Hi all, As the web bugtracker seems to be broken I write this mail.
I'm using parted 3.2. All this was tested running a Debian jessie release within a virtual machine on Windows 8.1 using VMware Workstation 11. /dev/sdb is an USB cardreader physically connected to the Windows 8.1 machine and looped to the virtual machine. I was executing a script that does 'partprobe /dev/sdb' and immediatly after that 'dd of=/dev/sdb1 if=<something>'. The result is, that I get a regular file /dev/sdb1. After some more investigation I found, that after executing partprobe the partition files got removed and readded to the system. So running the script: root@debian:~# cat /tmp/test partprobe /dev/sdb while true; do ls -lad /dev/sdb1 done results in: root@debian:~# /tmp/test brw------- 1 root root 8, 17 Aug 15 16:39 /dev/sdb1 ls: cannot access /dev/sdb1: No such file or directory ls: cannot access /dev/sdb1: No such file or directory ls: cannot access /dev/sdb1: No such file or directory ls: cannot access /dev/sdb1: No such file or directory ls: cannot access /dev/sdb1: No such file or directory brw------- 1 root root 8, 17 Aug 15 16:39 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 16:39 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 16:39 /dev/sdb1 [...] brw-rw---- 1 root disk 8, 17 Aug 15 16:39 /dev/sdb1 brw-rw---- 1 root disk 8, 17 Aug 15 16:39 /dev/sdb1 brw-rw---- 1 root disk 8, 17 Aug 15 16:39 /dev/sdb1^C All the above is happing in way less then a second after executing partprobe. Thats a really odd behaviour. Then I downgraded parted to version 2.2 and ran the test script again: root@debian:~# /tmp/test brw------- 1 root root 8, 17 Aug 15 14:38 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 14:38 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 14:38 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 14:38 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 14:38 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 14:38 /dev/sdb1 brw------- 1 root root 8, 17 Aug 15 14:38 /dev/sdb1 [...] brw-rw---- 1 root disk 8, 17 Aug 15 16:39 /dev/sdb1 brw-rw---- 1 root disk 8, 17 Aug 15 16:39 /dev/sdb1 brw-rw---- 1 root disk 8, 17 Aug 15 16:39 /dev/sdb1^C This looks rather fine to me. Is this a bug? Or is partprobe 3.2 just running much faster than partprobe 2.2 giving the kernel no time to reread the partition table? Or something else? Kind regards, Bjoern
