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 have a server with 2 harddisks, configured a one logical LVM block. I would like to reduce the total footprint and remove the 2nd harddisk.
What is the best way to do this? I understand that Gparted has yet to support LVM.
My details as follows:
[root@localhost ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
282G 11G 257G 4% /
/dev/sda3 99M 12M 82M 13% /boot

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.

View 2 Replies View RelatedI 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.)
I need to create a temporary Filesystem and the only way to do it is to reduce /var and create a new filesystem 3GB size
Code:
df -h
/dev/mapper/VolGroup00-var
9.7G 1.5G 7.8G 16% /var
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.
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?

View 3 Replies View RelatedCan 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!
I have the following HDDs in an LVM2 configuration on an F10 box running Mythtv :-
# pvscan
PV /dev/sda2 VG VolGroup00 lvm2 [297.88 GB / 0 free]
PV /dev/sdd1 VG VolGroup00 lvm2 [931.50 GB / 0 free]
PV /dev/sdb1 VG VolGroup00 lvm2 [298.06 GB / 0 free]
PV /dev/sdc1 VG VolGroup00 lvm2 [931.50 GB / 0 free]
Total: 4 [2.40 TB] / in use: 4 [2.40 TB] / in no VG: 0 [0 ]
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 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

a client brought in an 160GB external HDD and wanted to get the files off it, there appeared to be no partitions on the disk but i thought it may have been formatted to use the whole disk. I tried to mount it as the various FS types the client thought it may have been to no avail.
I ran testdisk on it which told me that it previously had a mac partition table and a 210GB partition on it (which is larger than the disk) could anyone enlighten me as to whether or not this is even possible, and if so how could i retrieve the data?
reducing the size of LVM. I did it by using the commands, lvreduce,fsck,resize2fs.After reducing the lvm size, my system is not booting...it is saying file system corrupted error.
