- Section VII. Veritas InfoScale 4K sector device support solution
Migrating VxFS file system from 512-bytes sector size devices to 4K sector size devices
This section describes the procedure to migrate VxFS file system from 512 bytes to 4K sector size devices.
VxFS file systems on the existing 512-bytes sector devices might have been created with a file system block size of 1 KB or 2 KB, which is not supported on a 4K sector device. Hence, the traditional storage migration solutions, such as array level or volume level migration or replication may not work properly.
Starting With Veritas InfoScale 7.3 and later versions, you can migrate VxFS file system from 512-bytes sector size devices to 4K sector size devices using the standard file copy mechanism.
Note:
The standard file copy mechanism may not preserve certain file level attributes and allocation geometry.
Note:
Migration of VxFS file system from 512-bytes sector size to 4K sector size is supported only on Linux (RHEL, SLES, and supported RHEL compatible distributions) and Solaris 11 operating systems.
To migrate VxFS file system from 512-bytes sector size devices to 4K sector size devices:
- Mount 512 bytes and 4K VxFS file system
# mount -F vxfs /dev/vx/dsk/diskgroup/volume_512B /mnt1
# mount -F vxfs /dev/vx/dsk/diskgroup/volume_4K /mnt2
- Copy all the files from /mnt1 to /mnt2 manually
# cp -r /mnt1 /mnt2
- Unmount both the VxFS file system - 512 bytes and 4K
# umount /mnt1
# umount /mnt2
