Hi to all,

Anyone work this NAS and know the default of the strip size and the parity (right).

Thanks

when using the UFS i can mont the raid with soft raid.

choose the explore i can see some folders the other is missing

in the NAS box i can see that the
- free space is 2TB
- Used space 2TB

it looks like dont have files there, this happen when the disk from the NAS failure and them the client change the disk and rebuild the array.

When i make a scan of this it give error about at 1hour of scanning , send the report to the (sysdev labs), but no response at this time about that error.

so i made an image with this settings in a 2TB file.

them try to scan the file with RAISE XFS, but the resuls where not good all the files are corrupted.

Anyone have other idyea ?

Thanks in advanced

Zebong, MSN tonight. I have an idea... a bright one

Hi again,

I could find the right values for this NAS so i put 4 new disks and creat the array raid 5.
Copy some pictures to the new array, remove the disks from the NAS, and rebuild it with UFS and i cold get 100% of the files where ok.

So back to my 4 disks ( 3 + 1 BAD Disk) clone the bad disk, and mount again with UFS.
Made an image of 2TB, them scan the image but i have this in pictures.

i have this exact raid system i working on now -- any hints as to the stripe size or parity, etc would be very helpful, i'm having a tough time finding them. i don't have the original unit to re-build a new one and examine the parameters so any help or hints would be helpful. so far i've been trying raid reconstructor, r-studio, and x-ways.
thanks!!

Neither of these softwares support XFS, which is the filesystem used by the unit.

thanks for that hddguy!! i've switched to UFS explorer with raid reconstructor now, getting somewhere, but not sure if i quite got everything right just yet. looks like 8kb stripe which starts at 8,225,281 sectors - as the first sectors are identical on all four drives (some kind of recovery partition). i was told this was a raid5 (but not sure) and also don't know the parity rotation (if it is raid5). any more help or clues if you know would be very appreciated.
thanks!

just got it!! thanks so much for your help - it was key! i had to use UFS explorer, that was the only program i had to read xfs. i think the final working settings were (not sure because it's copying now and i'm not gonna stop it at this point): 4kb stripe, raid5, starting at the second partition, backwards dynamic... will report back on these settings when this finishes for future reference.
thanks!
