I just upgraded to Rockstor Leap 15.4 using a new system drive (luckily).
It installed just fine but when I go to import the shares from my data disk, I get the following errors.
Houston, we’ve had a problem.
Failed to import any pool on device db id (3). Error: (Error running a command. cmd = /usr/sbin/btrfs
subvolume list -s /mnt2/share_it. rc = 1. stdout = [‘’]. stderr = [“ERROR: can’t perform the search:

To me, I think there is some sort of issue with the data disk.
I did test the whole drive with SpinRite and it shows no errors.
Is it likely some BTRS data issue?
Ummm, no expert here, but I have had the same problem and it was just I was trying to import from the wrong disk in a Raid-0 setup. I tried each disk and the last one listed worked…
I gave up on this install.
I installed 15.4 on another machine with 2 data disks and restored from an external NTFS volume I keep for just this kind of “emergency”.
So all is well, almost. I want to install 15.4 on the old server with the single 6TB drive. However, I need to get the data on this 6TB drive. I guess I’ll clean the drive and restore from my NTFS backup.
FYI, I just downloaded and installed the latest Rockstor Leap 15.6 distribution from USB stick on both my NAS setups “without disconnecting anything”.
I had to re-enable the rockon stuff for F@H and redo that bit, but went without a hitch.
The only glitch was using the GUI, it seemed disk page would error out when refreshing until I rebooted… then all was well. It did this twice on two separate disk pool imports.
Now, both setups running perfectly with Testing Updates activated and both running Leap 15.6.
Happy dude here! My main NAS setup went from 4.1 to 5.0.9 without having to disconnect anything.
