Hello
I just formatted a disk from terminal: I deleted the old partitions, created the new ones and saved the changes.
In the end, I got the following warning, which I guess is pretty normal:
Quote:
WARNING: Re-reading the partition table failed with error 22: Invalid argument.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)
|
To be sure, I rebooted and I've been able to format the disk with mkfs.ext4, apparently without any problem, since the disk mounts correctly as ext4 and seems to work fine.
What bothers me is this:
Code:
root@Sheevaplug:~# fdisk -l /dev/sda1

For some reason, fdisk -l still shows the old file system, while printing the partition table shows the correct one.
I guess is because the kernel doesn't use the new partition table, but rebooting didn't help and neither did giving partprobe. If I give partprobe /dev/sda1, I get this:
Code:
root@Sheevaplug:~# partprobe /dev/sda1
Error: Error informing the kernel about modifications to partition /dev/sda1p1 -- Invalid argument. This means Linux won't know about any changes you made to /dev/sda1p1 until you reboot -- so you shouldn't mount it or use it in any way before rebooting.
Error: Failed to add partition 1 (Invalid argument)
If I run partprobe without arguments, it doesn't give any error, but still doesn't solve the problem.
What is wrong?
The system is actually an external hard drive connected through eSata and no operative systems are on it.
