Hi, I am using CentOS 6.4. uname -r gives me
3.9.3-x86_64 Kernel version is 2.6.32. My questions -
What is 3.9? In Ubuntu, uname -r and /boot give the same version numbers.
Do we have a mapping of CentOS versions, the numbers like 3.9 and kernel versions maintained somewhere?
Regards,
Jayadevan

Please show us the output returned by:
rpm -qa kernel* | sort
That should give us some clue.

3.9.3 is the kernel number. All Linux distributions use the Linux kernel, so Debian version X and CentOS version Y may use the same kernel as may Ubuntu version Z. There may be a list of CentOS versions and kernel numbers somewhere, but I can't see that it would be of great interest.
My Ubuntu 13.10 shows 3.11.0 so you have a fairly old Ubuntu version there. In general the Ubuntu kernel will be newer than the more conservative CentOS/RHEL.

CentOS 6.5 doesn't ship with a 3.x kernel. If it was a 2.6.32-something kernel then it would likely be an official kernel ... not a 3.x though. Possibly from elrepo or another third party repo.
That's why this might be of interest to the OP.

Ah, right. I was assuming (maybe erroneously) that the OP knew what was on his/her system. 8-)

Your current running kernel version is 3.9.3. Someone has installed a kernel from a source other than the base CentOS repository and booted it. You may have 2.6.32 installed somewhere on this box, but it wasn't used for this boot.
What is 3.9? In Ubuntu, uname -r and /boot give the same version numbers.
/boot is not authoritative for the running kernel, because /boot can hold many different kernels (or really anything you put there). uname is authoritative for the current running kernel, and grub is (mostly) authoritative for the kernels available on the next boot.

You can look in the vault:
Keep in mind that there may be more than one distributed kernel for a given CentOS release, since there are updates to packages as well.
