8 OK, I've randomly mounted partitions, and now I'm stuck because I don't
9 know what the original /etc/raidtab was. /proc/mdstat just says:
10
11 Personalities : [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
12 unused devices: <none>
13
14 which looks like nothing is used in any RAID set. Autodetect seems not
15 to be working, perhaps because the ID wasn't set to 0xFD or 253. Each
16 drive has identical partitions:
17 Device Boot Start End Blocks Id System
18 /dev/hda1 * 1 2 16041+ 83 Linux
19 /dev/hda2 3 70 546210 83 Linux
20 /dev/hda3 71 138 546210 5 Extended
21 /dev/hda4 139 9682 76656636 83 Linux
22 /dev/hda5 71 104 273104+ 83 Linux
23 /dev/hda6 105 138 273104+ 83 Linux
24
25 and /dev/hd[aceg]1 is "/boot" on each one.
26
27 all the other /dev/hd[aceg][2-6] mount says:
28 mount: unknown filesystem type 'linux_raid_member
29 obviously this is the raid. But how do I get to it?
30
31 All "/boot"s mount ok and are readable with some kernel files and stuff,
32 however /dev/hdc1 give some errors:
33
34 hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
35 hdc: dma_intr: error=0x40 { UncorrectableError }, LBAsect=585, sector=575
36 hdc: possibly failed opcode: 0x25
37 end_request: I/O error, dev hdc, sector 575
38 __ratelimit: 22 callbacks suppressed
39 Buffer I/O error on device hdc1, logical block 528
40 Buffer I/O error on device hdc1, logical block 529
41 Buffer I/O error on device hdc1, logical block 530
42 Buffer I/O error on device hdc1, logical block 531
43 Buffer I/O error on device hdc1, logical block 532
44 Buffer I/O error on device hdc1, logical block 533
45 Buffer I/O error on device hdc1, logical block 534
46 Buffer I/O error on device hdc1, logical block 535
47 Buffer I/O error on device hdc1, logical block 536
48 Buffer I/O error on device hdc1, logical block 537
49
50 so it looks like there's some problems with hdc. Are there any disk
51 hardware testing tools on the gentoo minimal live cd?
52
53 thanks,

57 It's simply unbelievable how much energy and creativity people have
58 invested into creating contradictory, bogus and stupid licenses...
