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.
Once you have determined that the partition type is LVM, space can be added to the first disk via the hypervisor or cloud platform. 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/mapper/centos-root 14G 2.2G 12G 16% / devtmpfs 987M 0 987M 0% /dev tmpfs 997M 0 997M 0% /dev/shm tmpfs 997M 8.6M 989M 1% /run tmpfs 997M 0 997M 0% /sys/fs/cgroup /dev/mapper/centos-var 16G 626M 16G 4% /var /dev/sda1 509M 168M 342M 33% /boot tmpfs 200M 0 200M 0% /run/user/5003 tmpfs 200M 0 200M 0% /run/user/0 tmpfs 200M 0 200M 0% /run/user/5001 tmpfs 200M 0 200M 0% /run/user/5000
In the example above the root partition has 21GB free and is mounted on /dev/mapper/centos-root
Run pvs to see the LVM physical volume:
pvs
Sample Output:
PV VG Fmt Attr PSize PFree /dev/sda2 centos lvm2 a-- 34.00g 0
This appliance has 34GB allocated and 0 free. This is the base default. Please note the PV volume. In this case it’s /dev/sda2, however it may be different in your environment.
Now we will allocate the new disk space to this LVM physical volume. To do this we will need the tool “parted”, which may not be installed on the appliance. To install run:
yum install parted -y
Then run the command below, changing the green text to match the PV volume information obtained in the previous step. In our case our PV volume is /dev/sda2. Thus we will give the first part of the command the drive location which is /dev/sda and we will separate the partition number which is 2 for the resizepart flag.
parted -s /dev/sda resizepart 2 100% partprobe pvresize /dev/sda2
Sample Output:
Physical volume "/dev/sda2" changed 1 physical volume(s) resized / 0 physical volume(s) not resized
Now our LVM physical volume should show more free space:
pvs
Sample Output:
PV VG Fmt Attr PSize PFree /dev/sda2 centos lvm2 a-- 59.50g 25.50g
To allocate all of the new space to the root partition run the following command:
lvextend -l +100%FREE /dev/centos/root
Sample Output:
Size of logical volume centos/root changed from 14.00 GiB (3584 extents) to 39.50 GiB (10111 extents). Logical volume root successfully resized.
NOTE: If only some of the space is desired for root and the rest should be allocated to the mysql partition the below examples can be used.
Give just the amount of space desired to grow root partition by:
lvextend -L+10G /dev/centos/root
Sample Output:
Size of logical volume centos/root changed from 14.00 GiB (3584 extents) to 15.00 GiB (10111 extents). Logical volume root successfully resized.
To grow the mysql partition by some amount of space:
lvextend -L+10G /dev/centos/var
Sample Output:
Size of logical volume centos/var changed from 16.00 GiB (3584 extents) to 26.00 GiB (10111 extents). Logical volume root successfully resized.
Once the partition is grown check the new size:
lvs
Sample Output:
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert root centos -wi-ao---- 39.50g swap centos -wi-ao---- 4.00g var centos -wi-ao---- 16.00g
Finally grow the root filesystem into the partition space:
xfs_growfs /
Sample Output:
meta-data=/dev/mapper/centos-root isize=256 agcount=4, agsize=917504 blks
= sectsz=512 attr=2, projid32bit=1
= crc=0 finobt=0
data = bsize=4096 blocks=3670016, imaxpct=25

naming =version 2 bsize=4096 ascii-ci=0 ftype=0
log =internal bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
data blocks changed from 3670016 to 10353664
Check the amount of available space on / partition to confirm success:
df -h
Sample Output:
