I have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive
- the first partition is only 64MB; - the second is a large 900GB partition and - the last holds all the remaining space
mdadm has been used to set up /dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1 /dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2 /dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3
OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.
On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.
I'm all new to linux. I've got Fedora core 12 - I'm ex windows user. I have these 3 websites to maintain: These are in finnish language. So called pikalaina sites: pikalainat pikavipit vipit
And I have to add pictures to these pages. I don't know how to do even that I don't know web programming or HTML. But my images are about 1 mb in file size - I use to have windows and photoshop and there is this save for web feature where file size is reduced.I have this GIMP -program now - it's terrible compared to photoshop, but it's free. In GIMP there is no feature how to reduce file size for ex. 1mb to 20 Kb. How do I do this? Do you know any good program to do it?
My laptop has 2Gb of ram, 4Gb of swap, 40Gb hdd and an intel pentium 1.40GHz cpu, even when compiling stuff or maxing out everything the 4Gb of swap is never touched, with such a small hdd I'd like to reduce the swap to about 2Gb (just in case) to free up some space, does anyone know what commands/tools are available to accomplish this?
The icons in the applications pane are very big, I need to scroll multiple times inorder to reach the last program. How to reduce the icon size, so that all the installed programs can be visualized without to much scrolling?
I'm new to Fedora 14, vmware player. After getting Fedora up and running in VMware player. The disk size was 2.7 GB. After three hours of working with it, the disk size has bloated to 4.3 GB. I havent added software to account for the near doubling in size. How do I reduce the size back to 2.7GB range or lower. Im new to Fedora and superuser controls. Im removing more software than adding software. Is this a VMWARE problem or Fedora problem?
I have a home directory which is mounted on the LVM partition,How can i reduce the size of LVM partiotion without loosing the data on home directory...whenever i use lvreduce command it show me a warning mesg that the whole data will be lost...reducing the size of LVM partition without loosing my home directory data.
Using KInfoCenter | Memory module it shows my 2GB of ram. Approx. 14% is used for Application Data and Disk Cache has been anywhere from 29-35%...leaving approx 1GB free. Can this 'Disk Cache" be reduced leaving more memory free or is this determined by the OS?
i m using ubuntu 10.4 version and i want to knw that is their any software or something else so that i can resize my images from 2 mb to in kb as my image folder is of 614 mb and i want to put that folder images in my mobile so how can i reduce the size of that folder
I was cloned an entire disk (with one NTFS partition of 70GB, only 15GB used) using ddrescue with the following command...
Code: ddrescue --no-split /dev/sda /media/usb250/ntfs.img /media/usb250/ntfs.log The img file it's around 70GB. Now I want to restore it to another computer with 30GB of space. How can I reduce the size of img file?
I'm new to Ubuntu Netbook Remix. I love it. I'm using it for web dev with a LAMP and Rails installed. Everything is peachy.I would much prefer the icons in the launcher to be a lot smaller though, anyone have any idea how to scale them down? I reckon about 75% the size they are now would be about perfect.
I have a HDD that has 2 partitions. the 2nd partition is the VG and I want to reduce its size. I have reduced the Largest LV in the VG and now have free space in the VG. But, I am clueless on how to proceed to reduce the partiton size so that I can use it for another need.
When done, I expect to have 3 parttions total on the HDD. But first, I could some help in understanding the steps necessary for me to take, to move the free space out of the partition that has the Volume Group. Then, i can use fdisk on that 3rd partition for my needs.
I already know how to expand a Volume group by adding PVs, but, I do NOT know and cannot find how to reduce it to recover the free space in the VG to be used in a new partiton. (Better explained..."I want to reduce the physical partition size that the VG represents.)
my question is according to google search I need to umount the filesystem point in order to reduce its size.... so it means I will require that nobody uses the system? since /var logs a lot information?
I also have the option to reduce /root but I think is more complicated.
so what are the precautions in order to reduce /var/?
I installed Debian 8 Jessie with full disk encryption and chose to have everything on the same partition. After install, I notice that my 8GB laptop has a 16GB swap. Is there a way to reduce the swap to 8GB (or maybe 4) whilst not affecting the encryption?
I have a 1TB HDD so space is not an issue but I dislike such waste. The setup used LVM.
I have rendered out less than two minutes of High Definition animation to Avi-Jpeg Format in Blender. Now, I have this 2 GB file. Going at this rate, it's going to take a whole DVD set to play a 15 min movie.
Surely, this file doesn't need 2 GB just for 1:45 min/sec, right? Even at high def? How do I reduce this file size down to like a manageable number, say, 20 miB?
i am looking for an image manipulator that will run on KDE and lets me convert hundreds of jpgs (> 1 MB each) at once into an emailable size like 50-200 kb each, so i do not have to do that for every picture, one by one.
Can the size of the Ubuntu desktop window be reduced so that it displays on a monitor or via a data projector with a surrounding black border? If so, how? The tragicomic chain of events which leads to the question is as follows. Community group, short of cash, want to equip lecture room. Pull-down screen is set up permanently on one wall. Contractor sets up old data projector via ceiling mount. Data projector is just too far away from wall, such that image cannot be reduced sufficiently by the data projector to fit on the screen.
Annoyingly the image, as displayed, is only slightly too large - just enough to lose the top and bottom panels, Applications menu, File Menu on full-size windows, Indicator applet, Trash, and restore desktop button. The data projector is hooked up via VGA cable to a recycled PC running Ubuntu 10.04 with proprietary NVidia driver (version 173) for GeForce 8400 GS. I'll give anything to be able to do this on the PC, rather than having to move the projector!
The system never uses more than about 250GB of HDD at any one time, so I would like to remove /dev/sdd1 and /dev/sdc1 from the LV and then from the machine and leave /dev/sda and /dev/sdb alone.
Does anyone know that if I use the command "system-config-lvm" to reduce the total LVM size to say 580GB, whether all data is preserved (I don't have any way at this stage to backup up 250GB of data, unless I buy more HDDs and that is the whole point of this exercise anyway - remove the two terrabyte drives to be used as backup disks).
Once I am happy that the data is safe, I will use "pvmove" and "vgreduce" to remove both terrabyte drives.
I have been asked to investigate some of our servers that run tripwire 2.3.0 on Red Hat Linux Advanced Server release 2.1AS (Pensacola)
We have the reports emailed to us using cron and twprint -m r -r report -t 4, it has been growing steadily and today it was 9mb It seems the database records go back to before 2004 and are being compared against today's files.
I really need to be informed what needs to be done to tripwire to keep it serviced through cron. I have tried to google this but could not find any information that seemed to answer my questions.
Looking at the following guide url step 6 talks about "Updating the Database after an Integrity Check" using
Code: # tripwire --update --twrfile /var/lib/tripwire/report/<name>.twr Should I be using this command or should I be re-creating the db every month or so and using the #tripwire -init?
