Using vxdump

[schniela]

Good afternoon,
I am using vxdump to copy 1 file system to another, how long should/could this take? The system is an Itanium rx3600 running 11.23, the amount of data is 30G. The % finished has reached 1.08%. What might be the ending %? It has been running now for 3.5 hrs.
Thanks

That appears to be poor performance. Are you going over a network? A faster alternative if you are copying a filesystem to an LVOL/LUN/disk at least as large as the original is to use dd. Umount the source filesystem --- and the destination if mounted. Then dd if=/dev/rdsk/c1t5d2 of=/dev/rdsk/c2t6d3 bs=1024k. This will be the fastest possible copy because it is copying raw data. The filesystem meta-data is copied as well. Source the destination LVOL be larger then run extendfs on the filesystem after the fact and the filesystem will grow to fit the larger container.
