 Posted: Sat Oct 16, 2004 7:15 pm Post subject: ext3 filesystem borked? |
 |
|
Recently I couldn't mount my /home partition.
| Code: | | mount: wrong fs type, bad option, bad superblock on /dev/hda4, or too many mounted file systems |
I did e2fsck:
| Code: | amsterdam root # e2fsck /dev/hda4
e2fsck 1.35 (28-Feb-2004)
Group descriptors look bad... trying backup blocks...
Inode table for group 892 is not in group. (block 18583)
WARNING: SEVERE DATA LOSS POSSIBLE.
Relocate<y>?
|
If I choose yes, e2fsck makes pass1, and restarts it once and again, never stops. The error isn't fixed. If I choose no, e2fsck starts scanning the filesystem until last pass, when I get:
| Code: |
SNIP...
Free blocks count wrong for group #6 (0, counted=32254).
Fix<y>? yes
Free blocks count wrong for group #7 (0, counted=32246).
Fix<y>? yes
Free blocks count wrong for group #8 (0, counted=32254).
Fix<y>? yes
Free blocks count wrong for group #9 (0, counted=15949).
Fix<y>?
SNIP...
|
No matter what I answer, in later runs I get exactly the same errors and the filesystem remains unmountable.
Is there anything I can do, if not to save the filesystem, to save any file inside it?

| You did not have yournaling enabled? There are some recovery tools like e2retrieve. Give it a try. |

I'm trying e2salvage, but it is sloooooooooow. What about e2retrieve?
Edit:
Also slow, README says.

| If it was fast, it woudl be a feature in the filesystem itself. The closest you can get is journaling, but that's not quite the same thing. |

I extracted almost everything from my disk, half of it mantaining directory structure, half of it bound to lost+found.
The program I used is e2extract, tricky to set up, but very, very effective.

I am trying to use this toolset and am finding it "tricky" as well. (And hoping to find it very, very effective as well)
Specifically, just trying to get past the first step, I ran stat_inodes against the raw device and each line reports:
| Code: | | <NODE> - n - 0 bytes, 1 related, age , links - ASCII text |
Did you configure anything in that file beyond the following?
| Code: | | $device = "/dev/<device>"; |
Thanks for your help.
