Growing the Root Partition at End of Disk

last updated on Sept. 16, 2022

The way to grow the root partition on your Access Anywhere depends on what version of Access Anywhere was originally installed. To determine whether these instructions apply to your Access Anywhere, please consult this page carefully.

To begin, grow the disk space by expanding storage via the hypervisor or cloud platform to the first disk. Generally, the appliance will pick up the new disk space, but a reboot is recommended to ensure that the instance recognizes the increase.

After the reboot, log into the instance as smeconfiguser and become the root user: 

su -
Check the current size of the root partition. 
df -h
Sample Output: 
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda3        28G  3.3G   25G  12% /
devtmpfs        2.0G     0  2.0G   0% /dev
tmpfs           2.0G     0  2.0G   0% /dev/shm
tmpfs           2.0G  8.8M  2.0G   1% /run
tmpfs           2.0G     0  2.0G   0% /sys/fs/cgroup
/dev/vdb1        40G   80M   38G   1% /var/lib/mysql
/dev/vda1       509M   73M  436M  15% /boot
tmpfs           396M     0  396M   0% /run/user/5000
tmpfs           396M     0  396M   0% /run/user/5003
tmpfs           396M     0  396M   0% /run/user/0
tmpfs           396M     0  396M   0% /run/user/5001
In the example above the root partition has 25GB free and is mounted on /dev/vda3. Your system might have a different mount point such as /dev/sda3 or /dev/xvda3

Ensure the partition manager tools are installed: 

yum install cloud-utils-growpart parted -y

Grow the root partition (partition #3): 

growpart /dev/vda 3
Sample Output: 
CHANGED: partition=3 start=17827840 old: size=57669632 end=75497472 new: size=183498719 end=201326559
Expand the root filesystem: 
xfs_growfs /
Sample Output:

data blocks changed from 7208704 to 22937339
Check the amount of available space on / partition to confirm success: 
df -h
Sample Output:

/dev/vda3        88G  3.3G   85G   4% /
