We have old RHEL
machine version 7.2
And we prepare to install docker service on this server
The problem is that server's filesystem was created with ftype=0
parametre and docker requires ftype=1
One option of course is to format the disk with mkfs and create new file system with ftype=1
But we want to stay with the original OS and not format the disk
Second option is to perform the step as defined in the post - https://superuser.com/questions/1321926/recreating-an-xfs-file-system-with-ftype-1/1321963#1321963
But this steps are risky and required server to be down
We are searching for third alternative in order to implement the docker installation on rhel version 7.2 in spite ftype=0
Interesting direction could be for example by adding a new disk to the server and create XFS
file system, with ftype=1 , but we are not sure how to defined the docker installation on the additional disk (because this disk is actually without OS).
We will happy to get any other ideas out of the box.
