https://bugzilla.kernel.org/show_bug.cgi?id=100921 Bug ID: 100921 Summary: Kernel cannot read partition table automatically.But use partprobe command can. Product: IO/Storage Version: 2.5 Kernel Version: 4.1.0 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: SCSI Assignee: linux-scsi@xxxxxxxxxxxxxxx Reporter: halyx@xxxxxxx Regression: No I use linux kernel 4.1.0 in my Gentoo Linux. Whenever I insert my USB-HDD into USB-port, kernel cannot read the partition table automatically. But when I use the partprobe command, it can read my partition table. I want to know whether it is a bug. As the following, the output of the "dmesg|tail": dmesg | tail [ 5384.806237] usb-storage 1-4:1.0: USB Mass Storage device detected [ 5384.807159] scsi host8: usb-storage 1-4:1.0 [ 5386.440476] scsi 8:0:0:0: Direct-Access hp v250w 1100 PQ: 0 ANSI: 4 [ 5386.440660] sd 8:0:0:0: Attached scsi generic sg2 type 0 [5386.440899] sd 8:0:0:0: [sdb] 31506432 512-byte logical blocks: (16.1 GB/15.0 GiB) [ 5386.441314] sd 8:0:0:0: [sdb] Write Protect is off [ 5386.441319] sd 8:0:0:0: [sdb] Mode Sense: 43 00 00 00 [ 5386.441758] sd 8:0:0:0: [sdb] No Caching mode page found [ 5386.441762] sd 8:0:0:0: [sdb] Assuming drive cache: write through [ 5386.445789] sd 8:0:0:0: [sdb] Attached SCSI removable disk ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sda4 /dev/sda5 /dev/sda6 /dev/sda7 /dev/sda8 /dev/sdb As above, there is not /dev/sdbX(X=1,2,3...) Then, I use "sudo partprobe" ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sda4 /dev/sda5 /dev/sda6 /dev/sda7 /dev/sda8 /dev/sdb /dev/sdb1 As above, the /dev/sdb1 occurred. I want to know whether it is a bug.I didn't want to insert "partprobe" command whenever I use my USB devices.
