Subject: losetup on a image file containing (GPT) partition doesn't create partition devices
Date: Fri, 03 Oct 2014 11:44:32 +0200	[thread overview]
Message-ID: <542E7000.3040309@gmail.com> (raw)

Hello,

I have a disk image file which is using GPT and embeds 2 partitions.

I'm setting up a loop device with:

 $ losetup -P -f disk.img

and expect the partition devices (loop0p[12] for example) to be
automatically created.

During the loop setup, udev reposrts:

 $ udevadm monitor
 KERNEL[88697.611649] change   /devices/virtual/block/loop0 (block)
 UDEV  [88697.612488] change   /devices/virtual/block/loop0 (block)
 KERNEL[88698.738369] change   /devices/virtual/block/loop0 (block)
 UDEV  [88698.744727] change   /devices/virtual/block/loop0 (block)

The loop kernel module was loaded with max_part=16

The weird thing is that if I'm setting up the loop device using a blank
image file and create the partitions (using gdisk) on this loop dev, it
works.

I'm not sure if this is an issue to util-linux though and if it's not,
sorry for the noise.

Thanks.
