I'm having a problem with my LVM volume. I lost a disk out of my RAID array, and started in in degraded mode. Now when I try to access 2 of the LVM volumes, they report a block size of 0. Does anyone know what is going on?

$ lvdisplay
--- Logical volume ---
LV Name             /dev/vg0/home
VG Name             vg0
...
LV Size             20.00 GiB

$ blockdev --getsize64 /dev/mapper/vg0-root
0

$ mount /dev/mapper/vg0-root /mnt
mount: /dev/mapper/vg0-root: can't read superblock

$mke2fs -n /dev/mapper/vg0-root
mke2fs 1.41-14 (22-Dec-2010)
mke2fs: Device size reported to be zero. Invalid partition specified, or
        partition table wasn't reread after running fdisk, due to
        a modified partition being busy and in use. You may need to reboot
        to re-ready your partition table.

Please explain pros/cons when using the different Nginx WSGI interfaces? Please explain in detail what differentiates each configuration? Which configuration should scale the best?

If relevant, what are you running right now, and why?

Some techniques I've seen, but please tell me if I've missed any:

• Mod_wsgi
• uWSGI via Nginx uWSGI
• FastCGI + flup
• Proxy another WSGI Server (gevent, gunicorn, tornado, FAPWS3)

I think I ran across a bug in a batch file because it was written with unix line endings. Is this a known problem with cmd.exe running batch files in windows?

This is a dumb question, but is there a syntax specification for the Apache .htaccess file format?

All I can find are "tutorials", that is not what I want.

What I want is a list of all the valid keywords that will be recognized in a .htaccess file and what all the valid parameters and functions are. Does this exist?

My TinyDNS install on pfSense is only able to resolve local host names. Any external domains, come back as blank. The strange thing, is that they resolve correctly when SSH'd to the pfSense box. I also want to get the TinyDNS exposed on both LAN and WAN sides. Right now it is just working on LAN side.

Can someone provide the correct pfSense settings for TinyDNS?

I'm interested in an Intel Atom D510 based RAID system. The manufacturer lists the maximum drive limit as 2TB, yet everything I've read says that SATA supports much more than that.

Is the 2TB "limit" based on current 3.5" drive densities, or is there something preventing an Atom system from handling drives larger than 2TB?

I'm trying to shrink a Linux software RAID10 array. I have already shrunk the FS volume. The md volume is 64kb chunks w/ "far" mode. Is it possible to safely shrink the underlying RAID array in someway without having to wipe one drive, copy the data and re-sync?

I can't seem to get CPAN installs working on a Solaris machine. Here is my current output.

~# perl -MCPAN -eshell
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v1.7601)
ReadLine support available (try 'install Bundle::CPAN')

cpan> install Bundle::LWP                 
CPAN: Storable loaded ok
LWP not available
CPAN: Net::FTP loaded ok
Fetching with Net::FTP:
  ftp://ftp.dti.ad.jp/pub/lang/CPAN/authors/01mailrc.txt.gz
Couldn't fetch 01mailrc.txt.gz from ftp.dti.ad.jp
...
...

This output is repeated for every mirror. Any ideas why this doesn't work?

I'm trying to disable log events for the vmware-hostd process on my system. There is a file /etc/vmware/hostd/config.xml that has log level settings.

What are the correct values to disable constant logging to /var/log/vmware/hostd.log?
