The articles explain the behaviour of high storage utilisation for /.mount partition when user-id process doesn't work properly because the file size of auth_v2.sdb.repl.sdb grows abnormally and this breaks the replication. As a result, the secondary node cannot sync user-id information with the primary node. Finally, the primary node gets stuck because no free storage space.
During the issue time ‘show system storage’ will fetch the below output and also the auth_v2.sdb.repl.sdb file size continue increasing.
user@root> show system storage | no-more
node0:
--------------------------------------------------------------------------
Filesystem Size Used Avail Capacity Mounted on
/dev/gpt/junos 100G 90G 2.8G 97% /.mount
tmpfs 8.3G 88K 8.3G 0% /.mount/tmp
tmpfs 2.7G 6.6M 2.6G 0% /.mount/mfs
user@root> file list /var/db/userid/auth_v2.sdb.repl.sdb detail
This KB also applies to the following file:-rw-r--r-- 1 root wheel 90G Dec 9 16:30 ./var/db/userid/dpt_v2.sdb.repl.sdb
Collect the output as per the below:
user@root> show system storage
user@root> start shell user root
Password:
user@root% df -h
Check for the higher file size with the below command from shell:
user@root%:~ # find / -size +100000
user@root%:~ # find / -size +1000000
You check file size using following CLI command:
In normal case, the file size will not reach 1 Gbyte. If the file size is larger than 1 Gbyte, please perform the following workaround.
Option-1:
1. Deactivate userid config using the command: user@root# deactivate services user-identification
2. Run CLI command on both node0 and node1: user@root> file delete-directory /var/db/userid recurse
3. Activate userid config using the command: user@root# activate services user-identification
Option-2:
1. Run CLI command on secondary node: user@root> file delete-directory /var/db/userid recurse
2. Perform RG0/RG1 failover
