Hi all, |
2 |
|
3 |
I've got a sw RAID1 that just had a failed drive replaced with an identical |
4 |
drive. |
5 |
|
6 |
However, the good drive started on sector 63 and the new drive want's to start |
7 |
on sector 2048. Fdisk won't let me create the partition table on the new |
8 |
drive as it is on the old drive. |
9 |
|
10 |
This is the good drive in the RAID: |
11 |
=============================================== |
12 |
Disk /dev/sdb: 320.1 GB, 320072933376 bytes |
13 |
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors |
14 |
Units = sectors of 1 * 512 = 512 bytes |
15 |
Sector size (logical/physical): 512 bytes / 512 bytes |
16 |
I/O size (minimum/optimal): 512 bytes / 512 bytes |
17 |
Disk identifier: 0xfc32270f |
18 |

Device Boot Start End Blocks Id System |

/dev/sdb1 63 224909 112423+ fd Linux raid autodetect |
21 |
/dev/sdb2 224910 50572619 25173855 82 Linux swap / Solaris |
22 |
/dev/sdb3 50572620 625137344 287282362+ fd Linux raid autodetect |
23 |
=============================================== |
24 |
|
25 |
However, after zero'ing out the new drive, this is what fdisk allows me to do: |
26 |
|
27 |
|
28 |
=============================================== |
29 |
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF |
30 |
disklabel |
31 |
Building a new DOS disklabel with disk identifier 0xfcd585e4. |
32 |
Changes will remain in memory only, until you decide to write them. |
33 |
After that, of course, the previous content won't be recoverable. |
34 |
|
35 |
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) |

Partition number (1-4, default 1): 1 |
43 |
First sector (2048-625142447, default 2048): |
44 |
=============================================== |
45 |
|
46 |
As you can see, I can't mirror the previous partitioning scheme and I will |
47 |
probably not have enough space on the new drive to build the RAID! |
48 |
|
49 |
What can I do? |

Take care and have fun, |
