Problem description:
Default Cloudcache data disk which 1 TB is full i.e 100%, or a larger deployment size is needed.
Filesystem: /dev/mapper/vg-lv
Mounted on : /mnt/data
Use%: 100%
Cause
Cloudcache store size is full, or a larger deployment size is needed.
Solution
As a best practice only allocate 90% of the total physical volume size in the Druva User interface to prevent the volume from getting 100% full.Example:1024 GB default volume, and the recommended volume would be approximately 920 GB.
Note: The default volume of the R3 CloudCache is dos formatted, and cannot be extended beyond 2 TB.
Steps to add an additional disk/s and extend the logical volume:
Shut down the CloudCache appliance VM.
Add a volume/s to the CloudCache VM of the desired size.
Note: If more than three vmdk disks are added then an additional disk controller should be added.
Power on the CloudCache, and logon to the system via SSH.
Stop the Druva-EnterpriseWorkloads.service
systemctl stop Druva-EnterpriseWorkloads.serviceRun the following command to identify the added volume:
fdisk -l | grep -i /dev/sd
* Example 400 GB disk:
Run the following command to initialize the volume:
* Be sure to replace the disk with the needed volume collected in step 4, and repeat for any additional disks to add to the volume group
pvcreate /dev/sdc
Now the volume group can be extended using the command below:
* Be sure to replace the disk with the needed volume collected in step 4.
vgextend vg /dev/sdc
Run the following command to extend the file system of the volume group:
lvextend -l +100%FREE /dev/mapper/vg-lv -rRun the either of the commands and verify the new size of the volume:
df -h – or – vgs
Start the Druva-EnterpriseWorkloads.service
systemctl start Druva-EnterpriseWorkloads.service
