That's some new info.  I tend to follow threads, even started one ages
ago about my hard drive doing a bumpy thing for a long time after I
updated my backups.  Rich plus others informed me I unknowingly bought a
SMR drive.  I think mine has about a 15 or 20GB CMR section.  I've
noticed if my updates go to about that much or more, it gets slow. 
Either way, it does the bumpy thing for a good while after my backups
are done and I've unmounted the drive.  I just let it sit there until it
gets done.  If I don't, it just slows down faster the next time because
it starts out behind on moving the files from CMR to SMR and doing its
rewrite thing. 

My biggest point for the OP, look at its use and pick what works as
expected.  I've read, and Wol seems to confirm this, that RAID and SMR
do not go together well.  I've read some have hosed RAID thingys when
they put in a SMR drive and didn't know it. 

The biggest problem I have is when they don't let us know when a drive
is SMR.  I don't like a company that sells me something that isn't as
good without telling me.  It sort of rubs me the wrong way. 

To the OP tho, research first, then buy.  Know what you getting and that
it will work for your needs.  As I said, for the most part, my backup
drive being SMR is mostly a little annoying.  It does work.  I just
won't do it again tho.

The Seagate is a BarraCuda. Not a Barracuda. Note the slightly different 
spelling.


All new BarraCudas are SMR.

I think the WD is a Black, which is also almost certainly SMR. WD 
shafted a lot of people by shipping SMR and not telling anyone. At least 
Seagate appear to have been open about it.


And yes, raid and SMR do not go well together.

[Laurence Perkins]

With regard to SMR drives, note that there are three basic types:

Some completely hide the fact that they are SMR.  These suck, hands down.  
Performance is unpredictable and random.
Some at least advertise that they're SMR, and expose basic counters about where 
they are in their maintenance cycles.  These still suck, but at least you can 
kind of predict when they're about to get really slow.

The best ones actually advertise what the shingled ranges are, at which point a 
new enough kernel and filesystem can keep the writes to those ranges as 
sequential as possible, and you can use the big, cheap drives with very little 
performance loss.

There are a couple articles explaining how to determine what you've got and 
optimize it.  I don't have my bookmarks to hand, but it was in a discussion on 
this list a few months ago.

I agree with this because I've made this mistake, twice.  Find out the largest 
size that will fit in each slot and buy to enough of them to cover your needs.  
When you need to expand, just plug in a extra stick, or two. 

Depending on what you do, 16GBs may be enough.  I have 32GBs on mine and quite 
often during updates I hit 20GBs of memory in use.  I'm not including cache or 
anything, actually memory in use by the system.  If you need to save on cash 
and upgrade later, one could likely adjust the memory used during large updates 
by using load options etc with emerge. I don't know why but it seems I get hit 
with a Firefox, libreoffice and some other large package at the same time quite 
often.  It takes up a lot of memory doing those.  I just thought it worth a 
mention but you may have a different demand than I do.

On this, good point.  I have a SMR drive, didn't know it when I bought it, and 
I use it for a external backup that is done weekly.  Even with that, it is a 
bit annoying.  Even when it is done, it isn't really done yet.  I would not use 
this for anything where you might have a lot of large writes.  Once it hits a

I agree with this.  A badly designed power supply can really cost you if it 
goes out.  I think mine is a Thermaltake but only a few models are really good. 
 There is a thread on overclockers forum that lists power supplies by model and 
if they passed the tests they ran.  It also explains how good the protection is 
when the power supply goes bad.  I don't know how up to date that list is but 
don't skimp to much on this. I had a fan go out on one of my

I had a fan go out on one of my Thermaltakes and it ran for a bit but
blew smoke and died.  Thing is, it shut down nicely and a new power
supply got me running again.  You want one that has good protections in
place otherwise, you could be building a new rig. 

Hope that helps.

What's the largest chip a slot takes? If you can afford it, buy two of 
those. My new mobo takes 16GB, and they were only GB£50 each - £100. If 
you ever want to upgrade the ram, you won't need to "chuck and replace".

gtkd probably doesn't support that version of dmd just yet.  Just a

This appears to be working... will report back when its "done".
(Although I wonder why dmd-2_096 wasn't in the list ?)

Sorry, for this, I copied my *own* use flag file with the package for
which I specify a dmd version, instead of yours.

The point is still the same though, packages that require dmd have to
be specified which version of the compiler to use.

You have to manually specify, via a USE flag, which version of dmd that
you want.

eg. "net-misc/onedrive dmd-2_095" in /etc/portage/package.use/dmd

It is a bit bothersome to have to manually update this when dmd
updates, but that's just the way it is packaged, I suppose.

This tells you that dev-libs/gtkd needs at least one of (any-of) the
listed USE flags. You can enable USE flags in
/etc/portage/package.use¹. For example, to enable gdc-11_2_0:

echo 'dev-libs/gtkd gdc-11_2_0' >> /etc/portage/package.use/dlang

 Any Dlang users/experts out there?

The following is hanging me up:

 # emerge --ask --verbose --update --deep --newuse --changed-use

>>> Syncing repository 'dlang' into '/var/lib/layman/dlang'...

Action: sync for repo: dlang, returned code = 0


 # emerge --ask --verbose --update --deep --newuse --changed-use

These are the packages that would be merged, in order:
