I don't _think_ anything special will happen - md RAID doesn't go actively looking for drives like that AFAIK. And RAID 1 means you should be able to ignore RAID and just access the contents directly.

There are some errors on my root filesystem, so I need to fsck it. In order to do this while the filesystem is unmounted, I'm booting from the install disk. However, since the filesystem is on an mdraid device, I'm not sure of the right way to get it assembled so I can check it. If I do, mdadm --examine --scan, then I get this: ARRAY /dev/md/2 metadata=... (and others, but I'm

I have a CentOS 7 server that is running out of memory and I can't figure out why. Running "free -h" gives me this: ????????????? total??????? used??????? free????? shared? buff/cache?? available Mem:?????????? 3.4G??????? 2.4G??????? 123M??????? 5.9M??????? 928M??????? 626M Swap:????????? 1.9G??????? 294M??????? 1.6G The problem is that I can't find 2.4G of usage.? If I look

Does anyone know of a cheap temperature sensor that will work with Linux? I don't need a fancy monitoring appliance, I just want a simple sensor that I can connect to one of my monitoring servers to let me know if the server room is getting hot. -- Bowie

I am trying to upgrade my system from 500GB drives to 1TB. I was able to partition and sync the raid devices, but I cannot get the new drive to boot. This is an old system with only IDE ports. There is an added Highpoint raid card which is used only for the two extra IDE ports. I have upgraded it with a 1TB SATA drive and an IDE-SATA adapter. I did not have any problems with the system

Give a specific symptom. This was brought to my attention because one program was killed by the kernel to free memory and another program failed because it was unable to allocate

My apologies if this is a bit off topic... I am going to start doing backups to removable hard drives and I will need to send these hard drives to an off-site storage facility. I am looking for some way to protect the drives after I pull them out of the system. I was hoping to find some kind of clamshell enclosure similar to what is used with external hard drives, but so far I haven't found

I have used the package-cleanup utility to remove old kernel packages, but I noticed that it only removes the 'kernel' and 'kernel-devel' packages. It does not touch 'kernel-smp', 'kernel-hugemem', etc. What is the recommended method of cleaning up these other kernel packages? Should I just 'yum remove' the ones I don't need? Some of my servers have a

What's the deal with all of the new dependencies for xulrunner-devel in the last update? I'm updating my servers and the update for xulrunner-devel is forcing me to install 43 new packages! Is this a packaging problem, or are all of those packages really needed? For the moment, I've been removing xulrunner-devel from my machines to avoid the problem. I figure since it is a

I updated my i386 systems without any problems, but when I tried to update one of my x86_64 systems, I got an error from yum.
