Year 2000 has passed, no flying cars yet but at least more faster (SSD and NVMe) disk space 😀 All sorts of resources also digital resources and bandwidth, RAM and DiskSpace space are STILL precious and should be treated as […]

UNTESTED! 😀 “Micron has been developing some of the world’s most advanced memory technologies for more than 40 years, including DRAM (Dynamic Random Access Memory) and NAND flash memory chips, which are used in a wide range of products, including […]

NTFS (better file exchange since 2021) vs Open Source https://www.theregister.com/2021/10/13/how_ntfs_finally_made_it/ wow. just as the word.doc(x..xx…xxx) formats NTFS kept changing… will it ever “settle”? X-D (currently v3.1) making proper file exchange (without the risk of dataloss) between the Open Source and […]

if the spice tools are installed, clipboard sharing between host and guest (copy & pasting text and even images (!)) should (!) work 😀 What is not working virtualbox-easy-style (yet) is easy-host-to-guest-and-vice-versa-file-transfer (which IS VERY ANNOYING (RedHat are you listening? […]

currently testing the AMD workstation with the KINGSTON SKC3000D2048G NVMe, directly attached to one of the 2x NVMe slots (no RAID), as this NVMe drive seems to offer excellent price-to-disk-size-and-performance-value, if it is a kingston-quality drive, then there should be […]

got a new toy. after the MDADM RAID0 with 2x datacenter capable Kingston directly mounted on the mobo, did not turn out MASSIVE speeds 😀 (it was just a test, what speeds those datacenter (!!! 24-7 operation for years!!!) can […]

what to expect? while x264 and x265 are surely great codecs, the re-encoding of x264 to x265 is very CPU and thus time and energy intense and on preset  -crf 28 + mp3 audio (for material of high importance aac […]

How to create an encrypted USB stick Creating an encrypted USB stick under GNU/Linux is fairly ease. First lets install required packages and erase everything from the stick gives good overview of where is what: (in a tree view style) […]

“to swap, or not to swap, that is the question”: definately swap Shakespeare “to encrypt, or not to encrypt” (if it contains valuable data, encrypt) “to lvm, or not to lvm” (well….) because: one fine day, the user decides to […]

create a new shared folder on the nas call it “data” enable NFSv4, disable NFSv3 specify list of IPs that are allowed to access the NFSv4 share: don’t forget to hit “Apply” the idea is “anyway” to NAS<-directly-LAN-1000MBit->PC connect the […]

IDE, SCSI, SATA, SAS now U.2 M.2… that reminds of… USB Cable Salad of Madness – USB 3.0 and WiFi interference – Micro-USB USB-C mess has finally arrived the list of interfaces grows by the year? no U.2 is not: […]

ZFS is probably THE most controversial filesytem in the known universe: “FOSS means that effort is shared across organizations and lowers maintenance costs significantly” (src: comment by JohnFOSS on itsfoss.com) “Mathematicians have a term for this.  When you rearrange the […]

possible (untested!) alternative: SanDisk Extreme Pro Portable SSD V2 Review the harddisk reliability toplist: while this toplist says nothing about how reliable the harddisk can store and return exact copy of data written (!!!). this has to be tested in […]

nfs is to GNU-Linux what smb is to Windows: sharing dirs & files “The Network File System (NFS) was developed to allow machines to mount a disk partition on a remote machine as if it were a local disk. It […]

making usb sticks with GNU Linux and dd: WARNING! one single wrong drive letter and data could be irreversible destroyed! (it has happened many times before!!!) so this script make_stick.sh (download it here) aim’s to double check if it is […]

raid10 combines the speed of raid0 with the resilience of raid1. watch out: shingled hdd are not good for RAID! setup of GNU Linux mdadm software RAID10 is actually pretty straight forward: no need to do any partitioning. # tested […]

UPDATE: 2022 may have to appoligize to HighPoint and ALTERNATE, as other RAID systems such as the AMD RAIDXpert2 based systems (same concept) are also STALLING during ATTO Disk Benchmark in Direct I/O mode. So the ATTO Benchmark MIGHT be […]

for even better overview, it is possible to label harddisks & partitions like this: # this can be done on mounted ext4 / ext3 / ext2 partitions # swap partitions can not be labeled tune2fs -L “LABEL” /dev/sdaX # with […]

for some reason… did ext3 on RAID1 with two disks (seagate + wd) of different sized (2TB but they (of course) are not exactly 2TB) watch out: shingled hdd are not good for RAID! not sure where the problem here […]

to recover the data: how to mount luks2 encrypted volume also check out alternative: GNU Linux – create new encrypted partition harddisk – how to open encrypted harddisk partition possibility: remove harddisk, attach to sata2usb adapter, then mount on different […]

btw: love kvm (used by very large companies) just as virtualbox (oracle) the task: over the years a windows vm is using up massive amounts of precious server harddisk space (snapshots before everyupdate) all the snapshots now add up to […]

update 2022: next to the good old (non-destructive if used correctly) “dd” is still the way to go for benchmarking harddisks under GNU Linux. a simpler one is “gnome-disk-utility” also interesting but not very simple in installation & usage (complicated! […]

apt update apt upgrade is what users do… having no idea of the “heart attack” momentum that is awaiting them X-D after a reboot… and 1min 30sec timeout, the dreaded Control+D give root password prompt appears. “Houston we have a […]
