 Posted: Mon Jan 20, 2003 9:18 am Post subject: harddrive woes |
 |
|
I moved some harddrives From Gentoo box A to gentoo box B. let me draw a diagram:
| Code: | --------- ---------
| Box A | -> harddrives -> | Box B |
--------- ---------
|
See? not all too difficult. I turn box B back on and mounted the drives. two of the harddrives are perfectly fine. the other two only show the lost&found directories and none of the data. Which isn't a good thing, all the important data were on those two drives. 
Each harddrive I moved is ide and they are all using ext3. anyone have any ideas what happened to it and how i can possibly get my data back? |

| Out of curiosity, what happens if you move the drives back? |

note: Filesystem features: has_journal dir_index filetype needs_recovery sparse_super on both of the drives. Not that this isn't blatently obvious, it's a start. any idea on how to "recover"? |

Here a thought: If you didn´t move all the drives, or the root file system of the original system isn´t on the new system, the journal may not be found. I think that ext3 can store the journal for partitions on either the partition or the root filesystem. That might explain your dumpe2fs results.
Try mounting the disk as ext2 instead of ext3. If that works, I think you can then re-generate the journal by doing the ext2 to ext3 conversion.
Good luck. |
