3ware 9500 and large drive issues

2006-03-31 Thread Vincent Meanie
I am attempting to use a 3ware 9500s, the problem is how it displays  
the 8 disks as one large 2.3tb disk.
There are documented issues with disks over 1tb, will partitioning  
under this limit prevent further issues, or will I have to look  
forward to errors in the future from the filesystem?


Granted 3.9 will be out soon, but I am just going off of the  
information I have at hand. I attempted to use an unsupported card  
that could present sized luns to the OS, but it was an unreliable  
production sample, and the 3ware card is what I have.

says it pretty clear, I hope.  One large 2.3 TB disk is unlikely to work.

3.9 won't change this.  4.0 probably won't.
Work is being done, but slowly and carefully, just as I'm sure you would 
want something so critical to be done.  No one wants to lose data on 
their 256M flash device because of a sloppy addition of multi-T support.


There are some kinds of work that are just plain terrifying to do, file 
systems are way up there, if not top of the list.

...speaking of unreliable...
3ware isn't anyone's favorite around here...
