comment Resizing LVM within a in KVM-based VPS
You don't want to create a second pv on the same disk; you just want to grow the existing pv.

comment What is the difference between /dev/sda and /dev/hda?
Linux has treated IDE drives as scsi and hdx has been unused for a decade or so.

comment What is the difference between /dev/sda and /dev/hda?
If by "sometimes" you mean when you run a linux kernel from 10+ years ago...

comment What file system should a GRUB 2 boot partition use?
Having a separate /boot partition is an anachronism from days gone by, where it was common for the bios to not be able to access the whole disk, or before grub2 gained the ability to recognize just about any filesystem. It is no longer needed or recommended. You also can use xfs just fine; the error you got is from trying to install grub to the partition instead of the MBR, which you should not be doing with any filesystem.

comment mount: warning: /etc/mtab is not writable (e.g. read-only filesystem)
Looks like it is only a single bad sector, so likely he just lost power in the middle of a write or something like that to corrupt it and the disk is fine. A fsck likely will fix it, otherwise forcing a write to the affected sector with dd will.

comment Is there any DLP solution for linux?
This term appears to be a made up marking B.S. by firms selling snakeoil designed to separate fools from their money.

comment How to detect real sample size and number of channels in WAV file?
In that case neither my comment, nor the question make sense since there is no relationship between sample size + rate, and the bit rate of a lossy compressor.

comment mount: warning: /etc/mtab is not writable (e.g. read-only filesystem)
Because a ram error isn't able to change the bits in the sata registers to indicate a media error.

The error is specific enough that this is a cut and dry bad sector. No need to monkey around with memtest or checking cables; go straight to smartctl.

If mplayer didn't notice it was really dts though, you would just hear noise.

There are two channels, hence it takes twice the bandwidth of a single channel.

comment Size Range of ext4 Filesystem Journal
It seems the limit was increased to 10,240,000 blocks for both ext3 and ext4, though the man page for tune2fs hasn't been updated ( the man page for mke2fs has ).

comment How do I get LILO to boot on cloned hard drive?
The ancient kernel being booted will still recognize the drive as hda, so the root setting needs to stay as that, and only the boot setting needs to point to sda while reinstalling lilo from the livecd.

comment Size Range of ext4 Filesystem Journal
The same; ext4 is ext3, plus a few additional options enabled.

comment tar & gzip the same folder but get different size
md5sums will give a hash of each file. If the file of the same name in the other directory has a different hash, then its contents are different. As @Giles pointed out, even if the contents are the same, the ownership and timestamps may differ, which would cause the tar to differ. @Hauke Laging, the reason it is off topic is because the problem is due to user error: the two folders are in fact, not identical.

Then the folders are in fact, not identical. Use md5sums and you should find some files have different contents.

comment Internal Socket Receive Buffer Implementation
What makes you think you should be using a ring buffer? And if it's your buffer you can "flush" it ( what does that even mean in this context? ) any way you want. The kind of application you describe should just be in a loop recv()ing a packet, parsing the data, and repeat. No fancy buffering needed.
