replace the drive of an old type apple time capsule with an ssd

just the other week I tried to find out if the old square apple time capsule could run with an ssd drive. you know, the noisy hot one with an internal 3.5" sata drive between 500gb and 3tb? short answer: yes, you can.

why would anyone want to do that? ssd drives are super expensive!? simple answer: because I could ... nah ... of course I had my reasons.

I moved my time machines backups to the synology ages ago and was left with two different versions of the square time capsule. recently I became more and more annoyed with my wifi situation and thought - hey - those time capsules ... if they didn't have those burning hot noisy sata drives in them they should do well as low power wifi bridges with air print capabilities. if only they could run with an ssd ...

so after some research on the net I found nothing, nil, zilch - not a word on if I could replace the internal drive with a small ssd drive. so I ordered two super cheap 32gb king diam s100 drives from amazon for just more than eur 40. I could have gone with 8gb drives for eur 32 total but if those hadn't worked for this project I would have had to pay for the return shipping cost. yeah, german laws and all that ... who cares.

so yes, the drives work in the old type time capsule and yes, I could use roughly 30gb of space there which I won't. the smaller drives most probably would have worked, too. I would expect the smallest thing with a sata connector to work actually.

and by that I was able to re-furbish two perfectly good wifi access points for just eur 40 instead of purchasing new airport express or airport extreme base stations between eur 100 and 200.

oh no! not monowall! it's dead, jm.

just last week I learned Manuel Kasper decided to put m0n0wall down after 12 years of excellence. I've been using the monorail for almost as long when I first got a soekris embedded pc for it and I think it is still the best choice for those tiny machines.

now I need something new.

any hints on what webgui firewall to put onto my soekris net4801. I was considering just OpenWRT with some firewall builder but I'd prefer something more klicki-bunti if possible.

unless any good hints come up I'll probably just go down to the bare metal like in the old days. owning several rack-mounted wrap pcs and soekris net4801 machines I don't want to get any new hardware, to be honest.

update on the new mac mini

like I expected the mac mini is fast. took it about a month to be shipped - apparently due to a shortage in fusion drives reportedly put into iMacs on priority but since I set it up on my desk last Saturday it has been quick like Han Solo.

the only thing missing at the moment is Thunderbolt as I lost the port to my secondary display. any solution to use both, two displays as well as the Thunderbolt port, would be helpful.

the specs are pretty much bottom right - everything maxed out - I didn't even stop at apple care. this machine shall help me with my personal projects for the next two to three years. what amazes me most is how this tiny thing is running circles around its older brother, my Mac pro eight core 2.8 XEON system. about the same amount of ram, about the same processor but much newer and only four cores - a smaller graphics chip … still the machine is faster and feels much more responsive.

… and it is quiet.

synology accepted

went for the Synology disk station ds413j the other day. a little NAS now stuffed with four Western Digital Red drives. It didn't play well with my DLink green switch at first but since I replaced the switch it goes and goes and goes. it stores data as fast as I can shovel it from my drives.

I accept the Synology as apology for the shit Drobo I'm still suffering from. Since the Drobo has now become obsolete I used one of its less well known features and reduced its total capacity drive by drive - its now a three terabyte raid and I'm considering to use it as backup storage behind one of my time-capsules. don't know if that can work but will sure find out.

all that is part of the preparations for the maxed out Mac Mini I've been waiting for for the past two weeks now.

considered an imac but went for the mini

my mac pro is getting old. the gforce graphics accelerator died and I had to go back to the ati radeon the machine had beem shipped with originally. even four gigs of ram decided to just disappear but maybe I can get them back - who knows. anyway - this machine has almost five years on its back and with its many fans and the eight xeon cores it consumes an unreasonable amount of energy compared to modern cpus. in short - a new computer had to be bought.

I waited for the new imac to come out before I finally came to my conclusion. I went for the mac mini. yes, the imac does have more horse-power and a much nicer display. but I already own trackpad and keyboard, plenty of storage, acessories, usb hubs, two 24" displays and whatnot … and the mac mini is much faster than my mac pro - plus it packs more ram. together with the fusion drive and probably a lacie raid it will be on the same level if not slightly above the mac pro and it will consume less power performing the same tasks faster.

what else is wrong about the imac? I'm still not comfortable with the idea of replacing the computer together with any of its failed components. I like the idea to keep things separate. what makes a macbook or an ipad strong just doesn't feel right with a desktop. I considered a powerful macbook as well but there is no real docking option for the macbook and I'm not comfortable running the notebook with the lid closed because of heat building up under the display.

it's going to be a mac mini - I already ordered it. didn't go for the server because there is no fusion drive for it and the drive option is a bit slow. with any luck it should arrive next week and if it's any good I'm gonna post about it here.

philips hue: want!

about two months from now I'm going to buy the most expensive light bulbs I ever owned - except from projector bulbs and photography flashes maybe. it's overdue and I really do want philips hue!

if in doubt ... use xen

it's done, I've decided and it's become a xen system on lenny. to sum it up real quick: ubuntu server: pain in the arse. kvm very much unfinished busines. vmbuilder hyped crap. virsh pretty much is like masochism.

if I hadn't spent all my energy on trying to get virsh and kvm running on ubuntu first and later on debian lenny - well - I might have given centos a try. but after two-and-a-half day I was just too exhausted for further experimenting and just worked with what I knew would work: debian lenny, xen and lvm. xm-create-image works like a charm and does what it promises. not half of it or only two thirds right and the rest is a mess - it just does what it can and that it does very well.

in fact I already started migrating services to the new box. the weblog is already there. I couldn't be happier. the really big thing is going to be the zimbra migration but I've done that before and it worked every time. so no bad expectations here.

I've decided to drop ejabberd since I'm the only user it's kind of an overkill. also I guess zimbra's jabber services should have improved by now - so I'm gonna try that.

I haven't yet decided if I'm going to upgrade the old server or use the old machine as backup system. will figure that out sooner or later - got enough time for thinking, now that the new system is running well and migration seems to be going on pretty easy, too.

firt blogpost on the new machine - hope it works - fingers crossed ;)

data rescue saved the day

when I came back from london last month I noticed my mac behaving a little different from how I remembered it to. it wouldn't open disk images, it seemed to have stopped serving torrents although the internet connection was working and it wouldn't open files or applications. soon enough just about two hours later it just died on me. after a not so quick reboot I noticed the drobo wasn't coming up. I tried to check it with the disk utility but it wouldn't mount and the disk utility blabbered something about a directory being something with something blah foobar. I had been pondering to buy disk warrior on several occasions so I just went ahead and got me a copy. for $99 it turned out to be able to make the drobo accessible again but it wouldn't repair it because of some rather undefined problems that also made the scanning take ages - well today I think disk warrior is priced far to high for what it does.

next I had to buy some large usb-drives to recover as much data as I could. it took me over a week to suck all the data from the drobo and after some more crashes, reboots and several severe nightmares later my recovery work was done and I had all my encrypted sparsebundles back - just one wouldn't mount. the one that wouldn't mount had a virtual size of 4 tb and a real size of 550 gb and as it turned out it wouldn't mount because just about ten band-files worth 256 mb were missing from the band directory in the sparsebundle package.

this has happened before and would happen again - but not to me it hadn't.

after some googling around and reading this and that knowledge base discussion I was ready to give up. apples mount process just wouldn't accept a broken sparsebundle with missing band-files - it didn't matter if those were even used or necessary - it just wouldn't mount it - basta.

then I googled a little more, finding the article "repairing corrupt / damaged sparsebundle" pointing to this article "repair / rebuild damaged .sparsebundle" which finally gave me the solution: data rescue 2 which had been updated to version 3 by the time and which proved to be the helpful companion I needed to get my files back. it crashed, too but after just two more days it had recovered all the files I needed from the broken sparsebundle into a new one. the final clue suggested to mount the broken sparsebundle using the -shadow-option of the hdiutil. this then presented a readable and writable block-device for prosoft's data rescue (link removed on prosoft's request) to work with in expert mode.

although the 3d interface of the tool is a little childish and very much unnecessary the tool works great and is great value for the $99 I had to pay for it. it can't do wonders but for what it's worth it recovered all the data I needed and that's worth a lot to me.

a few final words about the sparsebundle file format: it sucks! apple should have the responsable team whipped until they get their heads out their asses and fix it.

- it's so fault intolerant it feels like it's from the eighties - all the journaling in the world can't help a sparsebundle if it's lacking band-files or if band-files and plist-file mismatch - dudes, get it fixed!

- there is no hashed directory-structure for the bands there are just millions of band-files sitting flat in the band directory waiting for accidents to happen

- there is virtually no usable documentation anywhere to be found on this sparsebundle packaging format - how open is that?

Faulbaer (and why does mac os x go insane beyond ten or more attached sparsebundles?)
