/var/log/debug gets lots of messages any time an LVM snapshot is setup (lvcreate --size ${size}k --snapshot --name "$LVM_snapshot_device" "$LVM_device"). Here is a recent sample.
Code:

I have the need to have jack running without any verbose debug message in the terminal, everytime. My system is ubuntu-based.

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.
so i have f12 installed on my hd with lvm using the whole extent of the HD , i want to reduce it so i can dual boot it with a windows system, i managed to reduce the logical volume to free some space, but i cant seem to reduce the physical volume, is this possible and how ?

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 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 need debug my program and I need something like a virtual microphone. I would like device "microphone" where I can put sound file and this file will be input for microphone stream. And in application I get this stream from this "microphone"

something like bash command should by very very useful:

The thing I have is a Makefile with different rules that I compile like this:

What I would like is to add an option so I can compile whichever module with debug-information just by adding a debug to the make command. The debug-information I know how to do, the problem is how to make the Makefile work...

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?
View 1 Replies View RelatedI have a working build of crosstool - it was built for gcc 3.4.3 using glibc 2.3.5 going from 32-bit x86 linux to 64-bit alpha linux. As far as I can tell -- it compiles correctly (output of alpha emulation matches expected) but it has a major flaw. When I use the cross compiler and attempt to add detailed debug information, it compiles, but does not have the debug information. For example, when I execute:
> /home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc-3.4.3 -g -o hello main.c
OR
> /home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-gcc-3.4.3 -gstabs -o hello main.c
I get a working alpha binary for hello world. BUT - when I run objdump - this is what I get
> /home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-objdump -g hello
hello: file format elf64-alpha
/home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-objdump: hello: no recognized debugging information
Frustratingly - if I use my x86 gcc version 3.4.6 to do the compilation (same arguments, just using the x86 compiler, not the cross compiler) - it correctly embeds the debug information.

I have a syslog-ng running and kernel build of 2.6.34.8 I use a syslog API in my program with facility LOG_LOCAL5 and and levels debug err and crit and info. when I ran on the older syslog facility I had everything logged fine as I intended. now I have written these rules into the syslog-ng.conf:
options {
flush_lines (0);
time_reopen (10);
log_fifo_size (1000);
[code]....
the last two rules show my program gnssapp. the result is all debug levels or crit or err levels I don't see any of them !
I've developed a tiny webserver for home automation out of an ALIX 1D, and based on a debian lenny. It runs very smoothly and is now able to operate quite a lot of different equipment from a webapp. But i'm not sure how I should handle the compact flash, regarding read/write limitations. From what I've read the partitioning should be ext2, which would disallow the journalisation of the system. A utility to 'flatten' the repartition of write cycles exists, would it be relevant to use if the partition is ext2 ?
I will also disable all logging in execution mode (a debug mode will provide the logs). Is there any other parameters I have to take into account for maximum reliability (i.e. does the system randomly write in some files for various and potentially turned off purposes)? As for the mysql database, it's not important data, and it's actually reconstructed every time the server boots. Given this, is there a way to store the db in RAM rather than in a file? I'm not sure it's the right place to ask, but I sometimes see redirection to here from stack overflow.
