"Everything was fine" mean; I created partition and then formatted it |
| 13 |
without any errors or warnings. There are messages from syslog: |
| 14 |
----------------------------------------------------------------------- |
| 15 |
Jan 22 23:43:16 localhost EXT3 FS on sdb1, internal journal |
| 16 |
Jan 22 23:43:16 localhost EXT3-fs: mounted filesystem with ordered data |
| 17 |
mode. |
| 18 |
----------------------------------------------------------------------- |
| 19 |
Then I copied my data to this new partition. I could access this data |
| 20 |
from new partition without any problems. Next day: |
| 21 |
----------------------------------------------------------------------- |
| 22 |
Jan 23 10:23:46 localhost VFS: Can't find ext3 filesystem on dev sdb1. |

Why it can happen when replacing two partitions with large one? |
| 32 |
|
| 33 |
I tried gpart with this output: |
| 34 |
----------------------------------------------------------------------- |
| 35 |
#gpart /dev/sdb |
| 36 |
Begin scan... |
| 37 |
Possible partition(Windows NT/W2K FS), size(40959mb), offset(0mb) |
| 38 |
Possible partition(Linux ext2), size(197512mb), offset(40959mb) |
| 39 |
End scan. |
| 40 |
|
| 41 |
Checking partitions... |
| 42 |
Partition(OS/2 HPFS, NTFS, QNX or Advanced UNIX): primary |
| 43 |
Partition(Linux ext2 filesystem): primary |
| 44 |
Ok. |
| 45 |
|
| 46 |
Guessed primary partition table: |
| 47 |
Primary partition(1) |
| 48 |
type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) |
| 49 |
size: 40959mb #s(83885696) s(63-83885758) |
| 50 |
chs: (0/1/1)-(1023/239/63)d (0/1/1)-(5547/239/62)r |
| 51 |
|
| 52 |
Primary partition(2) |
| 53 |
type: 131(0x83)(Linux ext2 filesystem) |
| 54 |
size: 197512mb #s(404505360) s(83885760-488391119) |
| 55 |
chs: (1023/239/63)-(1023/239/63)d (5548/0/1)-(32300/239/63)r |
| 56 |
|
| 57 |
Primary partition(3) |
| 58 |
type: 000(0x00)(unused) |
| 59 |
size: 0mb #s(0) s(0-0) |
| 60 |
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r |
| 61 |
|
| 62 |
Primary partition(4) |
| 63 |
type: 000(0x00)(unused) |
| 64 |
size: 0mb #s(0) s(0-0) |
| 65 |
chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r |
| 66 |
----------------------------------------------------------------------- |
| 67 |
I also tried it with data about cylinders, sectors and heads taken from 'fdisk -l /dev/sdb'. |
| 68 |
It produces same output. But I created ext3 on whole disk, I'm sure. |
