[Request to DELETE - Duplicate] NetWitness 12.4.0.0 Upgrade: Leapp Upgrade Failed

Issue

During the OS-Migration step, leapp upgrade phase fails with the below error in /var/log/leapp/leapp-upgrade.log:

 Error Summary
 
Disk Requirements:
 
At least XXX MB more space needed on the / filesystem.

Cause

If any XFS partitions have ftype set as 0, the overlay block sizes created by leapp would use extra space than the default size, causing the above error.
This is controlled using the LEAPP_OVL_SIZE variable and has a default value of 2048 MB. [Refer - Leapp 0.16.0 documentation]

To get the ftype value of a particular filesystem, run the below command:

 xfs_info /path/to/virtual/group | grep ftype
 
ex: xfs_info /dev/mapper/netwitness_vg00-root | grep ftype

Output:

 naming   =version 2              bsize=4096   ascii-ci=0, 
 ftype=0

Workaround

Resolution

Manually set the LEAPP_OVL_SIZE to 4096 MB

Steps:
1) Run the below command to incrase the LEAPP_OVL_SIZE to 4096 in the /usr/share/leapp-repository/repositories/system_upgrade/common/libraries/overlaygen.py file:

 sed -i 's/2048/4096/g' /usr/share/leapp-repository/repositories/system_upgrade/common/libraries/overlaygen.py

2) To confirm the changes, run the below command:

 egrep -i 4096 /usr/share/leapp-repository/repositories/system_upgrade/common/libraries/overlaygen.py
 

Output:

 env_size = os.getenv('LEAPP_OVL_SIZE', default='4096')
 
disk_size = 4096

3) Restart the upgrade

Notes

In case the issue persisted after the change, it means the / filesystem really doesn't have enough storage for the upgrade prechecks to complete. We can perform the below to move it to /var/netwitness and create a symbolic link for it in /var/lib:

 cd /var/lib
 
mv leapp/ /var/netwitness/
 
ln -s /var/netwitness/leapp
