Re: [CentOS] Installing on USB Flash Drive
I'm doing exactly this on a trial basis with production servers. So far, it's working great. Some tips: 1) Flash drives are less reliable than HDDs. Software RAID1 is the way to go. A) Use two different makes of USB drives so that you have different failure characteristics. If either fails, replace it immediately. You can set it up so that if a thumb drive fails, you can yank it and set up its replacement without downtime. Practice this and document how you did it. B) When you replace the failed USB drive and set it up, you can manually remove it from the raid array and test it without causing downtime to verify that grub, etc. are set up properly on a different (offline) machine. Do this. C) Write speed is important! USB drives have an incredibly diverse range of performance. Don't cripple yourself trying to save $5. 2) Flash drives typically have weak write endurance. Think of write capacity like a disposable salt shaker. Once it's run out of salt, it's game over and you can't recharge it. A) Find and root out any remaining regular write activity on the thumb drives and move affected partitions to something else. B) Mount all partitions on the flash drive RAID with noatime C) Move your /tmp, /var partitions to spinning disks or proper SSDs. D) Never put swap space on the thumb drives. E) Verify the lack of write activity with iostat. Good luck. On 01/24/2014 03:06 PM, Matt wrote: Is it possible to install CentOS on a USB Flash Drive.

We know that it should update the boot config. And under most circumstances, it does. The problem is that under some conditions, while the boot config is updated with the new kernel information, the default= line is changed so that it points at the old kernel rather than the new one. So far, we don't fully understand why this happens. My theory is that it has something to do with manually creating the config file. I have not tested this yet, but I would guess that if you removed the comments at the top of the grub.conf file and then did a kernel update, you would see this behavior. -- Bowie ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Installing from USB flash drive
I successfully created an install media on a USB flash drive, but now I have a minor problem installing from it. Whenever I run the installer, it insists on installing grub on /dev/sdb (the flash drive) rather than /dev/sda (the hard drive where I'm installing everything). Is there a way to convince the installer to put grub in the right place? Should I just tell it not to install grub and then do a grub-install from a rescue prompt afterwards? -- Bowie ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Is there a way to convince the installer to put grub in the right place? If you are installing from a kickstart, or at least preparing the install using KS, yes. In my case it was easy, target of install was an IDE and source usb drive was detected as SCSI, in the kickstart file I was using I set: bootloader --driveorder=hda,sda granted I put that in a file that kickstart included, by building the file in the %pre section of the kickstart, i.e., I ran some detection routines to be sure of what I was putting in there. however for yours, because both show up as sd? you will need to be aware of BIOS/kernel detection order. The detection order may be different between booting the install media bootloader and booting the final system grub. Assuming you are using a kickstart file, you could probably program the %pre to figure out which is which by looking for a known UUID of the USB flash or its file system label and tell grub use anything else it finds first. I believe the final file you would need to look at is /boot/grub/device.map grub and grub-install take options for this file. Should I just tell it not to install grub and then do a grub-install from a rescue prompt afterwards? painful, but possible. Hopefully enough clues to be helpful. -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
