Lights moving round Very slow - no Windows access

nineteen 1246356526|%e %b %Y, %H:%M %Z|agohover

Over the last few weeks my box has been getting into a hung state where it doesn't appear on the windows network, manual switch off via the front button does not appear to work.
Then on Sunday, after working fine for a few hours, I find I am unable to see it at all from Windows explorer.
The front LED's move round with exceptional slowness, changing every second or so
The outer ring goes full on, north only, none, all on, east only, none, all on, south only, none, all on, west only, none clocking round clockwise in this fashion, but only after I have tried to access it from windows explorer. Before that the LED's are all on static.

Can connect with SSH (Putty and WinSCP) - but very slow again - constantly timing out - this again is after I have tried to access it from windows explorer. (I must try SSH before accessing from windows - to see if it is faster)
top command indicates very small (< 5%) cpu activity

I have about 8% disk space free, and have web access to the manager - again snail like slow.
I stopped MIONET from starting months ago.

Has anyone seen these symptoms or got any suggestions on how to recover.

Thanks

Tim

Well top would have been my first recommendation but since there is not help there, then try to shutdown services one by one and check in /etc/crontabs/root to see if there are any odd jobs in there.

also what is the output of

cat /proc/mdstat

while ( love & passion ) {
for( fight = 0 ; rights < freedom ; rights++ )
fight = standup( rights );
free( babylon ); }

Thanks for the ideas. I should be able to try them out tonight.
What I will also try is connecting with ssh - BEFORE trying to access from windows explorer - or stopping Samba from starting up

I tend to get problems with mine when the disk drops bellow 10% free. The first sign is my lads computer (vista) starts to say the mapped drive is invalid and when I'm watching programs on my laptop it can take 2 attempts to start a vid playing, first attempt says "invalid file format," but shows the vid but without sound.

By deleting some files it all starts to work again ok.

That I was going to try too - some fairly large video files can go without missing them too much!

OK

etc/crontabs/root has no entries.

cat /proc/mdstat produces this
[root@Media /]# cat /proc/mdstat
Personalities : [linear] [raid1]
md1 : active raid1 sda1[0]
2939776 blocks [2/1] [U_]

md2 : active raid1 sda2[0]
104320 blocks [2/1] [U_]

md3 : active raid1 sda3[0]
987904 blocks [2/1] [U_]

md4 : active raid1 sda4[0]
484327552 blocks [2/1] [U_]

unused devices: <none>

Without accessing with windows explorer putty and WinSCP are very fast. Can read stuff, However, I'm having trouble deleting stuff
WinSCP returns

General failure (server should provide error description).
Error code: 4
Error message from server: Failure
Request code: 13

With putty I get (example)
cannot remove ‘30.Rock.S03E18.HDTV.XviD-LOL.avi’: Read-only file system

ls -al for this file reports
-rw-rw-rw- 1 www-data www-data 183515864 Apr 17 04:14 30.Rock.S03E18.HDTV.XviD-LOL.avi

What does it all mean?

Well from the look of the mdstat it would appear your raid is broken, maybe you have a bad disc. This is a dual hard drive model correct?

No - should have put that at the top - it's a single 500GB - been running for just over 2 years (disk just out of warranty!)

Elsewhere here people have reported the cannot remove ‘——': Read-only file system error and have tried disk check and reformatting of the MD4 partition.
Can someone point me at a step by step guide to doing this

I have to buy a USB drive for my son who's going to Uni, so if it comes to it I will copy off the contents (iTunes mainly) onto that and then try other stuff.

I don't know which is the more challenging - Solving this or playing Tomb Raider ?!

Well, tonight -without changing anything I have been able to delete stuff so the web interface reports 11% free
But - as soon as I go into windows explorer it slows down to a snails pace again.
Is this just a Samba or md3 issue?
What if I follow the instructions here?

How obscure can you get…
I was suspecting Samba of causing the problem, so from WinSCP, I went to /var/log/ and noticed there was a log.smbd.old version with dates up to last Sunday (went it all went Pete Tong).
I then tried to open the log.smbd file AND IT WOULD NOT LET ME!
Aha! I thought. So I renamed the file and rebooted the MBWE and it became visible from windows again

I realise that I probably have a disk error going on here, so I will work on plan B and try out MyBook Clone
If anyone has any further thoughts - Please let me know

Tim

The problem came back in a slightly different variant - but points at what others here have found with md3 or md4 getting errors.
What is the easiest way to clone the disk - when you haven't got a PC with SATA?
