Hi all,
I have a piece of kit that has SUN CP2040 boards and it's mobile.
The problems arise when it gets powered down in the field in an
uncontrolled manner. It corrupts the /etc/name_to_major file.
I can re-create this problem every time. It's when a driver get's loaded
to a custom PCI card, for a few minutes, firmware is loaded to the card.
During the firmware load, the box is vulnerable.
Now i know i've mentioned the corrupt /etc/name_to_major before; but
i've just discovered that i cannot replicate this problem if i DISABLE
UFS LOGGING.
my thinking is; the name_to_major file is updated but held in the UFS
logging's cache.
If tried adding a "lockfs -f" to flush the cache but i still get
corruption on the file.
Can anyone offer any advice on controlling the UFS logging??
are there any parameters to tune etc.....
Thanks.
