Title
Adding a logic volume to physical volume(root volume) on oracle linux client machine using BMR live client for linux -
Description
While adding a logic volume to physical volume(root volume) on oracle linux clients (7.x,8.x etc ) using BMR live client for linux
we observe following messages in binary logs
"--backup because it is in a logical volume you did not select to include. You must include volume group vg_localon a system backup-- named semaphore initialization error: No such file or directory,backup failed on volume X" -
Cause
Installation of this plug-in on the NetVault Backup Server and each Linux Client also creates two additional directories on the machine:/storix/opt/storixThese directories contain Storix SBAdmin — a third-party DR boot utility application that is used by this plug-in to perform backups and restores. The data contained within these directories is required by this plug-in. Removal of these directories results in the inability to use the plug-in.When you install the Plug-in Live Client for Linux, two additional Storix directories are created — the Storix Bin directory and the Storix Temp directory.Adding a logic volume to physical volume(root volume) needs device_info addition as mentioned below -
Resolution
1 From the machine containing the installation of this plug-in, navigate to /opt/storix/bin:cd /opt/storix/bin2 At the command prompt, issue the following command to remove the remaining directories:./stuninstall3 Respond “y” to each prompt that is displayed regarding the removal of user configuration and history files.The following shows the screen output for these steps.# cd /opt/storix/bin# ./stuninstallIt will ask do you want to remove storix mention as yThe storix software is removed.Remove the live client plugin from netvault console on the linux clientRemove the /usr/netvault/util/linux directory by using the following command:rm -irf /usr/netvault/util/linuxRemove the README files by using the following command:rm -irf /usr/netvault/util/RE*Remove the /usr/netvault/util/stinstall directory by using the following command:rm -irf /usr/netvault/util/stinstallReboot the machine.Please create following directories in the client machine.- /storix- /opt/storixre-install live client plugin.When you install the plugin liveclient for linux, two additional directories created - the storix bin directory and the storix temp directory.The storix bin directory is where the storix software is installed.The default storix bin directory is /usr/binNote : Make sure to disable encryption on diskEdit this file: /opt/storix/config/device_infoComment out all line in the mpath section and only add the following lines:disk:mpath/mpath:a-z::1-15:Device-Mapper Multipath devicedisk:mpath/mpatha:a-z::1-15:Device-Mapper Multipath deviceThen restart netvault service on the client machine and re-run the backup. -
Additional Information
If additional logical volumes are added to the existing ones the BMR backup might fail
