I'm claiming this bug for myself since I know about os-prober and have
other grub/os-prober updates in flight. Targetting to ubuntu-17.01.
Is this HTX thing doing read/write operations directly on the disk, or
does it use a filesystem? Is it using a known filesystem or its own
format?
"This caused write fails for sda1, sdb1 disks along with nvme disks and
also logged Linux errors."
Do you mean write errors as reported by HTX?
The os-prober errors listed are just cosmetic, caused by the fact that
os-prober, when run (this is run by grub/update-grub to detect possible
other OSes on the system), will "probe" the filesystems: first detecting
the available partitions, then attempting to "mount" them to finish
probing. This is normally done by "grub-probe" and "grub-mount", which
should be relatively safe, but also *had* another code path to use
straight "mount" which has shown issues (a fix is available in xenial-
proposed for it, should be made available in updates soon).
What version of os-prober do you have installed on this system? (use
dpkg -l os-prober)
If all else fails, we could disable os-prober altogether; there's
another fix coming up that does so on PowerNV due to the effect on
Petitboot.
