[SOLVED] Using mkfs to format device

ethereal1m · 09-15-2010, 04:29 AM

Dear all,
I'm trying to format a device into XFS filesystem using mkfs command. Suppose I have a /dev/sda1 device with 4096 block and I want to format the whole thing, how can I execute the command? I keep getting various errors while executing it...

Regards,

Hi,
we'll need to get the commands you tried and the errors you got to be able to help you. I suspect however that a quick read of the man page should help solve your problem.

I read the manual.
Ok last time I tried:

Code:

mkfs -t xfs -b size=4096b /dev/sda1

I got:

Code:

blocksize not available yet

That is one one them... any suggestion?

According to "man mkfs.xfs" your command is not correct.

hm, when I do

Code:

mkfs.xfs /dev/sda1

I got

Code:

agsize (2008b) is too small, neet at least 4096 block

when I do

Code:

mkfs.xfs -d agsize=4096 /dev/sda1

I got

Code:

blocksize not available yet

Any idea?

but when I do

Code:

mkfs -t ext3 /dev/sda1

this works, how come?

Something strange is going on because the default block size is 4096.

ok this is my bad, this

Quote:

default block size is 4096.

makes me realize that I partitioned the device incorrectly (it was 8M size space).

Thanks for the help
