Hi to all,

I need your help. I have googled a lot and nobody seem to have my problems.

I have a Banana Pi M1 running Bananian since June with Samba, Transmission, Munin, Monit, Webmin, OpenVPN. No problems so far.

I have experienced a power failure and now I have strange behaviors:

1. Samba, OpenVPN and Transmission servers stop working
2. Cannot login with SSH (see below)
3. Cannot not open a terminal in the GUI (blank terminal, no prompt)
4. DF command not working anymore (see below)
5. File /etc/mtab is empty

Errors while trying to login with SSH:

Server refused to allocate pty
stdin: is not a tty

Error with the command DF:

df -h
df: cannot read table of mounted file systems

Mount command show no output

File /etc/mtab is empty

File /etc/fstab has this:

cat /etc/fstab


# 512 MB swapfile
/swapfile1 swap swap defaults 0 0

UUID="A214C52A14C50271" /mnt/USB1800GB/ ntfs nls-utf8,umask-0222,uid-1000,gid-1000 0 0
UUID="3880832A8082EDA6" /mnt/USB1400GB/ ntfs nls-utf8,umask-0222,uid-1000,gid-1000 0 0

Version running:

uname -a

Linux NAS 3.4.111-bananian #5 SMP PREEMPT Fri Mar 25 17:24:42 UTC 2016 armv7l GNU/Linux

Cannot see what is running with PS command:

ps -ef
Error, do this: mount -t proc proc /proc

Partial solution:

Command "mount -t proc proc /proc" seem to bring back everything because I can use DF and PS after running it.

Now I see that:

/dev/mmcblk0p2 on / type ext4 (rw,noatime)
devtmpfs on /dev type devtmpfs (rw,relatime,size=496748k,nr_inodes=124187,mode=755)
sysfs on /sys type sysfs (rw,relatime)proc on /proc type proc (rw,relatime)

df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root        29G  2.3G   26G   9% /
devtmpfs        486M  4.0K  486M   1% /dev

cat /etc/mtabrootfs / rootfs rw 0 0/dev/root / ext4 rw,relatime 0 0

sysfs /sys sysfs rw,relatime 0 0proc /proc proc rw,relatime 0 0

But if I reboot, the problem come back.
How can I solved this ?
Thanks in advance.

SD card might be corrupt. Try to restore the system from a previous backup to a new SD card.

If you are buying a game for your children (or another child you know) discuss the purchase with them first. Don't just buy on a whim. Sports games are quite different from RPG games, so if they have a particular interest, you want to make sure that you know what that is.

Please give me an idea about the problems after the power failure and everything was well explained which help me to understand the content in a better way so we are hoping to see many more such helpful content on your page when international travel resume
