@f_l_a Just a quick notification that as of Rockstor version 3.8-14.07 testing channel updates we have improved nvme compatibility for the system disk. Noting here as you were instrumental in bringing this to the for, as you were one of the first reporters of issues around nvme and Rockstor. I know you have now re-installed on different hw for system disk and I think this is as well as there is still a little more to be done, ie why null serials entered the db with nvme devices but just to let you know. Oh and of course the in ability of Rockstor ‘as is’ to extract serials numbers from these devices; as you kindly researched. But just in case you were interested an in relation to the following:
in the related thread that I see you have also engaged with:
the original poster @snafu developed a set of working udev rules that not only attributes the required serial numbers but also sets up the now required by-id names for a single nvme device used as the system disk.
I still thing we may have a bug here prior to udev settings being applied as our db may still get a null serial which is no good but we will have to circle back around to that another time I think as it may just have been down to ‘in development’ udev rules. Not sure really. But the work around for the resulting db state is also available in the above thread.
Thanks for helping to encourage the nvme related fixes thus far and your examination of their serial issues.
