i've looked everywhere, have already performed the system cleanup 

not sure where else to check under /var

nothing comes up as being overly large

configuration check succeeds

Hi ccarovich,

Could you please confirm what is the platform you have, as well share a couple of commands to double check,

root> start shell user root

root@RE:0% cd /var

root@:RE:0% du -cks * | sort -rn
root@:RE:0% find / -size +100000

ccarovich,

Please try to check the same but going into the member that is failing,

>request session member 2

>start shell user root

........

Something else you could try if there are no weird files found, is rebooting that specific member,

>request system reboot member 2

To avoid having a downtime of the whole stack.

Please marked as "Solved" if this worked for you

ccarovich,

In case you have no option to reboot I have found another possible solution,

From the shell mode of this member, same as before,

>request session member 2 

>start shell user root

%cd /var/rundb (check that you are on right directory with "pwd")

%ls | grep juniper. (if there are files matching, delete them)

%rm juniper.*

%mgd -I

If after doing this you are still not able to commit, please try with a #commit full force

Please mark as "Solved" if this worked for you

Hi Ccarovich,

I suspect harddisk is missing in FPC2 which not allowing the commit to get complete.

kindly refer below KB and perform the suggested action.

Please mark "accept as solution" if this answers your query. Kudos are appreciated too !
