Hello, We use parted in ceph-ansible playbook [1] to retrieve some devices information, the parted ansible module runs a parted/print command [2], but we are facing an issue where ownerships get modified after that.
Doing the test manually without ansible context shows it's parted itself which apply this change: Before running parted on /dev/sdc: [root@osd0 ~]# ls -l /dev/sdc* brw-rw----. 1 root disk 8, 32 Jun 11 08:53 /dev/sdc brw-rw----. 1 ceph ceph 8, 33 Jun 11 08:53 /dev/sdc1 brw-rw----. 1 ceph ceph 8, 34 Jun 11 08:53 /dev/sdc2 Running a basic parted/print: [root@osd0 ~]# parted -s /dev/sdc print Model: ATA QEMU HARDDISK (scsi) Disk /dev/sdc: 53.7GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 1075MB 1074MB ceph block.db 2 1075MB 2149MB 1074MB ceph block.db We can see ownerships have changed from ceph:ceph to root:disk: [root@osd0 ~]# ls -l /dev/sdc* brw-rw----. 1 root disk 8, 32 Jun 11 08:57 /dev/sdc brw-rw----. 1 root disk 8, 33 Jun 11 08:57 /dev/sdc1 brw-rw----. 1 root disk 8, 34 Jun 11 08:57 /dev/sdc2 [root@osd0 ~]# I'm wondering whether there's a good reason for this or should it be considered as a bug? Thanks!
