Last modified: 2013-04-03 08:07:54 UTC
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:19.0) Gecko/20100101 Firefox/19.0 Trying to install 12.3 x86_64. I have: * 2 NTFS partitions * hidden Windows 7 system partition * one EXT4 * one SWAP The DVD installer starts fine, but while the probing step of "Looking for existing linux partitions...", at 60%, it gets stuck, and no HDD or DVD activity is visible on my PC. I had to wait about 15-20 minutes until the scanning was complete. One more user has reported this kind of behavior. Following openSUSE topic describes this case: https://forums.opensuse.org/english/get-technical-help-here/install-boot-login/485066-installation-gets-stuck-while-scanning-hdd-partitions.html Reproducible: Always Steps to Reproduce: 1.run installation 2. 3. Actual Results: installation gets stuck for 15-20 minutes at partition scan Expected Results: partition scan should take about 10-15 seconds, according to virtualbox experience

I had a look at the log file and saw that some external commands we call during fs detection is extremely slow: We call the command "/sbin/blkid -c /dev/null" it needs 562 seconds to finish in addition an "/sbin/mdadm --examine --scan --config=partitions" needs 55 seconds. Both commands typically need less than a tenth of a second to complete. Please try the following command: strace -tt /sbin/blkid -c /dev/null 2> strace.output And attach the generated file strace.output here. It should display which system calls delay the command for such a long time. If you do not have command strace installed, you can install it with "zypper in strace".
I had a look for similar problems and it look like it could be the same as in bnc#773058
Created attachment 532644 [details] sudo strace -tt /sbin/blkid -c /dev/null 2> strace.output
This call of blkid was not delayed, it needed 0.4 seconds to complete. We need the output of a strace call where the delay happens. Maybe the delay happens only in installation environment. If yes could you boot into install environment and recreate the strace output.
I have disabled the floppy support inside the BIOS, set to NONE, and the installation went nice and fast. I guess this bug can be marked as duplicate of #773058. Thanks everyone.
