F13: don't probe for RAIDs on CD-ROMs
Last modified: 2010-06-14 06:15:49 EDT
+++ This bug was initially created as a clone of Bug #588248 +++
Description of problem:
RAID probing of CD/DVD can yield errors because of well-known problem
in reading the end of the disk with some disk/drive combinations.
More information (upstream):
The problem is not possible to reproduce without the (broken) hardware, but it's possible to check that blkid(8) does not read from last sectors from the probed device. For example
strace -e read blkid /dev/cdrom
--- Additional comment from firstname.lastname@example.org on 2010-05-03 05:36:31 EDT ---
Note that you can also use
BLKID_DEBUG=0xffff blkid -p -o udev /dev/cdrom
to check that libblkid does not call RAID probing functions. (The -p should be also used tor the previous example with "strace".)
