AIX JFS file systems and 4k disksWARNING, PLEASE NOTE: AIX
JFS file systems are not supported on disks that have a sector size of 4
KB. So, if you try to restore a mksysb, that has JFS file systems in
rootvg, to a system with 4K disks, it will fail. You will see the
following message during the mksysb restore: "Disk block size of 4096 is
not supported for this filesystem". For example, you might be trying to
migrate (clone) an LPAR to a new POWER9 system that has 4K drives using
a mksysb image. You can workaround this by converting your rootvg file
systems from JFS to JFS2, using alt_disk_copy, then taking a mksysb to
restore to the 4K disks. http |
