Is the Veritas volume manager available for linux? If so has anyone 
tried it and have some comments about it?

Thanks

John

Yes, it is. However, it is very kernel version specific and really provides
very little benefit compared to Linux LVM/MD for the price.

Hi Mark,

Thanks for the info. My impression is that the Veritas VM has a lot more 
features than MD/LVM including management tools, on-line 
reconfiguration, etc. These seem like valuable features. What's the cost 
of VVM?

Thanks

John

You can (and should) always go to the vendor's website and look there,
because this list is not about Veritas products and/or marketing/sales.

Hi Jose,

I am assuming that this list is about linux raid and that the Veritas 
products are raid products on linux. I assume that this list is not 
restricted to discussions about free raid implementations. If I want 
marketing fluff I can get that from the Veritas site but I'm interested 
in why real people would use Veritas on linux or why not. So far it 
seems that the cons are lack of broad support for various linux kernels 
and cost (which is not on the web site) and the pro is a professional 
mature stable product. The current crop of free linux raid tools (MD and 
LVM) seem really primitive and inflexible and having experience with 
Veritas in a previous life on Solaris (where it's really expensive) I 
was wondering if the linux version was as good and whether people felt 
it was worth spending the money to get the Veritas features. Of course 
it's possible that Veritas is overkill for the seemingly limited 
capabilities and application of the current linux PC type systems and of 
course the Veritas stuff might not cover all the possible hardware 
configurations that are available for linux.

Thanks

John

I actually think its also really (relatively) expensive for Linux as 
well. Veritas is not in the habit doing things for the good of the 
community. Whether it worth it or not really depends on what your 
requirements are. Certainly the Veritas product provides a much 
cleaner solution in terms of including the mirroring portion within 
the vm itself (although depending on what features you want it will 
be an extra cost as well). This is better than using lvm on top of md 
(which I do at my site). 

These other products (lvm and md) are free but that also means if you 
have a problem who knows when it will be addressed. Same is true to a 
certain point with Veritas as well.

I have done quite a bit of work with VxVM on both Solaris and HP-UX as 
well as work with md/lvm. Both have their pros and cons. If you don't 
mind the cost and feel the current tools are primitive then VxVM 
might be worth it. However it you just want a reasonable 
mirroring/raid solution md/lvm might just be ok.
