I got the FXI Cotton Candy... haven't had a chance to use it yet because I'm getting a USB OTG cable on Monday... but it seems neat... flash drive sized computer =D
So Windows 8 is out and I have a new motherboard. I wish to create a RAID 1 coupling between two HDDs -- for storage purposes only (my OS is on an SSD) -- but I don't know which is the best route to take.
My motherboard (Z77 chipset) comes with the age old Intel Fake RAID, but since I only wish ...
The backup tool for Windows 8 has changed. If you want to backup just your user files, you want to use File History, which will automatically synchronize your Libraries and backup to an external location. However, File History cannot backup your whole system, including applications. File History ...
@Hennes I use RAID-0 (hardware RAID) on my gaming system, and I keep any truly irreplaceable data (besides savegames, which are too big to backup) in the cloud or on at least one other computer
but it's right, only I have the problem if it fails
Or performance increase if drives are not fast enough. (mirrors with two drives can read from two drives. This read speeds is up two twice single drive read speed
I got RAID 5 on large disks on my gaming system. and good backups.
I do not want to rebuild a large arrays with RAID 5
@JourneymanGeek I'm mainly interested in a dedi server with native performance (no virtualization), decent bandwidth but not tons, and lower cost due to low power consumption of ARM
workloads include audio streaming, HTTP(S), FTP(S), remote desktop, and compiling large software packages
@JourneymanGeek oh... as far as the advantage vs. running my own, uptime is basically it, because I firmly believe that servers belong in a datacenter, and I don't have any landline connection at home, only my LTE, which I take with me to work, so it'd be down all day while I'm at work
basically the only way to avoid the RAID 5 write hole is to have a UPS for the entire system if you use software or BIOS RAID, or a BBU for the hardware RAID controller, or RAID-Z ZFS feature
if you have none of the above, you can lose your entire array and it's no safer than RAID-0 in power failure or kernel panic
@Hennes You know, an adaptec 6405-E raid card (fairly commodity, not that high-end) has a dual core dedicated processor on-board for calculating parity bits? :P so yeah, RAID-5 is computationally expensive :-/
I installed Windows 8 pro today and accessed my Windows 7 user profile folder (C:\Users\xxx) and it showed me an access denied error with a continue button with UAC symbol over it, I hit it and it never finished loading my profile(~150gig), since it took a long time, I booted into 7 to access som...
Hetzner.de web host is great and affordable and high end hardware, but the default configuration is Software RAID-5 on Linux with three multi-TB SATA disks, and the write performance is abysmal, and the parity bit calculating daemon hogs 100% CPU
I paid them extra for a 4 port Adaptec Hardware RAID card and added an HDD and went to RAID10
@HackToHell, boot in safe mode and run cacls recursively over your entire profile and reset the ACLs clean and set full control to yourself? dunno just a guess, and it COULD screw up programs that rely on permissions being different, like, granting write access to some windows services that run as localsystem or something
or if you can boot windows 8 cleanly still, you can do the same from windows 8 instead of safe mode
you will just have to wait for the permissions to finish applying
it'll take a long time because NTFS security descriptors are pretty slow
in fact NTFS-3g, the userspace read/write NTFS filesystem driver on Linux, is arguably faster than Windows' own native NTFS because NTFS-3g ignores security DACLs entirely. lolololol
it doesn't read nor write them, everything is rwxrwxrwx
you could just manually apply the security settings in windows explorer to make sure you "add" the "Full Control" permission for your Windows 7 user account
without replacing/deleting the existing ACLs
you don't have to wipe out all the existing ACLs in order to add one
@HackToHell Just make sure nothing is encrypted. You should be able to grab ownership from either win8 or win7 and pick through the file without destroying anything
@HaydnWVN the owner security identifier can't be made to match, if the accounts were created separately at different times. you can't (easily) change the security identifier like you can change a UID on Linux. It's a unique GUID ish thing
what he needs to do is use UAC permission to forcibly take ownership of the files as the Win7 Administrator account, then grant full control of everything to the user account, then login as the user account (hoping it works without the user being Owner), then take ownership
same thing happens with a corrupted profile - windows generates a temp one, then if nothing is done and the user renames that account to their old it will appear to work, but the underlying permissions are so screwed up it's unreal
I find it poetically appropriate that Windows 8 would have such a big problem viewing a user profile from Windows 7 with both OSes concurrently installed, and require us to delve into the internals of the NTFS filesystem and NT security descriptors in order to resolve =D
proof that not only Linux requires delving into the terminal
I hate discretionary access controls anyway, they're basically smoke and mirrors if you can bypass the operating system in any way (such as uh, removing HDD from system)... I like encrypted FS for this reason :P
they are only useful at the application layer to keep ${APP1} from trampling on ${APP2} or your data
@HackToHell - What you tried to do through Windows 8, screwed up the permissions, unless you have a backup of your system there isn't much you can do. — Ramhound9 mins ago
@HackToHell Misha might have something... How important is your Win8 install? Take complete ownership in Win7, eradicate the Win8 install and start again?
@HaydnWVN I will say though I've jerked Windows around by forcibly taking ownership on a daily basis. Hasn't screwed me yet, save for the time I encrypted stuff...
I don't know what caused my Desktop (Windows XP) to blow up.
My PC freezes often. During the welcome screen, or while in Desktop or sometimes before welcome screen itself. I thought it would be some dirty activities of a virus. So, I formatted my C: partition and tried to install XP again. I'm ...
A web application / security tester needs to answer network questions in a primal way, a very low level urging originating from the subconscious, much in the same way as biological beings feel the need to procreate
I've got a problem with syncing big amount of data between two data centers. Both machines have got a gigabit connection and are not fully occupied but the fastest that I am able to get is something between 6 and 10 Mbit => not acceptable!**
