Subject: [Bug] Remove and add a mounted device gets a new dev path
Date: Sat, 08 Dec 2012 01:13:24 +0800	[thread overview]
Message-ID: <50C223B4.8050301@oracle.com> (raw)



# mount /dev/sdb /btrfs

# echo "scsi remove-single-device 1 0 0 0" > /proc/scsi/scsi

# lsscsi
  [0:0:0:0]    disk    ATA      VBOX HARDDISK    1.0   /dev/sda
  [2:0:0:0]    disk    ATA      VBOX HARDDISK    1.0   /dev/sdc

# btrfs su create /btrfs/sv1
Create subvolume '/btrfs/sv1'
ERROR: cannot create subvolume - Input/output error

# echo "scsi add-single-device 1 0 0 0" > /proc/scsi/scsi

# lsscsi
[0:0:0:0]    disk    ATA      VBOX HARDDISK    1.0   /dev/sda
[1:0:0:0]    disk    ATA      VBOX HARDDISK    1.0   /dev/sdd <---
[2:0:0:0]    disk    ATA      VBOX HARDDISK    1.0   /dev/sdc

The same disk comes back as /dev/sdd

(the issue is same if disk is mounted as an ext4 fs)

Thanks
