Hello,

yes that will work. You need to check the interface config of course
(because you have less interfaces).

The M20 will install the correct PFE module when it loads (it will spit
out an error saying its running the incorrect PFE module for this
architecture). So booting will take a minute longer than usual but thats
it.

Hi experts,

Thanks for your replies and advices.

Just a quick question, as we have an old M5 and M10, we were wondering
if we could replace directly the HDD from one of these two routers to
our M20. Is it that possible? any experience doing that? If both of
them have the same JUNOS installed, and then copy the current
configuration..  thoughts?

Many thanks,

Hello,

havent you changed the HDD yet? Like to live dangerously eh? :-)

This is very likely related because those errors messages causes writes
to the HDD....and if your HDD is dead/has bad sectors that will cause
trouble.

Good luck,
Jonas

Could you put them both in a Linux box and just 'dd if' them?

Dear Isidoro,

you cant copy the data 1:1....atleast not without alot of work.
The best thing would be if you reinstall JunOS via a install media (pcmcia/cf 
card) once you replaced the hard disk.
Its very easy to replace the hard disk on either RE2/3/4/5...its normally only 
secured by 4 screens on the RE.
Make sure to save your config files (JunOS config, SSH keys, other data like 
home directorys, logs etc) before you replace the HDD if neccessary.

Best regards,
Jonas

Hi,

First of all thank you very much for your quick response .

How to save the data to the new hard disk? Do you know a procedure for
replacing hard disk ?

Best Regards,

Isidoro

Hi,

you are correct, the disk exceeded the maximum write errors
permitted by the SMART value and thus is marked as bad. Prepare for
a complete failure of the drive soon (1-30 days likely).
May be the right time to upgrade the harddisk to a SSD.

Hi all,

    From yesterday at the log of my M20 are the following message :

           smartd[2595]:  Device: /dev/ad1a, Failed attribute: (200)Write
           Error Rate

It´s informative, but i think that there is a problem with my HDD (
I still have to run the smartd commands ) .

Somebody had this problem ?


Best Regards

Isidoro
