This week for the first time I toyed with OpenZFS on a USB device:
a mobile hard disk drive connected to the dock of an HP EliteBook
8570p.
A light test, with the pool imported but not writing to the
dataset at suspend time.
At resume time (22:31), the device was still physically connected
but the pool suffered an I/O failure (and the keyboard and
trackball on USB were unusable).
…
We need output from "procstat -akk" to see where ZFS/USB is hanging.
--HPS
For test purposes I reproduced the behaviour with a different
device, a USB flash drive (connected to the same dock).

Thank you

Hi,
USB is not hanging.
It looks like a problem with USB resume, that no devices are
recognized, until you re-plug them ...
--HPS
Hi
If I export the pool before suspend, no problem at resume time.
…
Please
Is there any way to avoid the need to export before suspending the
computer?
Might there be a future improvement to support for USB?
Thanks
