A while ago when I was still on Windows I had two secondary 1 TB hard drives that used a raid0 setup, fakeraid I believe with Intel. My primary hard drive died which seemed to have messed up the raid as well.
Using dmraid I get the error: "isw: wrong number of devices in RAID set" when trying to use most commands. When trying to rebuild, "Rebuild: raid0 cannot be rebuild".
Info when using
ERROR: isw: wrong number of devices in RAID set "isw_bcibgbaaec_Comp" [1/2] on /dev/sdc *** Group superset isw_bcibgbaaec --> Subset name : isw_bcibgbaaec_Comp size : 1953519872 stride : 256 type : stripe status : broken subsets: 0 devs : 1 spares : 0
The info for
fdisk -l on these two drives:
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x6e697373 Disk /dev/sdd: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000
I can see that the disk identifier of the 2nd drive is showing 0x00000000, which I assume it an issue. No files also under /dev/mapper aside from control.
Other things to mention when using disk utility, the first drive shows "Unknown Scheme" under partioning while the second drive shows "Not Partitioned". The unknown scheme drive still shows many data blocks with labels "Free 112 GB", "871 GB RAID Component", "372 GB RAID", "Free 257 GB", "Free 18446743 TB". Have no idea why it shows so many free space labels as well as 18446743 terabytes? Wow. The not partitioned drive just says "1.0 TB RAID Component".
Does anyone happen to know what could be wrong? Am I able to fix the broken raid? When I boot up the PC it actually says "normal" for the raid status so I was hoping it could be fixed.
If you have any suggestions for what I should try or if you need any additional information, please let me know.
