    comment List File Space Ownership By User
    Interesting, but no. Quota tools tell me how much disk space I am using, I need to know where in the mess those files actually are. Both of those examples appear to brute-force quota replacements; I'm interested in the details.

    Sorry, perhaps I'm unclear. I have to NIS servers, one master and one slave. How do I tell client X that it has access to two NIS servers?

    ...and yes, I'm aware of tripping the irony-detector by using "NIS" and "security" in the same post. The reasons are stupid, but I still have to deal with them.

    comment Does LVM impact performance?
    @hildred, the above is what I was referring to -- I am not aware of any tools that can recover data from a LVM that spans multiple disks (block devices) with one disk missing.

    comment Does LVM impact performance?
    @user13719: yes, you can LVM any block device, but in practice people don't do this. They end up with a single drive LVM'd. Then they add another drive, and use LVM to extend the existing file system onto the new disk. At that point, the failure of either disk will kill the LVM.

    comment What does a high load with an empty top mean?
    The results of iostat -kx 10 show that the disks are not busy. It does appear that these processes are blocked on nfs somehow. @StephaneChazelas, if you write your comment as an answer I'll accept it.

    Have not checked, but I would presume in that case that the [%wa] (ie, wait-on-io) parameter would be non-trivial at that point?

    I would presume the [%wa] field would be high in that case?

    OK, is there a way to determine why they are in the uninteruptable state and what I should do about them?

    comment What makes CentOS “enterprisey” compared to “generic” distributions like Ubuntu?
    @Warren true, but I built on RHEL for stability, not VMware for currency. The lure of RHEL was no major changes -- and they failed. The fact that I got caught up in VMware's marketeering as a side-effect is irrelevant to me.

    comment Need advice to install Unix-like OS on my Laptop
    @Behrooz When it comes to driving hardware, crappy Windows drivers can provide a result better than that provided by total lack of support in Linux. On a platform that is well supported by both Linux and Windows, I agree -- Linux usually wins hands down. But laptops, especially current, high-power laptops, have been known to be poorly supported by Linux.
