Delete the host name of the slave server to be deleted from the connection authorization list file on the master server.
If replicated configuration is used for master servers, update and register the connection authorization list on the primary master server and then distribute to the secondary master server.
From the primary master server connection authorization list file, delete the CLIENT field of the slave server targeted for deletion.
Example
Removing the connection authorization for the slave server to be deleted
# cat /etc/pdfs/server.conf.1 <Enter> # # Copyright (c) 2012 FUJITSU LIMITED. All rights reserved. # # /etc/pdfs/server.conf.<FSID> # # List of client hostnames of a file system. # # Notes: # Do not describe hostnames of management servers. # # example: #CLIENT nodeac1 #CLIENT nodeac2 #CLIENT nodeac3 #CLIENT nodeac4 #CLIENT nodeac5 CLIENT slave1 CLIENT slave2 CLIENT slave3 <- Delete the row here. CLIENT slave4 CLIENT slave5 CLIENT develop CLIENT collaborate
Distribute the updated connection authorization list file to the secondary master server. (Only if replicated configuration is used for the master server)
# cd /etc/pdfs <Enter> # scp -p ./server.conf.1 root@master2:/etc/pdfs/server.conf.1 <Enter>
Note
If the contents of the connection authorization list file differ at different master servers, MDS-down recovery may fail and file system inhibition or system panic may occur.
