ANNOUNCE mhvtl-1.2-1

[Mark Harvey]

I'm posting mhvtl-2012-01-21.tgz / mhvtl-1.2-1

The major difference between this and 1.1-1 is the inclusion of lzo compression libraries.

Now the user has the ability to select lzo or zlib compression libraries dynamically.
Either via
 - the device.conf file using " Compression type: lzo" or "Compression type: zlib" per tape device entry
or
 - using 'vtlcmd <> compression lzo' or 'vtlcmd <> compression zlib'

note: A mhvtl-1.2-0 never made it out the door due to a late bug report which caused a memory leak on decompressing lzo data.

The format of the 'real time' data has changed to include timestamps for each entry.

The packages are here for convenience.
mhvtl-1.2-1.i586.rpm
mhvtl-1.2-1.x86_64.rpm
mhvtl-1.2-1.src.rpm
mhvtl-2012-01-21.tgz

As always, I'm interested in hearing about any feedback (good or bad).

Cheers
Mark

Compilation Error ... Exitting ...
====================

I did try it both manually and from web console.

Version 1.1, however, installs fine.

As it's vtltape that is failing to compile, I would guess that you don't have lzo-devel packages installed.

Strange the actual compile commands are not being shown.

Hope this helps.

Hi Mark,

You were right.

The lzo and lzo-devel packages are not available in CentOS 5.7, but I installed them from repoforge and the update to 1.2-1 went fine after.

Thanks,
Dragos
