post also the top headers values (load etc)

I that you've copied only 126 GB of data...

take a look at /var/log/messages too

sme 9 (CentOS 6.5) does not support direct upgrades from prior versions, so the only path to update an older version of sme server, is via backup & restore.

That is how I was going to try and do it, I had read that I had to do a fresh install.

Server manager restore panel should display the prgress of the restore & tell you when it is complete, I assume you instigated the restore via server manager & then server manager disconnected or you closed it (???).

Yes that is how I started it.  That is also why I am at a loss as to know when the restore has finished as I am unable to access server manager

I also notice that the headers seem to say that system has been up for only two days.  I started the restore on 27th.  Or does it say 2 days and 20:33 hours?

[Stefano]

ok.. let top run and take a look at wa (waiting) value..
I see it's 65%

that value should be as low as possibile..

Also show output of
cat /proc/mdstat

If your restore is nearing completion, then you may be best to just wait, assuming it is still running.

Sorry Janet I missed this request,  here it is.

 cat /proc/mdstat

Thank you for your help it is much appreciated.

Yes that's a lot of data to restore over a 100Mb network & not really practical to do so.

It may have hung & you are waiting for nothing. Use the tools Stefano advised to check what is happeneing.

You would be far better off (IMHO) to copy your backup off the workstation to a USB drive (locally connected on sme server formatted as ext3/4) to a correct folder location to suit the backup "layout", & then use that USB drive to restore from on the sme server.
That amount of data might typically take 8 - 10 hours to restore depending on various factors (USB speed, data type etc).

If I can find out that the restore has stopped I will do just that.  I do remember trying to attach a USB drive to the server before and not being able to get it to work, but I will try again.

What do you mean by: to a correct folder location to suit the backup "layout"

Thanks.

What do you mean by: to a correct folder location to suit the backup "layout"

When a backup is run say to a local USB drive (or workstation) it creates a certain folder structure, something like the server domain name, so if you manually move the backup file (only), then you need to create the same folder structure on the USB drive, so that the backup/restore function will correctly find the backup file.
The folder structure should be the samne as shown on your wporkstation backup share.

USB drives need to be formatted to ext3 or ext4, refer the Howto section of this site for details.

Oh I understand, thank you.

So when I get the USB drive working I guess I then have to mount the work station drive, that contains the backup, to the server manually.  Then I have to copy the backup files to the USB drive over the local LAN.

The restore does still seem to be running, but do you think I would be better off doing it the local USB route anyway?

TY again.

Stefano suggest you have only copied 126Gb, so you stil have a long way to go.
That has taken 3 days already so do you want to wait another 6 days or so ?
If something fails ie network connection, then all is lost.

You can reinstall the sme OS in 15 minutes, configure the backup in 5 minutes, transfer backup file in say an hour, then, start the backup which might finished in half a day or so, much quicker than waiting another 6 days in my books.

Your choice though.

It also seems to me that you do not have enough space on your sme server to restore that data
ie
Filesystem                          Size  Used Avail Use% Mounted on
/dev/mapper/main-root
                                        451G  127G  301G  30% /
/dev/md1                             99M   19M   76M  20% /boot
tmpfs                                  252M     0  252M   0% /dev/shm
192.168.7.4:smebackup
                                       932G  196G  737G  21% /mnt/smb

& you are trying to restore 737Gb (which is compressed) so more than that probably.

I am not sure if the actual size of the RAID 5 array is being shown.

[abarron]

Ok Janet I am going to take your advice and try and set up a USB disk.

I just realised I am guilty of a typo, the uncompressed data size is actually only about 350GB from memory.  Compressed should have been 250GB not 750GB.  That makes a significant difference but still only about half way through so I am going for USB.

If I can get that to work I will do my backups that way from now on.

Thank you for all your help, I really appreciate it.
