Re: Help: Install Centos 7 Raid 1 with UEFI boot

My preferred solution for boot when doing software RAID is to stick a small (that is physically small, Cruzier Fit are ideal) USB drive on the motherboard, and make that the boot device. When they are not being handled on a daily basis a decent make is incredibly reliable in my experience. In additi...

Re: NAT only partially working

I don't know what CentOS 5 and Shorewall did because they have gone now. In fact getting rid of a CentOS 5 server a couple of weeks ago, where sticking a crummy router from the ISP in the middle was not an option was the reason I had actually work out what the hell was going on and solve the problem...

Re: NAT only partially working

Though it is two years down the line I am going to post an update here because I now know what was going wrong back then, and the answer is very obscure and 99.99% of pages on how to do masquerading/NAT on CentOS7 using firewalld are missing a critical bit. Basically in the end it turn out that the ...

Re: Driver to utilize IBM DS3200

In the past the IBM DS3000, DS4000 and DS5000 storage arrays along with a range of other LSI nee NetApp rebadged Engenio storage used the RDAC driver from LSI/NetApp. However they ALL also work with the dm-multipath driver these days which is what you should be using, because the RDAC driver is depr...

NAT only partially working

This is probably the weirdest problem I have come across with CentOS7. Simple box has two NIC's one connects to the internal network, one is used to connect to a VDSL2 modem and a PPPoE link is brought up to get an internet connection. I have edited sysctl.conf to enable IP forwarding, and after som...

Re: /boot/efi partitions on software RAID1

I don't have an EFI system in which I am doing software RAID1. I was just making a general comment that if you are doing software RAID1 on a system with the suggestion that instead of messing about getting /boot onto the software RAID stick it on a USB drive plugged into the motherboard. Makes every...

Re: Install using LVM on Software RAID1

What I do is install a small (physical and size wise) USB flash drive on the motherboard and put /boot on that, makes everything much simpler when you are trying to do software RAID. Chances of a USB flash drive used just for boot failing are minimal and just in case it does I have a cron job that r...

Re: /boot/efi partitions on software RAID1

The other option is to have /boot on a USB drive plugged into your motherboard. I find this works really well

Re: grub install fails on Raid1 3TB

A work around, and in my opinion a better way of doing this is to put /boot on a USB thumb drive or USB drive module depending on what sort of headers are on your motherboard. Makes like a whole bunch easier and I just run an rsync script to copy /boot onto the RAID1 once a day in case the USB drive...

Re: Need Centos 5.5 x64 D9 DVD iso

The hack of two DVD's cannot be described in any way as elegant. It is just that a nasty and unnecessary hack. Every DVD drive is capable of reading dual layer media, the overwhelming majority of DVD burners can write dual layer DVD's of one format or the other, and the price of blanks is now well u...
