maybe cacti and co is too complicated and looks a little outdated… collectd might be just what you are looking for 🙂 „The main objective of this is to develop an easy to use and customizable web interface for Collectd […]

The Enterprise Volume Management System (EVMS) Project has the goal of providing unparalleled flexibility and extensibility in managing storage. It represents a new approach to logical volume management for Linux. The architecture introduces a plug-in model that allows for easy […]

you should setup harddisk encryption during setup. to add an encrypted /home partition afterwards might be possible but a lot more effort. scroll very down if you want to know how to encrypt an usb sticks … needless to say […]

harddisks… are blackboxes of data – if something fails… you do not repair – you replace. 65% of all harddisk failurs can be announced with smart. wohoo! so don’t rely on it 😀 apt-get install smartmontools # some commands smartctl […]

btrfs is used by SUSE12 for the /root partition – where it is doing daily snapshots of the installed OS. It has more functionality built-in than just storing files. This article wants to take btrfs for a test-drive. Video Tutorials: […]

As we all know… if you accidentally deleted a file… you better have a working backup. If not: Try to do as less write access as possible to the disk – turn off PC and boot from Live-CD-USB-Stick such as […]

can be easily checked via: root@debian9:~# cat /proc/filesystems nodev sysfs nodev rootfs nodev ramfs nodev bdev nodev proc nodev cpuset nodev cgroup nodev cgroup2 nodev tmpfs nodev devtmpfs nodev debugfs nodev tracefs nodev securityfs nodev sockfs nodev bpf nodev pipefs […]

iSCSI it is possible to tunnel SCSI through TCP/IP – allowing adding ressources of storage-servers directly – as if it was a local harddisk or partition. The isci-initiator (client) can „partition-and-format-over-network“ the iscis-target (harddisks or files acting as aprtitions on […]

The good news is: It supports OSX and Linux now. Windows & Linux Servers Microsoft Exchange, Microsoft SQL, SharePoint & Active Directory Microsoft Azure & Amazon EC2 cloud workloads Adding a machine running Windows Adding a machine running Linux Adding […]

in general backup! backup! backup! before fiddeling with partitions and the filesystem… logical volumes basically allow you to span partitions over several disks/partitions as well as resize those partitions. windows calls this „dynamic partitions“. it will take some practice to get […]

there is an confusing amount of programs under linux that can do partitions – it is not really clear – when you need what or if you need them at all. this article should get you some info if you […]

yeah i know i sometimes make fun of distributions that have like a partition for every /root/folder but well yes it has it’s reasons. suse12 uname -a; # tested with Linux suse 4.4.21-69-default #1 SMP Tue Oct 25 10:58:20 UTC […]

the commands used for xfs are different. this is only valid for ext3/ext4. preparation: you should move your /home to a separate partition. Warning! You will need to have „physical“ access to the server’s console in order to perform these […]

„XFS is a high performance journaling filesystem which originated on the SGI IRIX platform.“ SGI (Silicon Graphics) is out of business since 2009. „The addition of 3D graphic capabilities to PCs, and the ability of clusters of Linux– and BSD-based […]

backups of a life system under linux – many answers and almost a science of itself. i guess you will have to try a handful of them out to see if they work for you and fit your needs. this […]

this is a crowd-funding project that still needs funding…. if you can help! please chip in 🙂 https://www.crowdsupply.com/gnubee/personal-cloud-1 Tour of LibreCMC and openmediavault We took a screencast of LibreCMC and some screenshots of openmediavault running on the GnuBee Personal Cloud […]

MY RECOMMENDATION: WHO CARES IF THE NAS IS DOING A AUTOMATIC REBOOT AT SUNDAY 3 o’CLOCK IN THE MORNING AND CHECKING 2-3TB OF EXT3 FILESYSTEM? NO ONE! RELIABILITY SHOULD BE THE TOP1 PRIORITY OF ANY FILESYSTEM. MAYBE SPEED CAN BE […]

TESTED and Worked! with acronis 2015 usb boot stick. !!! BE CAREFUL YOU DON’T WANT TO OVERWRITE ANY INTERAL HARDDISK HERE!!!   find out where your USB Stick is-mounted… you could use gparted which gives you a nice grafical view […]

to mount a NFS share on boot you need to specify it in /etc/fstab (/etc/init.d/rc.local -> script did not work for me in debian-jessie) apt-get install nfs-common; # install basic software needed to mount nfs sudo vim /etc/fstab # add […]

We are talking about that piece of hardware: while this is a neat idea… i had trouble getting NFS compiled into the image/kernel… but up to that point, things worked pretty well 😀 another thing is: to rely on the […]

what to do? manually check filesystem: I recommend you to run this in a screen -S FileSystemCheck session, so it will keep running if you get disconnected. 1. determine the name of your raid device (usually md0) cat /etc/mdadm.conf ARRAY […]

Enable SSH Access via SSH and login as the admin user with whatever that password is /etc/init.d/StartMediaService.sh stop And then disable the services by editing that file: vim /etc/init.d/StartMediaService.sh modify the line starting with MULTIMEDIA_PATH and set it to = […]

what use is it if one disk fails… and half of the swap area goes lost and you can not resync the disks because some system-processes are failing…. # switch off swap space swapoff -a # check out what software […]

watch in HD 🙂 DO NOT CREATE SWAP AS RAID0! (you gonna want more stability and less performance: how to change swap from raid0 to raid1) follow this guide to get full blown Debian on your kirkwood QNAP NAS: http://www.cyrius.com/debian/kirkwood/qnap/ts-219/install/ 1. […]

let me be clear: some time ago… i lost a ext4 filesystem on a prosumer QNAP nas…. (the taiwaneese are packing too much software on those things anyway – it is not supposed to fly to the moon – just […]

when a harddisk goes bad, i thought that the filesystem is marking the bad blocks as „bad“ and using other blocks. never the lass i had the case where one samsung disk started having 2 bad blocks going undetected. now […]

pretty amazing 😀 BUT ONLY WORKS PROPERLY WITH EXT3! NOT EXT4 🙁 i managed to recover *.aac files that i accidentally deleted with rm -rf ‚*(1)*‘ (!!!!! YOU NEED TO ESCAPE THOSE \( \) OR YOU WILL STAND THERE WITH […]
