Can not read files from samba

[86ivar]

Hi.

I can view the filesystem of bubba2 in windows samba but i can not read or copy the files.

Theres about a hundred reasons why that could be. Please show some respect to the people who volunteer to help you by explaining the issue in more detail.

Sorry for beeing disrespectful, I think i lost some of the text somehow in the first post.
To fix the problem i tried, in chronological order:
-Turn of and on windows fileshare. After this i get to see the \\b2 folder with home and storage folder. But now when i try to open them i get the message that \\b2\storage is unavaliable.
-Tried a update and a restart.
-Turned the unit off, unplugged everything and waited a minute before turn on.
It is still dead, can not reach from my pc nor my pad.

Sorry if I missed something. Havent done any system changes lately.

Can you access via the ip address?

Well my unit started acting very strange toda, claiming no more space on hdd. But i have 200gb free on 2tb hdd. Got some error reportings in the web interface. Now I have done a reinstall and samba is atleast working fine

ah a full disk would explain the behaviour. As mentioned, there are many reasons why your observed behaviour could occur. In your case your root partition was full (your 200GB free was your home partition), most likely due to oversize log files or unroutable email. Re-installing would not have been required.

Hmm how do i delete the extra stuff then? I have never used the email service, seems a bit odd to fill 9+ gb with log files

Again, theres a lot of reasons why the drive can fill up, and you did not provide a lot of info. In the linux shell there are a few tools to investiate drive usage, such as "du" and "df".

So I got the problem agin (hdd full). I think it appears when i disconnect the hdd where i send the backupfiles, so the backupfiles end up in bubbas filesystem. I found some strange folders in root (./.cache/duplicity/ ), I deleted tham and i had free space agin. But soon after I got the problem once agin. So now I deleted the whole logfile folder. When i df I get

The /dev folder is a virtual file system used by Unix-like systems as an easy way to access hardware as if they were files.
They are not really files.
The same goes with /proc.

/dev/sda1 is the first partition of your HDD, and it corresponds to / (the root file system)
/dev/mapper/bubba-storage is the representation of the LVM file system that takes up the rest of the disk.
All the other stuff you see in there represents things as USB ports, network cards, etc.
In other words: ignore it.

Your df output shows that the first partition (/) is full. This is where the OS lives, and nothing much will work if it cannot write log files etc.
You need to find out what's filling it up.

This, I have never seen before:

Code: Select all

overflow                  1024         0      1024   0% /tmp

Could you please provide the output of the following?

Code: Select all

# du -h --max-depth=1 /tmp
# cat /etc/fstab

[86ivar]

# du -h --max-depth=1 /tmp:

Code: Select all

usbfs   /proc/bus/usb   usbfs   defaults        0       0

The external disk you see here is disconnected. I dont remember if i unmounted it in web interface or not before i moved my bubba to another place. Turned bubba off properly though.

It looks like a mess.
I'm not comfortable in advising you with things that could possibly cause loss of data, but here is what I would do (follow only at your own risk):

1. Boot the B2 with the rescue stick and connect to it via ssh

2. Mount /dev/sda1:

Code: Select all

# mount -t ext3 /dev/sda1 /mnt

3. Edit /mnt/etc/fstab and get rid of all that crap. Here is /etc/fstab from a fresh B2 install:

Code: Select all

/dev/sda1	/	ext3	noatime,defaults	0	1
/dev/mapper/bubba-storage	/home	ext3	defaults		0	2
/dev/sda3	none	swap	sw			0	0
usbfs		/proc/bus/usb	usbfs	defaults	0	0
/proc		/proc	proc	defaults		0       0

4. When you have booted with the rescue stick and mounted /dev/sda1 you have the chance to examine the true directory structure of the partition, so now you can find out what is really filling it up.
Look at /tmp:

Code: Select all

# ls -la /mnt/tmp

It should be empty. No files are supposed to be stored in there, it is a mountpoint only.

If /tmp is not the culprit, look at other things like /var/log. Try using du.

Did a complete reinstall just as last time, but no formating or partition so i did not loose data. Figured out it was the best to the fact i deleted the log files. FTP was'nt working...
Anyway thank you for helping.

[86ivar]

I will be away for approx a year nor. My b2 will be in a server room. If it will start acting strange again, will it be possible to rescue it with the usb stick by shell? Could also just reinstall it, would be cool, but then i have to preset the easyfind so i can find it after reinstall. Any idea?
