I have made 2 passes at installing wheezy, both massive failures.
The first problem is that you cannot bypass the disk partitioner and it 
does not understand about the new 4k per sector disks, so it screws up the 
partitioning.  Linux CAN handle that, but disk speed takes a 50 or more % 
hit in read, and up to a 90% hit in write speeds.

This is not a problem on the machine computers as both of those have older 
250Gb drives that are 512 byte sector drives.

GParted can move the partition boundaries around and has successfully 
fixed a manjaro (arch based) install I have done on this same drive, but 
it destroyed the second wheezy install trying to fix that.

Now that I know I can fix what the wheezy partitioner does, I will 
probably give that another shot.

I raised several sorts of hell on the debian list about that, and to a 
man, they said I COULD bypass the partitioner, but damned if I could do 
it.  Maybe a 3rd time is a charm?

What has been everyone else's experience with this?

I need to do something relatively quick, my main drive hiccuped and was 
read only when I woke up this morning. a reboot with a lengthy session of 
fixit y's issued to e2fsck seems to have fixed it, but for how long?

What I think is happening is yet another session of crap sata cables. You 
cannot buy a sata cable that doesn't have the hot red colored plastic. and 
that crap is a 3 year time bomb, something in THAT red die eats the copper 
up, and I have been pouring the copper out of the end of it as a fine red 
dust where there used to be a conductive wire ever since the CB Radio 
makers found the J.A.Pan mic cables were cheaper, in about 1970.  And I 
still have 2 of them in this system. I also have 3 of the red ones that 
have failed hanging on a drawer knob behind me.  Reminders to never ever 
buy the red ones.

There will be a couple of minor config changes when going from 2.6 to 2.7:

http://linuxcnc.org/docs/2.7/html/getting-started/index.html#_updating_your_config


I think both 2.6 and 2.7 are reasonable candidates for a new machine
build today.  2.6 has more runtime out in the community, so any bugs
that are still lurking are presumably minor.  But 2.7 has the new
trajectory planner, which performs better and we'd love to get more
runtime on it and get bug reports if you notice any problems.

So it's really up to you which you prefer.

I don't think that there will be any config changes to upgrade from
2.6.N to 2.7 (unless someone knows better) so I would suggest starting
with 2.6 rather than waiting.

[Emc-users] SWAG on the release date of 2.7

2015-02-02 Thread Greg Bentzinger 
About to start a new retrofit conversion in the next few weeks and would rather 
put off the software side until v2.7 is released than have to convert from 2.6.

If it is beyond the near horizon am I good to go with v2.7 pre?

A decade ago I was a heavy Gentoo user (lets build every little part custom to 
run the best on our existing hardware setup)

But for the last five years I have been getting paid to help admin a windows 
cluster and that means alot of mind numbing user hand holding and its wore me 
down over time.

Sometimes I stare blankly at a terminal window trying to remember the proper 
command syntax needed. I blame M$, and deny that age or other factors could be 
causing me to turn into a Zombie.
