Inconsistent mount point on Banana Pi Pro over SATA

Armbianmonitor:

The info from "df" show /dev/sda but "lsblk" show a /dev/sdc unmounted unit. The unit is reachable at /media/sata and is added in fstab using the UUID.

What's happening?

Thanks in advance.

block device names can vary especially on USB.... it's best practices to use UUIDs or LABELS to mount filesystems.

I used UUIDs to mount via fstab. You can see it in the snapshot and I suppose this info is also included in armbian-monitor dump included.

Still odd nevertheless. One a block device is assigned it should be consistent across those very basic commands, shouldn't it?

okay sorry I didn’t understand the issue exactly.

 

so I believe this is a technicality of using lsblk.   A btrfs subvolume isn’t going to trace back to a block device.   Would be interesting to look at the output of 

 

ls -l /dev/disk/by-uuid

After mounting and unmounting several times both external units it seems to start working. Now the mount point at /sda is consistent across all the commands. The outpus you asked, @lanefu, is:

ls -l /dev/disk/by-uuid 
total 0
lrwxrwxrwx 1 root root 15 may 11 22:57 d4e4d15d-d587-4f5d-83d7-4cbb1700e7c5 -> ../../mmcblk0p1
lrwxrwxrwx 1 root root  9 may 11 22:57 dcb5a19c-6bd2-4c5a-8fc4-9ed4adec7074 -> ../../sdb
lrwxrwxrwx 1 root root  9 may 11 22:57 e6201983-bfd8-4eae-bf54-90575f09835f -> ../../sda

 

I also added a new screenshot. Thanks for the help. And I'll keep an eye on this if it happens again.
