NVE: How to Increase "data01" Partition Size

Sizing and scaling information can be found in the NetWorker Virtual Edition Deployment and NetWorker Performance Optimization Planning Guides available through Dell Support NetWorker Product Page.

To identify the file system type of the NVE, run the following command from an SSH session: 

/dev/sdb1 on /data01 type xfs (rw,noatime,attr2,inode64,noquota)

Prerequisites:

1. Create a server bootstrap backup:
   1. From the NetWorker Management Console (NMC) or NetWorker Web User Interface (NWUI), perform a Server Protection backup job.
      1. If neither the NMC or NWUI is accessible, run the following command on the NVE: sudo nsrpolicy start -p "Server Protection" -w "Server backup"
      2. Monitor the backup session using: sudo nsrwatch
   2. Open an admin SSH session on the NVE and collect the bootstrap save set details: sudo mminfo -B
   3. If bootstrap email notifications are not configured, copy the mminfo output off of the NVE and save in a file. Email notifications can be configured by following: NetWorker: How To Configure Policy Email Notifications
2. Stop all running NetWorker server services:
   1. sudo nsr_shutdown
   2. sudo systemctl stop gst
   3. sudo systemctl stop nwui
3. Disable NetWorker services from starting during the next boot:
   1. sudo systemctl disable networker
   2. sudo systemctl disable gst
   3. sudo systemctl disable nwui
4. From VMware, shut down the NVE Virtual Machine (VM) and Increase the Hard Disk 2 from the VM's settings.

5. Create a VMware snapshot of the NVE, then power it up.

Process:

1. Once the VM has started, open an SSH session to the NVE VM as admin.
2. Switch to the root user by running: sudo su -
3. Validate that no NetWorker services are running: ps -ef | grep "nsr\|gst\|nwui"
4. Rescan the devices: echo 1 > /sys/block/sdb/device/rescan
5. Run fdisk against /dev/sdb this should show the current size and the size added in step 1:

nve:~ # fdisk -l /dev/sdb
GPT PMBR size mismatch (524287999 != 629145599) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
Disk /dev/sdb: 300 GiB, 322122547200 bytes, 629145600 sectors
Disk model: Virtual disk
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 3C1FF651-B360-4218-9106-DE80B690EA2C

Device     Start       End   Sectors  Size Type
/dev/sdb1   2048 524285951 524283904  250G Microsoft basic data

5. Increase the /data01 partition by typing: growpart /dev/sdb 1

nve:~ # growpart /dev/sdb 1
CHANGED: partition=1 start=2048 old: size=524283904 end=524285952 new: size=629143519 end=629145567

6. Verify the file system by typing: xfs_growfs -d /data01
7. The partition should now show the expanded size: df -Th | grep "/data01"

nve:~ # df -Th | grep "/data01"
/dev/sdb1                                   xfs       300G  4.8G  296G   2% /data01

8. Start NetWorker services: 
   1. systemctl start networker
   2. systemctl start gst
   3. systemctl start nwui
9. Reenable automatic startup for NetWorker services:
   1. systemctl enable networker
   2. systemctl enable gst
   3. systemctl enable nwui

Some additional steps that can be followed to reduce disk usage used by log files.

Jobsdb retention

The jobsdb is a NetWorker database which holds a record of policy completion statuses, it also determines how long the /nsr/logs/policy/ and /nsr/logs/recover logs are retained. The default window is 72 hours. After 72 hours have passed for a given job, its jobdsb entries are removed and any associated log files are deleted. The jobsdb retention can be seen in nsradmin:

nve:~ # nsradmin
NetWorker administration program.
Use the "help" command for help, "visual" for full-screen mode.
nsradmin> show Jobsdb retention in hours
nsradmin> print type: nsr
   Jobsdb retention in hours: 72;

nsradmin> . type: nsr
Current query set
nsradmin> update Jobsdb retention in hours: 72
   Jobsdb retention in hours: 72;

# NetWorker log files
/nsr/logs/daemon.log {
    rotate 5

    missingok
    compress
}

/nsr/logs/daemon.raw {

    delaycompress
}

• weekly this is the log rotation period; the logs are rotated every week. Other possible values are daily and monthly.
• rotate 5 indicates that only five rotated logs should be kept. The oldest file is removed on the subsequent run.
• missingok If the log file is missing, go on to the next one without issuing an error message.
• compress all rotated logs should be compressed.
• delaycompress can be used when some program cannot be told to close its logfile and thus might continue writing to the previous log file for some time
• Other options can be found in the logrotate man page. https://linux.die.net/man/8/logrotate
