Anyone can advise what happened

Hi,

Try to apply the commit from the config prompt.  Enter cli at %, enter configure, then try to commit.

Great, it worked , Thank you

It sounds like you have run into the PR/460909 caveat.  JUNOS release 9.3S6, 9.5S4.1, and 9.6S2.1 are the latest releases for the 9.3, 9.5 and 9.6 trains respectively as of this posting.  I hope included references are helpful.  

The first publication that I noticed the PR/460909 caveat being published was PSN-2009-07-461.

Hi,

Did you see this KB?

Can you please tell me how did you run into this? Was it after upgrade?

Thanks,

Pls guide

Hey there,

 I'm not exactly sure what went wrong, but you can fix this easily by dropping into the shell as root (start shell root) followed by the command "mkdir /var/db/config/"

Cheers,

Pls check and comment

root@-SW:RE:0% mkdir /var/db/config
mkdir: /var/db/config: File exists
root@-SW:RE:0%

is there already a symbolic link perhaps?

It could be a typo while following the previously referenced KB with an invalid pointer, which could explain the error.

Cheers,

Sorry i didnt get you , if you can explain what "" symbolic link "" you are pointing to.

I had this issue on EX-8208 with dual RE and as per KB24760 implemented the workaround but it did not help me... I was still getting the commit sync problem.

The current Junos version is 10.1R1.8. The workaround mentioned in earlier posts or the KB does a soft linking but when it did not work for me, a hard link will be done as per Linux process.

Now the switch is taking 'commit sync' command wihtout any issue.

the workaround mention that the db/config did not exist initially and when the soft linking was done, it gives in output.

user@switch>start shell user root
user@switch%
user@switch% ls -ld db/config

ls: db/config: No such file or directory

user@switch%

In my case. this file was already created and so, gave the alert as 

root@OKH-EX8208-SW1:RE:0% ls -ld db/config
lrwxr-xr-x 1 root wheel 17 Mar 24 2010 /var/db/config -> /config/db/config
root@OKH-EX8208-SW1:RE:0% cd /var/db/
root@OKH-EX8208-SW1:RE:0% ln -s /config/db/config . 
ln: ./config: File exists
root@OKH-EX8208-SW1:RE:0% ln -s /config/db/commits . 
ln: ./commits: File exists

Why is this so?? This workaround this did not work for me in spite of its exact match with my issue.

user@switch>start shell user root
user@switch%
user@switch% ls -ld db/config

You are in /var/home/user folder. Command "ls -ld /var/db/config" should be the one you expected. Try "cd /var/db" and see if it works.

/Charlie

Ckim, the /var/home/user is visible in the workaround excample which JTAC has mentioned in their KB but I have tried with the /var/db/config directory but it didn't help me either.

You may go through the log file attached in my post... Please suggest if you find something there..

Pardon my ignorance here, and I truly when it comes to linux file system, but any special reason why the files stored in the directory "/var/db/config" need to be linked to "config -> /config/db/config"

error copying files (/config/juniper.conf.3.gz->/var/db/config/juniper.conf.4.gz): No such file or directory

/config/db/config

error: remote commit-configuration failed on re1

config -> /config/db/config

I think the way you are creating a link is making the system thinks the link is back to the same directory hence it creates an infinite loop when it does the path lookup. If you simply remove any links you have created and allow the system to do its own thing, does it work? Also >show log dcd, it may have something in it too.
use the command rm -r /path/folder to remove the symlinks you have created then test it.

I have the plan for upgrade but the upgrade process may require the commit sync command at some instances so I want to resolve the issue first and then go for the upgrade.

If JTAC has given some workaround then I expect it to work. Shouldn't we?
