Description Hans de Goede 2010-05-06 05:10:23 EDT
+++ This bug was initially created as a clone of Bug #589451 +++

Microsoft recommends using id 27 for recovery partitions:

And anaconda depends on parted to identify these partitions as such, so as to keep them out of grub.conf (see bug 534066).

However parted currently does not recognize an id of 27 as a diagnostics partition, that needs to be fixed.
Comment 1 Hans de Goede 2010-05-06 05:21:37 EDT
Note to QA: to test, create a msdos partition table with fdisk with a partition with an id of 27, then do
parted /dev/sda p

The output should show "diag" in the flags column.

Comment 6 Martin Banas 2010-05-14 02:38:15 EDT
Verified on build RHEL6.0-20100512.0 with parted-2.1-8.el6.

/dev/sda6 has ID of 27:
[root@ibm-js20-6 ~]# fdisk /dev/sda -l

   Device Boot      Start         End      Blocks   Id  System
/dev/sda6            4412        4864     3636192+  27  Unknown

parted shows it with DIAG flag:
[root@ibm-js20-6 ~]# parted /dev/sda print
Partition Table: msdos

Number  Start   End     Size    Type      File system     Flags
 6      36.3GB  40.0GB  3723MB  logical                   diag

Closing as VERIFIED.
