30GB partition only allowing <1GB ?

[tinypoodle]

It is possible to create a fs much smaller than the underlaying partition - rest of disk partition space will be unusable.

2 pages, and the output of df -h has yet to be posted.

[mb0]

nor requested. I guess you want that with sda2 mounted? ..and, the whole lot??

e:

Code: [Select]

Not requested?
You complain about the output of df but don't think to post it?

[tinypoodle]

If I were you, I'd copy files from sda2 to sda1 and then just format sda2 from scratch - preferably after first fixing the partition table.

[mb0]

> preferably after first fixing the partition table

what /how?

for reference, not a problem to wipe sda2 (unlike sda1)

[tinypoodle]

"testdisk" is a good tool to fix partition tables.

[gerald_clark]

If sda2 is an ext filesystem, why not run resize2fs?

[tinypoodle]

If sda2 is an ext filesystem, why not run resize2fs?

I had been considering suggesting that, but given all the [missing] evidence would consider it more reliable to format from scratch.

[curaga]

resize2fs can't change inode count IIRC, which may be a problem.

[mb0]

so i went through the testdisk procedure, required a restart so i did and now..

Code: [Select]

Syslinux 4.01
Error: no configuration file found
no default or UI configuration directive found!
boot:


[mb0]

soo.. is there anything i can enter at the boot prompt?

The deafening silence makes me think i'm probably screwed?

[Rich]

Hi mb0
The error message makes it sound like just the config file for the bootloader is missing, though I suspect it may
be worse than that. My recommendation is that you boot the machine using a CD or a USB thumb drive. Then
mount sda1 and sda2, and check what is left of the directory structure.

[curaga]

Yes, you likely just need to reinstall the bootloader from a live cd.

Well, that was weird..
my former /dev/sda2 became /dev/sda1  ..not so crazy..

/dev/sda2 however, was a partition that i had deleted *before* i repartitioned (ie before i ever started this post). And former-/dev/sda1 (you know, the one with all the useful stuff on) was nowhere.

So i started again. FFS...

so, that over with, what can i do before i invest all the time to redo everything, again, to make sure everything is in good shape??
