linux raid5 problem
Posted: Sun Mar 11, 2012 10:24 pm
Hi,
I had a raid5 in mandriva 2010.2: 5x1TB
It worked very well until the MB is failure. Change the MB, I installed again MDV2020.2 after installed and all updates, I connected the 5HD of the raid. I rebooted the computer and all good. I mounted the raid to copy some configuration files, copied them and rebooted the computer. Upon restart, I noticed with surprise that the raid was rebuilt. Let him finish, no way. When he finished and I wanted to mount the raid, came the message: no partition table. @ # @ $ ^%
Reviewing the configuration and log, I found that initially the system had recognized the HDs as part of a raid in this order: cbdef. After restarting were: bcdef. @ # $% Do not know why.
At this point, I stopped him again raid and assembled with the HD in the original order. When finished rebuild mdadm I tried to mount the raid and left the message: no format the partition.
In another computer I have installed virtualbox. In a Linux, I have recreated the raid5, I have generated several files of different sizes and then I generated the same disc replacement happened to me on the computer. I've even created a complete mess of the discs, not just 2. Always, when returning to the original setting, my files are listed and the correct cheksun. (created with md5sum)
After this: google -> r-studio
I assembled the raid in different forms, scanned, reviewed, etc..
Apparently, the raid had created it with a chunk = 64k. When I came back to arm did not put this value, so he put the mdadm default = 512k.
I assume that this was a mistake but I'm not sure. Anyway, my intention is to recover my files.
I need help with:
1) Which version is better: The windows or linux? I will use locally.
2 When I bought the license, I can use it in win and lin? or different license?
3) In the scan, r-studio has found several files. These are listed in different colors. What does it mean? There are green, orange, red.
4) has found most of the files, but some of these are within the inode item with a red cross, I mean I can not recover?
5 I have found a tutorial on how to detect the order of the disks. The problem is that is ntfs. Anyone know how to do ext4?
and also how to find the original values?
Thanks for the help you can give me
