daniel.amthor> Hello, the task at Hand is simple: Move 4.8 T daniel.amthor> Data from an AIX Box to a Linux Box. Good, you state what is the goal, which is more helpful than stating the means: daniel.amthor> I would like to format 5 extra Teras with jfs on daniel.amthor> the AIX Box, copy the data locally and then daniel.amthor> deatch the storage and move it to the new Linux daniel.amthor> Box. [ ... ] JFS for Linux is derived from JFS for OS/2, not JFS for AIX (which in light of the SCO case was an excellent idea), so you can do that between OS/2 and Linux but not AIX and Linux. However, if your goal is to transfer, as quickly as possible, and copying over network with something like RSYNC may be too slow, there is another conceivable workaround... Hoping that for a 4.8TB mass of data you are using RAID10 (as usual, nothing else would make much sense), say 40x250GB drives, you can use half of the drives as if they were tapes: * 'tar c' to those 20 drives (I would suggest treating each as an independent volume) and then you move the whole lot to Linux; * when you have the 20 drives with the data and the 20 empty drives under Linux, configure the 20 empty drives as a RAID0 of 20 RAID1s which are in single volume mode; * create a JFS filesystem on that RAID10, and 'tar x' the 20 'tar' files from the 20 data drives; * add the 20 data drives as the missing mirrors for the 20 RAID1 pairs. Very fast and fairly easy. Once can imagine variations, that do not require/exploit the degree of redundancy in a RAID10, but I won't elaborate as I don't think that would be wise. ------------------------------------------------------------------------- Take Surveys.
