Hi,
As USB attached SSDs are becoming quite big and affordable, along comes the
idea of installing systems on these.
But with current USB drivers, some functionality seems to be missing from USB
subsystem.
The system does not recognize it is an SSD, but it is corrected manually:
# cat /etc/udev/rules.d/10-forcessd.rules
SUBSYSTEM=="block", ATTRS{vendor}=="SanDisk", ATTRS{model}=="Extreme",
KERNEL=="sd?", ATTR{queue/rotational}="0"
# cat /sys/block/sdb/queue/rotational
0
Checked hdparm, it is saying I have TRIM on the device:
# hdparm -I /dev/sdb
/dev/sdb:
ATA device, with non-removable media
Model Number: SanDisk pSSD
(...)
Commands/features:
Enabled Supported:

* Data Set Management TRIM supported (limit 8 blocks)

[Kernel-packages] [Bug 1336541] Re: No TRIM via USB
The ASMedia bridges (as of the USB 3.1 Gen 2 ASM1351) simply does NOT
have UNMAP->TRIM implemented at all. It does support the "ATA
PASSTHROUGH" SCSI command, and it does not block TRIM on that, so hdparm
works.
The only one I've seen that supports UNMAP->TRIM is JMicron JMS567.
However, the implementation seems to be only partially done. Apparently
it does not support / has issue with queued UNMAP commands though
(assuming the uas driver in the kernel is doing everything right).
Therefore, blkdiscard/fstrim will work fine with the usb-storage driver
(`u` quirk), but will have issue with the uas driver on it.
Also, for some reason (maybe the aforementioned one), it has the LBPME
bit set to 0. So you need to change the provisioning_mode sysfs file
with `echo -n unmap` too (though that can be necessary anyway when the
usb-storage driver (u quirk) is in use, since it prefers Read Capacity
(10), which does not check the LBPME bit at all).
Unlike the ASMedia chips, it seems to block TRIM in its ATA PASSTHROUGH
btw.

[Kernel-packages] [Bug 1336541] Re: No TRIM via USB
TRIM is accessible via hdparm --trim-sector-ranges on a USB device
supporting ATA PASS THROUGH:
Device is an SSD in a USB 3.0 adapter identified in lshw as follows:
Bus 001 Device 005: ID 174c:55aa ASMedia Technology Inc. ASMedia 2105
SATA bridge
Adapter is hosting a 180GB Intel 530 M.2 NGFF SSD
fstrim fails as described with FITRIM ioctl failed: Operation not
supported even though the hdparm invocation works fine. I've tested
full ext4 filesystem trims using wiper.sh, the utility by Mark Lord that
was bundled for a while with hdparm until fstrim came out. This utility
works by wrapping the hdparm invocation.
So it definitely seems to be the case that the USB driver stack is
declining to implement TRIM even in cases where it is technically able
to do so. Given the extremely high performance of USB3+, it seems very
likely that USB-connected SSDs will become increasingly usual.

[Kernel-packages] [Bug 1336541] Re: No TRIM via USB
It seems that if the device is handled by the usb-storage driver, TRIM
is as of this writing unsupported and likely to remain so.
usb/storage/scsiglue.c sets skip_vpd_pages to true,
source/drivers/scsi/sd.c will not query for the necessary block limits to
support discard if skip_vpd_pages is true.
The bug poster should note per comment #1 in their dmesg excerpt that
their device is using the usb-storage driver
However, my Intel 530 SSD in the ASMT 2115 enclosure is acquired by the
uas driver rather than usb-storage. TRIM is not supported there,
possibly because of a failing in the bridge controller's translation of
the SCSI unmap method to ATA TRIM.
hdparm (and presumably blkdiscard, which I haven't tried) succeed
because they use ATA commands directly without going through a SCSI
translation layer either in usb-storage (disabled) or in the enclosure
firmware (possibly broken?).

[Kernel-packages] [Bug 1336541] Re: No TRIM via USB
Hi, provide my study here :-)
As far as I can see to support TRIM via USB bridge the USB bridge chip
MUST support SCSI / ATA Translation(SAT)'s ATA PASS THROUGH command in
order to pass the TRIM command to the disk.
Reading drive's S.M.A.R.T. data is similar to TRIM which they both
require working ATA PASS THROUGH command, you may checkout following
webpages for more info:
* [USB – smartmontools](https://www.smartmontools.org/wiki/USB)
* [Supported_USB-Devices –
smartmontools](https://www.smartmontools.org/wiki/Supported_USB-Devices)
and YES, external HDD closure's controller may not provide this
functionality, make sure to checkout the chip's datasheet before
purchasing any new one(while some may support this functionality via
controller firmware upgrade most of them don't)
However even you can read S.M.A.R.T. data using smartmontools utility,
TRIM is still (currently) not possible for unknown reason, might be the
usb-storage kernel module issue I guess.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.16 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not boot,
please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as
Confirmed.
Thanks in advance.

[Kernel-packages] [Bug 1336541] Re: No TRIM via USB
apport information
** Tags added: apport-collected trusty
** Description changed:
Hi,
As USB attached SSDs are becoming quite big and affordable, along comes the
idea of installing systems on these.
But with current USB drivers, some functionality seems to be missing from USB
subsystem.
The system does not recognize it is an SSD, but it is corrected manually:
# cat /etc/udev/rules.d/10-forcessd.rules
SUBSYSTEM==block, ATTRS{vendor}==SanDisk, ATTRS{model}==Extreme,
KERNEL==sd?, ATTR{queue/rotational}=0
# cat /sys/block/sdb/queue/rotational
0
Checked hdparm, it is saying I have TRIM on the device:
# hdparm -I /dev/sdb
/dev/sdb:
ATA device, with non-removable media
Model Number: SanDisk pSSD
(...)
Commands/features:
Enabled Supported:
(...)
* Data Set Management TRIM supported (limit 8 blocks)
* Deterministic read ZEROs after TRIM
(...)
Here is appropriate dmesg:

# fstrim -v /boot/
fstrim: /boot/: FITRIM ioctl failed: Operation not supported
# strace fstrim -v /boot/
(...)
open(/boot/, O_RDONLY)= 3
ioctl(3, FITRIM, 0x7fffdded85c0)= -1 EOPNOTSUPP (Operation not
supported)
(...)
During debugging, I've tried compiling a kernel with UAS module to
check, it booted, system was g changed with the trim - as it wouldn't
been used at all.
Any ideas why TRIM is not working on USB?
Any timeframes for possible fix?
Any workarounds maybe?
