[caasp-beta] Resize / on CAASP

[Le Bihan Stéphane (AMUNDI-ITS)]

Hi,

After test is not works.

When I write partition :
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

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).

I test partx command after. But not ok only :

dl360o-100:~ # partx -u -n 2 /dev/sda
partx: /dev/sda: error updating partition 2

After drain node and reboot. All is ok.

Yes, that's a very old btrfs design bug ...

You can use any writeable part of the same filesystem.

In the end btrfs needs the device name, but the interface
does not allow that.
