Hello,
anyone with better knowledge of the OS5 kernel who can advise why is docker refusing to use any other storage driver than VFS?
This error pops out for overlay2, aufs, overlay and fuse-overlayfs
ERRO[2023-02-06T22:56:44.362544425+01:00] failed to mount overlay: no such device storage-driver=overlay2
In docker documentation (Use the OverlayFS storage driver | Docker Documentation) the only requirement for using this driver is kernel ver above 4.0
uname -r tells me 4.14.22.
So… Any idea why it is throwing errors? Unit is PR4100 btw.
Edit: Add docker info output:
root@MyCloudPR4100 proc # docker info
