Can't create filesystem on disc -

eox425 · 2012-03-31 01:26:32

I'm trying to format disks to ext4 and reiserFS but after creating new partition table it fails.

cfdisking /dev/sdb
mkfs.ext4 /dev/sdb1

/dev/sdb1 is apparently in use by the system; will not make a filesystem here!

lsof | grep sdb1
echoes nothing

/dev/disk/by-uuid/ has nothing about sdb
but /dev/disk/by-id/ and /dev/disk/by-path has links to sdb partitions

Please give me advice...
I'm a udev noob with quite bad english.

What is the current fielsystem in the disc?
unmount the disc, if its mounted, and try again.

Have a look (with for example fdisk) on what partitions are already created on your /dev/sdb disk. If /dev/sb1 already exists, you can't create it again obviously.

I'm dd if=/dev/zero of=/dev/sdb bs=8M count=1
And udev deletes all partitions from the /dev
When I'm create a new ones with cfdisk I can't format them, or do anything.
There is no FS on empty partitions.

When you say it has empty partitions, I guess you need to create a partion table. Correct me if I am wrong.

Try rebooting the system after that dd command - it should get rid of any residual mounts..

Errm... I don't understand the exact issue behind the failure, but I would suggest trying this out via GParted as well? I have performed very many complicated disk operations through GParted, and it has never failed me.
