So, I was just thinking, what if I had two 80 GB HD's and a 160 GB HD? I could then gstripe the 80 GB's, and then on top of that stripe those with the 160 GB. Then I'd have around 320 GB or so, I could then gstripe that with a 320 GB HD.
Ohhh the possibilities. By that time, I'd probably just use some sort of gvinum, since apparently it can do raid 5 over hard drives that are not the same size. Something i'd like to eventually do as a way to keep my data safe and a secure.
I was really bored. Which normally results in some destructive thing happening to something I am playing with. This time it was Some of the hard drives in my FreeBSD box. Just a little back-story:
/dev/ad0 - 20 GB /dev/ad1 - 40 GB /dev/ad2 - 100 GB /dev/ad3 - 60 GB /dev/da0 - 8 GB /dev/da1 - 8 GB
So, I had already made a gstripe(8) out of the two SCSI drives, da[1|2], however I wanted to see if I could do the same with ad[1|2|3]. As I did not want to resort to gvinum, which is rather heavy, and I was unable to figure out how it worked. The entire point behind gstripe is that since it is striped, the writes/reads are faster since it writes/reads to all the drives at the same time. So first I tried:
gstripe label -v st1 /dev/ad1 /dev/ad2 /dev/ad3
That however complained that it would only use 40 GB's on all of the drives, since the smallest drive in the collection was 40 GB. I then read up on gconcat(8), which concatenates all the drives together to look like one big drive, without the speed improvement of striping. So I figured, since FreeBSD's gstripe is GEOM based, it should not care about what the underlying data sink is, just that it is a device, so just maybe this could work:
gconcat label -v gb100 /dev/ad1 /dev/ad3
So now I had created a 100 GB "hd" at /dev/concat/gb100. I now did what I was planning to do:
gstripe label -v st1 /dev/ad2 /dev/concat/gb100
No problem! :-D. I now had 180.48 GB, of which only about 166 GB was usable. Which is still excellent. As it still came with a speed improvement. Followed up with the standard advice from the handbook I did the following:
bsdlabel -wB /dev/stripe/st1 newfs -U /dev/stripe/st1a mount /dev/stripe/st1a /mnt
Which got me the following:
/dev/stripe/st1a 180G 5.5G 161G 3% /mnt
Full:
Filesystem Size Used Avail Capacity Mounted on /dev/ad0s1a 496M 63M 393M 14% / devfs 1.0K 1.0K 0B 100% /dev /dev/ad0s1e 496M 230K 456M 0% /tmp /dev/ad0s1f 15G 2.2G 11G 17% /usr /dev/ad0s1d 1.4G 115M 1.2G 9% /var /dev/stripe/st0a 16G 4.0K 15G 0% /usr/scsi /dev/stripe/st1a 180G 5.5G 161G 3% /mnt
w00tage. Next up I might actually add gdbe(8) or geli(8) even in front of the stripe, so that I will have an encrypted stripe. Talk about stacking. Might give gvinum a try sometime :P
All working:
keyhole# gconcat status Name Status Components concat/gb100 UP ad1 ad3 keyhole# gstripe status Name Status Components stripe/st0 UP da0 da1 stripe/st1 UP ad2 concat/gb100
I am moving my domains away from registerfly.com (not linked on purpose) and am moving them to GoDaddy. I was sick and tired of RegisterFly's website loading slower than molasses coming down from a mountain top. The inability to keep my account secure (someone logged into it, I got an email, and immediately change the password).
I apologize if there are any domain hickups in the process. I hope this helps me in the future for when I need to work with my domains, and change the DNS settings. Waiting for the login to happen for over 40 seconds is just not acceptable.
Wanna play with a christmas tree remotely? Turn it on and off in our lobby? Here is your chance, visit http://uatree.0x58.com/index.html to turn the tree on, off, or scroll the lights up and down. And maybe, if the camera is pointing right, you can catch a glimpse of it on there!
Thanksgiving was great, I went over to a friends house and he cooked us an awesome dinner.
The food was great. I have never had soo much turkey in a day. I must say though that it was awesome being there with everyone.
We were all in and out of conscinceness after around 8. Then at 2 in the morning we all got up to head out to the local Best Buy to go stand in line. At first it was to get the Xbox 360's that they were supposedly selling for $100, but we learned while waiting in line that that was all a hoax. The real reason I came then, was to get myself a nice 22" Westinghouse widescreen LCD screen for $200. This thing has more inputs than a whore. It can do 1080i, and thus has Composite inputs, DVI input, VGA input, and standard video input, and S-Video input. It also has two 2.5 W speakers built in. It does 1680 x 1050 Widescreen over DVI, which is an awesome resolution. It is VERY awesome to use for watching movies, and is absolutely handy when it comes to needing screen space to do programming, since I can now use my laptop screen as a backup and leave Safari open on that with notes or other information.
Widescreen for the win!
