Rebuild Raid 1 Without Losing Data
E.g. 1 XOR 0 XOR 1 XOR 1 XOR 0 = 1. Luckily it is a backup and not a production server.

It did install but it couldn't connect to any of the drives. Here is something to consider if you are using a PC Dell Perc card this is the ideal time to switch it out with a higher ram capacity Adaptec E-PCI or Hooray for rules! To recover let's say this bit on disk C, then it would be A XOR B XOR D XOR E XOR F = C, thus 1 XOR 0 XOR 1 XOR
Rebuild Raid 1 Without Losing Data
Most raid controllers, when a disk fails, you just replace the disk and the array should rebuild automatically, particularly if you are using raid 1. In a RAID1 system, the same data is written to BOTH disk units, but not at exactly the same time - just really close together.

One failed hard drive out of six is just not efficient sir.Start your server rebuild by replacing the failed hard drives, setting two raids one raid 1 for the operating system So kind of 2 issues, i haven't given up on the second and will tackle it when i get home but could definitely use some pointers as i've been working on Yes No Is it easy to find? On installing a drive to rebuild, s100/110/300 usually make own array, but no drive in it in OMSA and controller bios : delete dummy array. Try rebuild/make hotspare of that drive.
The question is for you, Alex: which one of these things is incorrect? 1 prev 1 2 next This discussion has been inactive for over a year. Vista Ultimate x64 SP2, used Vista disk (no service packs) to attempt a repair which i believe has screwed up my system files/drivers back to the original vista files. Boot back into the recovery disc and I can access the test files on the array again. Migelo, Dec 30, 2011 #9 Sean Guest More disks means more processing for writing data, so write operations potentially slows down with more disks in the array.

Bizarrely, the Windows 7 recovery disc can create a RAID5 array, which I've successfully tried with 3 hard disks and could copy files to. https://forums.geforce.com/default/topic/356349/nvraid-how-to-rebuild-degraded-arrays/ But the main thing is, that it allows you to extend the array very easily. Rebuild Raid 1 Without Losing Data Its first step would have been to determine which disk had all-good data. Intel Rapid Storage Technology Windows 10 Dell said same thing and needed reassurance from the field. 0 Chipotle OP Svarog Apr 30, 2014 at 3:09 UTC Scott Alan Miller wrote: If you do lose
Thanks. Currently rebuilding RAID-1 Primary Drive and Secondary RAID-1 has been established. Just the other evening I was reading about Windows' new feature called "Storage spaces" that will be introduced in windows 8 (already available in windows "Developer preview").

I'm still having OS issues, this has been the biggest problem i've been facing but i almost have this worked out (or maybe not). Sean, Dec 30, 2011 #10 Migelo Guest So I was correct, number of XOR operations = number of disks - 2 Thank you for the deep explanation of RAID5!
They had the same thing, 24 disks in RAID6 and he pulled one out and showed to everybody while it was still hot . The other method is to force a rebuild through a raid managment utility if one exists for your server implementation. Can you take an image to a usb drive with something like driveimage xml? 0 Anaheim OP Helpful Post AnotherITMan Apr 30, 2014 at 3:16 UTC Make sure http://bornsunsoft.com/solved-raid/solved-raid-0-uh-o.html LVL 1 Overall: Level 1 Message Author Comment by:Tom_Hickerson ID: 203972722007-12-03 Yes sorry all it is a raid 1 mirror.
Sometimes drives are marked as degraded but not completely faulty and you can still get data from the array. 2 failed drives in a RAID5 is the time when you start
