Hi, I'd like to use a flash drive as a journal device, with the purpose of keeping the main disk drive spun down as long as possible. I have a couple of questions: 1) Does the journaling code spread write accesses to the journal device evenly, as I hope, or are there blocks that are particularly "hot"? I.e., do I have to worry about the flash device dying quickly because of

Dear penguin lovers, =) I'm running Linux (2.6) on a satellite receiver with harddrive. The latter is formated in ext3. So far, everthing works fine. Now here's the small problem: The receiver is in the same room I sleep in and when it records at night time I can hear the journaling going on (heads clicking - even though the HD is set to silent mode via hdparm). This is surely due to the

A few wild ideas/questions : 1) Is there a way to check the size of the journal of an ext3 filesystem ? I mean - the actually used size ; not the total size of the journal. 2) Would it be difficult to implement "freeze" of ext3 filesystem - that is, blocking all I/O to the filesystem until it's "unfrozen" (XFS can do that), for two purposes : A/ allowing

Hello, I was not happy with the power consumption of CentOS 6 x86_64 on a new Lenovo Thinkpad x220 Tablet and I worked on reducing it.

As per http://www.williambrownstreet.net/blog/?p=387, add the following kernel arguments to the GRUB boot configuration: pcie_aspm=force
