After last kloxo update, my server broken!

[MRatWork]

It's hard to backup in rescue mode.

[NetMajom]

I have attached my hdd to the system in rescue mode, and i can connect to it via winScp, so i see all the files. What do you think the CTRL + C and CTRL V is working if i setup a new system?

[MRatWork]

Didn't understand about 'What do you think the CTRL + C and CTRL V is working if i setup a new system?'.

For your issue, it's related to grub.

[NetMajom]

Yes, i think the grub is not working in my system, but i dont know how can i repair it with an attached hdd..

(I mean copy paste, that i copy all the system to my laptop, after when a new centos system installed, i paste it all)


But do you know any way that how can i repair a grub in an attached hdd?

So, the md126 is missing. maybe thats the problem? what do you think?

[MRatWork]

So, ask to your provider to replace hdd.

[NetMajom]

They say, the hdd is good. Do you know any linux command what i should present/show to my provider? Because they want proof from me that hdd is broken, to replace the hdd.

[MRatWork]

Use smartctl like http://superuser.com/questions/585510/how-close-to-death-is-my-linux-hard-drive

[NetMajom]

sadly the HDD'S has good condition
