Summary: parted (v.2.3) does not create new /dev/ devices for newly created partitions (second and next) on RAID device Novell's Bugzilla: #715695 https://bugzilla.novell.com/show_bug.cgi?id=715695 Details: I have RAID0 device (MD) on two phisical disks. I have created 3 primary partitions on it. There were all 3 partitions in the partition table, but only one new device appeared in /dev/ filesystem (only for the first of
these three partitions). There is no related information in syslog. Defect concerns parted v.2.3 (parted v.2.1 works fine). Hardware Platform: x86-64 Operating System: SUSE Linux Enterprise Server 11 SP2 (SLES 11 SP2) Beta 4 Reproducibility: Always Steps to Reproduce: 1. mdadm -C /dev/md/raid0 -amd -l0 -n 2 /dev/sdb /dev/sdc -R 2. parted -s /dev/md/raid0 mklabel msdos 3. parted -m /dev/md/raid0 unit MB mkpart primary 1 1788 4. parted -m /dev/md/raid0 unit MB mkpart primary 1789 3576 5. parted -m /dev/md/raid0 unit MB mkpart primary 3577 5364 Actual Results: There is only one new device created for the first partition: /dev/md/raid0p1 Expected Results: There should be 3 new devices created for all 3 new partitions: /dev/md/raid0p1 /dev/md/raid0p2 /dev/md/raid0p3 Additional info: -------------------------------------------- Log of issued commands and their output: -------------------------------------------- address@hidden $ cat /proc/mdstat Personalities : [raid0] md127 : active raid0 sdc[1] sdb[0] 976771072 blocks super 1.2 512k chunks unused devices: <none> address@hidden $ parted -s /dev/md/raid0 print
