I am considering buying a small, and therefore easily portable, computer as an alternative to the laptop I already have. Obviously it would not have battery, a screen, nor a keyboard etc. but more or less be an easily portable computing unit to move between offices where a keyboard and monitor(s) could then be connected. I want to run CentOS 7, later CentOS 8. The smaller, the better, however,

I plan to upgrade an existing C7 computer which currently has one 256 GB SSD to use mdadmin software RAID1 after adding two 4 TB M2. SSDs, the rest of the system remaining the same. The system also has one additional internal and one external harddisk but these should not be touched. The system will continue to run C7. If I remember correctly, the existing SSD does not use a M2. slot so they

https://www.asrock.com/nettop/index.asp Asrock has a series of Intel and/or AMD based mini-pc's called the DeskMini. Competes in the Intel NUC space. Plenty of power and up-to-date components, multiple ports for dual monitor and at least two ssd's, etc. I don't work for Asrock or sell their equipment.

My computer running CentOS 7 is configured to use BIOS RAID0 and has two identical SSDs which are also encrypted. I had a crash the other day and due to a bug in the operating system update, I am unable to boot the system in RAID mode since dracut does not recognize the disks in grub. After modifying the grub command line I am able to boot the system from one of the harddisks after entering the

nice time, Xen community. my DomU has very slow Disk performance, despite the usage of SSD''s. Maybe somebody can give some good tips to accelerate, or point out my mistakes.

Hi, I once again have a problem with memdisk failing to boot a harddisk image to update my Thinkpad X200s firmware. I extracted the harddisk image from the eltorito type 4 ISO using the isobar tool. Then I added memdisk using this image as initrd to my grub, rebooted and it boots into PC DOS and then freezes (ctrl-alt-del still works to reboot the system). Inside Qemu however it works fine

At the present moment, my guest is running inside qemu and host is kvm intel, running Ubuntu 14.04, kernel is 4.3.0 stable. From within the guest, when I run "hdparm -i /dev/sdb" on the guest, I get: HDIO_GET_IDENTITY failed: Invalid argument as the error,but on the host, I will get the full harddisk/SSD info. Can I know how to resolve this so that the output is the same for both

I tried moving a PosgreSQL database to an external harddisk due to lack of space on the main harddisks. Not the ideal solution of course but it should work.

Hi, I have 4 x 500GB PATA Harddisk and I like to have them striped and mirrored. What is the best practise? Raid 0+1 or 1+0.. And how do i go about it? Thanks

I'm running into an issue which I didn't expect to encounter. When specifying the "nopassany" parameter to hide physical drives, I'm getting different output from ELTORITO.SYS (v1.5, syslinux distro) such that it fails. My intent is a LiveCD functionality with a DOS RAMDISK program taking over as drive C:, meaning either no FAT partitions on harddisks and removable disks

How does one put centos on a laptop? My understanding that laptops no longer come with optical drives.

Hi, I'm experiencing recently happend kernel panics while making bacula backups on my external USB harddisk. It first happened some days ago while I was running 6.4-PRERLEASE. I then updated to 6.4-STABLE and enabled all the kernel debugging stuff. I've uploaded "screenshots" (including backtrace) here: http://pics.pofo.de/gallery/v/misc/ I'm now not sure if the external

I'm having loads of problems with recordings, as in crappy audio quality and lost pieces of the recordings. I've been searching for a solution and the solutions i find on the interwebs include a ramdisk, for local recording, or another machine, handling the recording. I guess the ramdisk would be the "easy" solution and the external machine would be little harder to set up. I do

I don't know whether testdisk would be helpful in this case or not but your options are limited, might give it a try. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of H <agents at meddatainc.com> Sent: Friday, October 2, 2020 6:40 AM To: CentOS mailing list <centos at centos.org> Subject: [EXTERNAL] Re: [CentOS] External harddisk
