[zfs-discuss] Diverse, Dispersed, Distributed, Unscheduled RAID volumes

2008-04-25 Thread kilamanjaro

Hallo!

[Asked by a technical managerial new person assembling a  
recommendation (sorry for my relative ignorance) and apologies for  
the long English sentence]:


Is ZFS ready today to link a set of dispersed desktop computers  
(diverse operating systems) into a distributed RAID volume that  
supports desktops being turned on and off (with a power-down, close- 
up protocol but without a schedule), and assimilates new desktops  
very easily when they come online in such a manner that It would  
distribute the network load across all desktops for both reads and  
writes?


And could, say, such a set-up email the administrator if the array is  
in danger of losing integrity (due to too many desktops being taken  
offline), with the performance proviso that the number of machines  
needed to maintain integrity should scale as more data is added to  
the volume, and the volume(s) size should grow automatically as more  
machines are added?


Many thanks

[zfs-discuss] MySQL, Lustre and ZFS

2008-02-06 Thread kilamanjaro
Hi all, Any thoughts on if and when ZFS, MySQL, and Lustre 1.8 (and  
beyond) will work together and be supported so by Sun?

Hi ZFS discuss:

I'm a daily regular reader who (usually, before this) never writes  
but finds the discussion list highly informative in furthering an  
understanding of ZFS. The discussion also provides useful knowledge  
for internal cases promoting the use of ZFS. Concerning:

 I've been observing two threads on zfs-discuss with
 the following
 Subject lines:

 Yager on ZFS
 ZFS + DB + fragments

 and have reached the rather obvious conclusion that
 the author can
 you guess? is a professional spinmeister

I'm neither pro or con any particular poster nor within the broad  
limits of courtesy do I pay too much attention to their social/manner/ 
politeness style of delivery. In this regard it seems to me (IMHO)  
that the writer Can you guess? sometimes has a sharp and personal  
edge to his comments which distracts from what he's actually saying  
(as well as raising hackles), however, at the same time, both to date  
and continuing, I and others have found/find those comments, along  
with many others, very useful in providing insights to ZFS, file  
systems, etc.

His style (lots of words) may not be to your liking but there are a  
fair number of folks who appreciate stuff being spelled out,  
especially in discussion, as this not only makes the matter under  
discussion clearer but also makes clearer the perspective, biases,  
understanding etc. of the writer (which is also important).

Being a discussion list I and other are trying to respect the time/ 
detail/research limits that many of you work with in writing the  
explanations and bringing considered responses back to the discussion  
list, so I for one am appreciative for (however they do it) those who  
find/make the time to detail and question in detail what others might  
take for granted.

Just to say that in this case Can you guess's manner may be  
unnecessarily irritating and offensive to some on this list (as it  
sometimes seems to me), but it is also true that his technical  
comments are useful for several of us, as are replies to his replies,  
and the continuing conversation. I'd much rather hear responses to  
his technical observations than his personal ones. Why not ignore the  
latter (within reason - it can't really be personal as he doesn't  
know (I assume) you or I)?

Being able to glean better understanding, performance etc. for both  
management and technical decisions when the discussions max out in  
technical directions is one reason this list is so interesting.
