-bash: /dev/null: Permission denied

it is not first case - it is occurs sometime (maybe after similar errors)
at this moment /dev/null is:
| Code: |
stat /dev/null
File: ‘/dev/null’
Size: 0 Blocks: 0 IO Block: 4096 regular empty file
Device: 5h/5d Inode: 25618161 Links: 1
Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root)
Access: 2016-09-28 23:59:10.987234481 +0300
Modify: 2016-09-29 00:02:13.982933913 +0300
Change: 2016-09-29 00:02:13.982933913 +0300
Birth: -
|
to restore I use this (not sure that is right - please correct my code):
| Code: |
cp /dev/null /tmp/zero-dev.save
rm /dev/null
mknod /dev/null c 1 3
chmod 666 /dev/null
|
after this /dev/null is:
| Code: |
stat /dev/null
File: ‘/dev/null’
Size: 0 Blocks: 0 IO Block: 4096 character special file
Device: 5h/5d Inode: 25633703 Links: 1 Device type: 1,3

Is it this commands enough?
Is it safe to reboot now?
emerge --info:
https://paste.pound-python.org/show/Z2ip8rHVL7lEeFsyHWKY/
please try to fix if it portage related error
thanks |

modnaruved,
That looks fine, if that's the real problem.
/dev should be mounted as a devtmpfs filesystem. Them its recreaded by the kernel every boot and maintained when devices are added/removed.
Its possible that /dev was unmounted, showing you the static /dev underneath. This static /dev could have been corrupted some time ago.
The reboot should create a whole new /dev for you.

Thanks for answer
How can I check that my /dev is mounted as a devtmpfs filesystem?
my /dev now (still don't rebooted):

Look at | Code: | | mount | grep devtmpfs |
And please change /dev/null (and /dev/console) not in a running system (or a chroot).
If it needed, do it from a LiveCD, mount your / Partition to /mnt/gentoo
and remove the old, and create it new with
mknod -m 600 /mnt/gentoo/dev/console c 5 1
mknod -m 666 /mnt/gentoo/dev/null c 1 3
sync
umount /mnt/gentoo
reboot
It should work :) |

modnaruved,
Your dev entries were mostly created on 20 Sep, but not null, which dates from the fix,
| Code: | crw-rw-rw- 1 root root 1, 3 Sep 29 00:12 null
crw------- 1 root root 10, 144 Sep 20 19:57 nvram |
We also see that | Code: | | brw-rw---- 1 root disk 8, 7 Sep 27 20:13 sda7 |
, so you added sda7 at that time and the /dev node wan added too.
My /dev dates from my install date, May 12 2013. I know I have a static /dev as that was a deliberate decision on my part.

sda7 is just swap: sometime (but not at Sep 27) I do this:
| Code: | | sudo sh -c "swapoff -a ; swapon -a" |
to reset performance and memory issues
I don't know why my dev not in install date. How to fix it or check what change it?
my fstab and mount:
| Code: | # /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.

modnaruved,
| mount: | | devtmpfs on /dev type devtmpfs (rw,nosuid,relatime,size=10240k,nr_inodes=685256,mode=755) |
Your /dev is not supposed to be on your install date. The above fragment shows devtmpfs in use, so your /dev is recreated in RAM each boot and then dynamically maintained.

Suppose, most users has similar configuration as mine, but in my case Gentoo is installed approx. in 2014 |
