Sometimes i get the
"mount: operation not permitted" error message if i want to mount a partition on the desktopbsd laptop (codenamed jaguar).
If i look at
dmesg i’ll see that it’s failing due to the partition not being clean, something like:
"WARNING: R/W mount denied. Filesystem is not clean - run fsck"
Most common cause is a fault in previous umount’ing (last night it drown out of battery).
Did the obvious thing, and fsck (
# fsck ) showed what was wrong.
EDIT: after running fsck, you’ll have to run it again on the specific partition, until fsck marks the partition as clean.
So, i’ve also edited /etc/fstab and changed the 6th field for that mount point to 2 (was 0). So, on the next boot, it will check for consistency and if its clean it will skip the full verification. Which in my case wasn’t and took a couple of minutes to clean it.
from man fstab
The sixth field, (fs_passno), is used by the fsck(8) program to determine the order in which file system checks are done at reboot time.[…]
If the sixth field is not present or is zero, a value of zero is returned and fsck(8) will assume that the file system does not need to be checked.
as always, there’s a nice article on this in the free bsd diary
On a complementing note, it was nice to note that there are bz2 of previous messages from the system (the messages file), a dmesg.today and a dmesg.yesterday. I have to make my gentoo do something similar if i ever want to find out what is causing the kernel panics.
