| |
Hello,
I wonder why in 2013 I still cannot modify _unused_ partitions on the fly, yeah, the Internet is full of:
# hdparm -z /dev/sda
/dev/sda: re-reading partition table BLKRRPART failed: Device or resource busy
# fdisk (after adding a new partition using unused space on my hdd) ... Command (m for help): w
The partition table has been altered. Calling ioctl() to re-read partition table. Re-reading the partition table failed.: Device or resource busy
SCSI rescan command doesn't work too.
I do understand that the Linux kernel doesn't have any form of invoke() but then it prevents me from altering the partitions which are not used - it's 100% counter intuitive. Windows, for instance, allows to modify even a system partition on the fly since 2006, Linux doesn't allow to add partitions without rebooting the system.
Could anyone elaborate, please?
Best regards,
Artem
