General :: .snapshot Filling The Nfs Disk?

Jul 19, 2010

I have a lot of data on a nfs store external to an Ubuntu machine. I've had problems with the storage becoming full and have spent a very long time deleting files to get absolutely nowhere! Over 25GB of deletions on the 80GB disk has only cleared 1.5GB of space...

You can see below the hidden .snapshot directory, the disk usage for the nfs-store is coming out at 97GB when the disk is only 80GB in size, and the two directories I want on the disk are about 22GB in size.The .snapshot directory appears to have been made on Friday, I'd like to know if I can:

1) find out what command ran to create/update it

2) re-run the command to update the directory or remove the directory

Code:

ideasadmin@ideasadmin-desktop:/nfs-store$ ls -la
total 20
drwxr-xr-x 5 500 500 4096 2010-07-16 17:35 .

[code]......

General :: Full System Clone Snapshot Using Rsync?

Dec 11, 2010

I have automated backups running on my ubuntu box using rsnapshot (rsync) basically following this tutorial. My concern is how to restore if everything is lost. Since it does not seem that I can backup the entire drive and that I have to choose individual folders and some like proc/ cause problems.

Currently in my rsnapshot.conf I have (see below). Is there a way to just clone the entire drive? Or should I not do this? Questions:

1, Can I backup in a way such that it is a clone of the drive so that it can be swapped with the current drive?

2, If not yes to clone, If I had a total drive failure would I install a basic ubuntu and then replace all the files with the backups?

3, Anything I might not know about that I should.

General :: Copy - Take A Snapshot Of A Directory As It Was At A Particular Point In Time?

Mar 4, 2011

I have a directory containing a lot of result log files (directory size ~ 4GB), and a set of processes running that keep on writing to these files. To be able to correctly analyze the results at a later time, I want to copy the whole directory to an archive destination, and I cannot stop the processes.

I want a copy of the directory as it was at a particular point of time. As the size directory is huge (which means it takes about 40 seconds to copy) and some of the files are being written to, a normal cp -r does NOT give me a snapshot at a particular point in time, rather a snapshot of files spread over some 40 seconds. This is not good enough.

Is there a way to get an exclusive lock on the directory and all its components while copying?

General :: VMware Snapshot With VMware Tools Loses Network On Restart - Host XP - Guest Fedora

Oct 3, 2010

I have been using VMware Player for some time to host Fedora VMware images on Windows XP. I have been using Fedora 11 and 12 (both 32 and 64 bit) and recently started to use Fedora 13.

I use as a base the images provided by thoughtpolice. http://www.thoughtpolice.co.uk/

I usually install VMware tools and also keep the images updated (yum update) which sometimes changes the kernel.

I have recently had problems with the snapshots not having a network when I restore them. So far I don't have the problem with Fedora 11 and do have it with Fedora 12 (but used not to). I do have it with Fedora 13.

In each case the problem goes away when I uninstall the VMware tools and comes back when I install them again.

One of the symptoms is that SElinux complains about not being able to do something with /var/run/vmware-active-nics.

It looks to me that something is incorrect in the actions being taken when the snapshot is being restored. It does not happen every time and sometimes the network restores itself.

The network can be restored by rebooting the image.

Ubuntu :: Take A Snapshot Of My Installation?

Oct 14, 2010

Just lost my harddrive. Bought a new one, installing Ubuntu 10.10. I would like to installa a couple of programs after my installation, wanting to use the machine to develop programs - so I am going to install Eclipse and Glassfish and tomcat and such.

When I am done with that I would like to take some kind of snapshot and burn to a disc. So if a crash comes visiting me again, then I am able to install my basics. This would save me from those boring moments in live.

Can I take a 'snapshot' of my installation, Could I then restore this in some easy way ?

Debian :: Can't Get Snapshot To Work Correctly?

Dec 22, 2010

I started to use Debian Live about three months ago. I can't get snapshot to work correctly. Each time the system boots or shutdown, the system over-writes the persistent file. I'm currently have to use the live-snapshot command to make a snapshot. Make a copy of the file for a backup. Then I have to boot my system and make a copy of the backup and rename the file the correctly. Turn off my laptop (not shutdown). then restart it for the persistent to work. Must be a easier way.I have three partitions: debian-live (/dev/sdb1), live-sn(/dev/sdb2), and home-rw (/dev/sdb3) on a 8 gig usb flash drive.

Ubuntu :: Hangs Up When Creating LVM Snapshot Of /root Volume?

Aug 14, 2010

Recently, I've tried to create a snapshot of my /root folder in 10.04 (I remember to have done so a couple of times without trouble).I used the commandHTML Code: Code: lvcreate -L10G -s -n rootsnapshot /dev/server/root Without a hint of HDD activity, Gnome (?) hangs up - I can move the mouse, and the clock is moving on, but I can't click on anything. No HDD activity, and this goes on forever (after a while, the whole system locks up). This happens each time when I try to create a snapshot.

OpenSUSE :: Virtual Machine Manager Vs. Qemu-kvm Commandline ( Tap Xor Snapshot )?

Mar 28, 2011

I want to experiment with pacemaker, and for that I'd like to start kvm virtual machines with the snapshot option, so that as soon as I stop the vm, all changes are gone and I can start over. Since I couldn't figure out how to setup networking (vm - vm and vm - public) with a kvm commandline without disturbing the Network Manager, I used the Virtual Machine Manager (VMM) for this.

It works now, but I cant see how to use the snapshot option with the VMM. On the other hand, I cant see how I start the resulting vm from the commandline. When I look at the process list, I see the command with these network options:

Code:
-netdev tap,fd=21,id=hostnet0
-device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:45:30:b0,bus=pci.0,addr=0x3
-netdev tap,fd=22,id=hostnet1
-device virtio-net-pci,netdev=hostnet1,id=net1,mac=52:54:00:84:5b:bc,bus=pci.0,addr=0x6

How would I go about these fd=nn things on the commandline? I guess I somehow have to start the tap devices before, but how?

CentOS 5 :: Kernel Panic Creating LVM Snapshot Of Root Fs Volume

Oct 29, 2009

I can cause the kernel to panic immediately with the following command. lvcreate --snapshot --name Snap --extents 100%FREE VolGroup00/LogVol00 The last line of the panic message is "<0>Kernel panic - not syncing: Fatal exception" If I create a snapshot of any other volume it works just fine. It only panics on LogVol00 which is my root fs.

I'm running 5.4 after update from 5.3. It didn't work with 5.3 either. This is a 32-bit guest running in VMWare Server 2.0.1 which is running on FC10 x86_64. I've tried the guest in both UP and SMP (2 cores) modes and observed no difference.
