Public bug reported: Description: Ubuntu 16.04.1 LTS Release: 16.04
parted: 3.2-15 gparted: 0.25.0-1 Applications that utilized parted/libparted to probe for block device information disable the read only status during the probe. Example: Set a block device read only using either hdparm -r1 /dev/sdc* or blockdev --setro /dev/sdc*: # hdparm -r1 /dev/sdc* /dev/sdc: readonly = 1 (on) /dev/sdc1: readonly = 1 (on) Run gparted Check the readonly status with hdparm: # hdparm -r /dev/sdc* /dev/sdc: readonly = 0 (off) /dev/sdc1: readonly = 0 (off) The read only status has changed to off. This can be replicated using partprobe: Set a block device read only using either hdparm -r1 /dev/sdc*: # hdparm -r1 /dev/sdc* /dev/sdc: readonly = 1 (on) /dev/sdc1: readonly = 1 (on) Probe the devices using partprobe -s: # partprobe -s /dev/sda: msdos partitions 1 2 3 /dev/sdb: gpt partitions 1 2 3 5 4 /dev/sdc: msdos partitions 1 Recheck the read only status: # hdparm -r /dev/sdc* /dev/sdc: readonly = 0 (off) /dev/sdc1: readonly = 0 (off) As before the read only status has been switched off. Again, this can be replicated using parted: Set a block device read only using either hdparm -r1 /dev/sdc*: # hdparm -r1 /dev/sdc* /dev/sdc: readonly = 1 (on) /dev/sdc1: readonly = 1 (on) List the partition layout using parted -l: # parted -l . .
