hard drives. What *you* may find is that your implementation is different, but this posting should help you. Intel is the most common one, and that’s the one i generally have on all my Intel servers. Your raid can be from Intel, Nvidia, Promise and a few others who do implement it. Sort ofĭMRaid is the linux implementation of popular onboard RAID setups. So i spent a whole afternoon figuring this out. But that didn’t work in my test environments. But how do you do this on a Linux server which has no Storage Matrix software? After hours of Googling, i came across the command “dmraid -R”. On Windows, this is simple, you launch the Storage Matrix software and click rebuild (if it isn’t rebuilding automagically).

What do i do when (and they will) a drive fails? How does ISW handle it? But something has always really bugged me.

For many years this has worked absolutely perfectly with no issues on both Windows and Linux. For years, I’ve ran many small servers running the popular ICH/ISW Intel Storage Matrix RAID in Raid-1 configuration.
