 Posted: Sun Apr 18, 2010 11:13 am Post subject: Partition/Filesystem not recognized |
 |
|
Hi i am confused with a partition/filesystem problem. I just can't seem to format it in a way that will actually get recognized afterwards despite lack of error. I already tried ext2,3,4 and recreating the partition with fdisk and parted. What is going on?
| Code: | spax ~ # mke2fs -j /dev/sdb3
mke2fs 1.41.9 (22-Aug-2009)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
655776 inodes, 2622760 blocks
131138 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=2688548864
81 block groups
32768 blocks per group, 32768 fragments per group
8096 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 34 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
spax ~ # mount /dev/sdb3 /mnt/usb/
mount: you must specify the filesystem type
spax ~ # mount -t ext3 /dev/sdb3 /mnt/usb/
mount: wrong fs type, bad option, bad superblock on /dev/sdb3,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Kaste,
Being able to run | Code: | | mke2fs -j /dev/sdb3 |
does not imply that you have kernel support for the resulting file system.
Do you have ext3 support in your kernel?
If its a module, is it loaded?

have you tried unplugging and plugging in the usb stick after partitioning. I believe the kernel will then reread the partition data

Thanks for replying
Yes i have the support compiled into the kernel, I exclusively use ext and ntfs and ext isn't a module in any version.
I did try pulling it out and putting it back in several times, as well as issuing a partprobe. Nothing worked.
What else could be wrong?
I did do the formatting on a different computer now where it seems to have worked. I really need to understand this though since this will most likely not be the last time this will occur.
