Is Esxi Var/log pointing to scratch partition?
If yes all the logs in var/log folder(hostd, vpxa, fdm etc) will be deleted after the esxi reboot if scratch partition is on RAM disk?
If you have not configured scratch partition , the logs will be in RAM disk and it will be deleted post reboot of ESXi.
The below article will help you configure scratch location on ESXi

After installing proxmox onto my server hardware, it seems that just a few gb of disk capacity are available to use, but I don't know why.
The proxmox configuration happened the following way:
Hardware RAID Level 1 configured to mirror the first and second 1TB hard drives
Within the proxmox install wizard, I configured the server to use those disk and create a LVM
This LVM is showing up in the gui, but it has just 16 GB left of capacity, did not an option to do disk partitioning on install more specifically
What am I doing wrong or overlooking?
Proxmox LVM is thick provisioned. Log in per ssh and run "df -h" to see your disk usage. You can expand your LVM config (lvextend /dev/pve/data).
Here you have more details: Proxmox Wiki, look at "Advanced LVM Configuration Options"
I always install Proxmox like this:
LV root: 50G
LV data: 50G
But i've an external storage for VM storage.
I have a linux VM running some processes. I want to pause these processes, shut down my VM and boot this VM on a different machine in such a way that all the previously running processes resume execution from the last state before the VM was shut down. Is this possible ? If yes, how can I achieve this ?
Can hibernation help me achieve this ?
First off, What's the hardware?
What host os you using like windows?
What software are you using for the virtual machine?
Where is linux booting off, is it a vmk file?
What kind of storage are you using and have you direct access to it?
You haven't given much information to go by to give exact step by step instructions.
My personal use I have found that it is possible to boot a physical drive with virtualbox, my drive also has a ntfs partition on it but the drive has to be offline on windows for me to boot and have administrator privileges which does not allow access from windows to that partition, if you are only using one physical hard drive I believe this may not be possible or may cause serious failures. If you have another hard drive you can copy the system over to a partition with enough knowledge. Here is a reference from the arch linux wiki
Oh and about hibernation I haven't used but you can read up about acpid
and having the virtual machine software to pass the event on
My setup is I have two NAS setup. I can mount those NAS in a Linux Server (Ubuntu or Centos) and plan on writing on both NAS synchronously or replicate frmo one nas to the other one real-time.
Anyone have any ideas how can i do this? I've been looking at glusterfs but is there any other option i can use?
Thanks alot for the help.
I had windows operating system. I have installed Ubuntu 14.04 operating system by over writing windows 8. But I lost 5 GB of data which was very important.
I tried test disk tool to recover data.But it couldn't recover the data.
testdisk
kindly help to solve this problem.
Is it possible for a linux data recovery tool to recover data from NTFS partition?
thanks in advance
If you installed Ubuntu right on top the W8 partition the chances are high that some of that data is lost.
Before you do much and destroy even more data:
1)Get yourself another machine.
2) Attach the disk to it and copy it with DD as backup or for extraction purposes
3) Mount the Copy and analyze it with SleuthKit and Autopsy.

I need to test a program on SmartOS. I don't have any spare systems lying around so I wanted to install it into a KVM image on my GNU/Linux distribution. I've installed Solaris 11 that way and that worked pretty well.
I downloaded the ISO and booted it inside KVM and the installation appeared to work fine. However when I boot the virtual machine it always starts to come up and says:
Booting from harddisk ...
and then it just sits there, with the virtual CPU pegged, and never proceeds any further. No key presses appear to do anything (except Ctrl-Alt-Del which starts the boot again, giving the same result).
I created my KVM from virt-manager with 2G RAM, 2 CPUs, 50G of disk space using a "raw" disk format, and selected "Solaris" / "OpenSolaris" as the OS type.
I don't have a copy of VMWare and it seems really expensive to get one for Linux, so I don't think using the SmartOS VMWare image is an option for me.
Anyone have any hints? Google shows me lots of information about creating Linux instances inside SmartOS KVMs, but nothing on doing it the other way.
I figured it out with some help from the mailing list. SmartOS is a PXE booting operating system: it doesn't actually install to the harddisk. When my installation was complete and the VM rebooted KVM automatically unmounted the ISO file from my virtual CDROM, so on boot it was looking for a PXE image to boot from and couldn't find it.
All I had to do was re-attach the ISO file to the virtual CDROM and it worked fine after that. Ugh.
