[systemd-devel] systemd device appeared twice with different sysfs path

[李炎戌]

Hello, everyone!I am a newer to here.Recently, I have a problem.
Whenever I boot my gentoo linux, it output the infomation like following:
[   11.428530] systemd[1]: Device dev-disk-by\x2dpartlabel-Basic\x5cx20data\x5cx20partition.device appeared twice with dif
ferent sysfs paths /sys/devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sda/sda3 and /sys/devices/pci
0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sda/sda4

0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sda/sda6                                                         
[   13.085674] systemd[1]: Device dev-disk-by\x2dpartlabel-Basic\x5cx20data\x5cx20partition.device appeared twice with dif

0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0/block/sda/sda5


And the following is my /etc/fstab.
/dev/sda7        /        ext4        noatime        0 1
/dev/sda1        /boot/efi    vfat        defaults    0 0
/dev/sda8        /home        ext4        defaults    0 0
/dev/sda4        /mnt/software    ntfs        defaults    0 0
/dev/sda5        /mnt/data    ntfs        defaults    0 0
/dev/sda6        /mnt/backup    ntfs        defaults    0 0
/dev/sda3        /mnt/system    ntfs        defaults    0 0
The four NTFS partitions are my Windows disk partition.
The followint is my 'lsblk' output.

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 931.5G  0 disk  
├─sda1   8:1    0   200M  0 part /boot/efi
├─sda2   8:2    0   128M  0 part  
├─sda3   8:3    0  58.5G  0 part /mnt/system
├─sda4   8:4    0 195.3G  0 part /mnt/software
├─sda5   8:5    0 244.1G  0 part /mnt/data
├─sda6   8:6    0 244.1G  0 part  
├─sda7   8:7    0  29.3G  0 part /
└─sda8   8:8    0 159.9G  0 part /home
sr0     11:0    1  1024M  0 rom

The sda2 partition is a MSR(Microsoft System Recover) partition.
sda1 for EFI partition.
sda2 for MSR partition.
sda3-sda6 fro windows partition.
sda7 for gentoo linux root partition
sda8 for gentoo home partition.

Thank you!
Yours sincerely
