Public bug reported:
I recently upgraded from 17.10 to 18.04. After the upgrade, I noticed
that my Seagate Backup+ Hub external drive was displaying a series of
puzzling symptoms:
1. gsmartcontrol can't get SMART data from the drive. I am pretty sure
it used to report SMART data? Here's a log of it not working:
<warn> [hz] Warning: exit: Command line did not parse.
<warn> [app] execute_smartctl(): Smartctl binary did not execute cleanly.
<warn> [app] StorageDevice::execute_device_smartctl(): Smartctl binary did not
execute cleanly.
<warn> [app] SmartctlParser::parse_section_info_property(): Unknown property
"Physical block size"
<warn> [app] SmartctlParser::parse_section_info_property(): Unknown property
"Logical Unit id"
<warn> [app] SmartctlParser::parse_section_info_property(): Unknown property
"Temperature Warning"
<warn> [app] SmartctlParser::parse_section_data(): Unknown Data subsection
encountered.
<warn> [hz] Warning: exit: Some SMART command to the disk failed, or there was
a checksum error in a SMART data structure
<warn> [app] SmartctlParser::parse_section_info_property(): Unknown property

<warn> [app] SmartctlParser::parse_section_info_property(): Unknown property
"Temperature Warning"
<warn> [app] SmartctlParser::parse_section_data(): Unknown Data subsection
encountered.
2. hdparm used to be able to spin down the drive. I had it configured to
spin it down after a few minutes of inactivity, in the hdparm config
file. Now that no longer happens, and hdparm can't seem to talk to the
drive meaningfully at all:
[anovak@octagon ~]$ sudo hdparm -I /dev/sdb
/dev/sdb:
SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 00 00 00 00 24 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
I think this may be related to https://askubuntu.com/questions/1037997
/upgraded-to-18-04-usb-harddrive-doesn-t-idle-anymore which is someone
else having the same problem.
3. The ZFS tools think the drive is hosed:
[anovak@octagon ~]$ sudo zpool status hub
pool: hub
state: UNAVAIL
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from
a backup source.
see: http://zfsonlinux.org/msg/ZFS-8000-5E
scan: none requested
config:
NAME STATE READ WRITE CKSUM
hub UNAVAIL 0 0 0
insufficient replicas
ata-ST6000DM003-2CY186_ZF200PC8 UNAVAIL 0 0 0
This may be related to the drive having adopted a new /dev/disk/by-id
name during the upgrade? I think it was "ata-
ST6000DM003-2CY186_ZF200PC8" when I added it to my zpool by its symlink
under /dev/disks/by-id, but now it is "usb-
Seagate_Backup+_Hub_BK_NA8TQC87-0:0":
[anovak@octagon ~]$ ls -lah
/dev/disk/by-id/usb-Seagate_Backup+_Hub_BK_NA8TQC87-0\:0
lrwxrwxrwx 1 root root 9 May 31 20:52
/dev/disk/by-id/usb-Seagate_Backup+_Hub_BK_NA8TQC87-0:0 -> ../../sdb
This *shouldn't* cause trouble; you should be able to export the zpool
and re-import it under the new name. But zpool import shows nothing to
import:
[anovak@octagon ~]$ sudo zpool import
no pools available to import
And I also can't export or even destroy the busted zpool, because zpool
doesn't think it exists for exporting or destroying purposes:
[anovak@octagon ~]$ sudo zpool export hub
cannot export 'hub': no such pool or dataset
[anovak@octagon ~]$ sudo zpool destroy hub
cannot destroy 'hub': no such pool or dataset
4. The weirdest thing is that the drive itself seems to be working
correctly. I see /dev/sdb1 and /dev/sdb9, as expected for a ZFS drive. I
can `cat /dev/sdb1 | xxd | less` and see the data stored on the drive,
including what I think is the ZFS label (at 0x4000, with a bunch of
ZFS-y strings in it) that zpool is upset about not seeing. I see the
partitions in `gparted` just fine, too; there's no indication that
there's anything wrong with the partition table. Even the device's
integrated USB hub seems to be working fine. This is definitely not a
hard drive failure.
If I had to speculate, I would guess that the drive is being treated as a
generic USB mass storage device now, when it used to be being handled as a SATA
device in a USB-to-SATA enclosure (which I think it is). That would explain the
name change, and the difficulty that hdparm and gsmartcontrol have in talking
to it. The ZFS weirdness with not being able to export/destroy the pool has to
be another issue; it happens even when the drive is disconnected from the
system entirely.
