Hi,
I am working on copying contents of a dir under a file system to a different file system. I am using rsync here, just to make to same. Below is what I am doing.
rsync -av /ora_dump/CTSPRD2 /ora_dump/NewCTSPRD2
I dont use compression because it's a local copy.
Problem I am finding is strange till now:
ohms# cd /ora_dump/CTSPRD2
ohms# du -sk *
1296 audit
1327 audit.old
712 babu
1629195 bdump <<<
19711 cdump
1 connect_report
0 exports
1 ksmsp_report
166080 monitor
1253699 perf
161078 udump
==========================
ohms# cd ../NewCTSPRD2
ohms# du -sk *
ohms# du -sk *
2420 audit
2506 audit.old
712 babu
4908252 bdump <<<
19710 cdump
0 connect_report
0 exports
0 ksmsp_report
0 lost+found
160624 monitor
1256534 perf
161148 udump
=============================
lvcreate -i 2 -I 64 -L 8192 -n vora_dump_ctsprd2 /dev/vgfs
==
newfs -F vxfs -o largefiles -b 2048 /dev/vgfs/rvora_dump_ctsprd2
====================================
I have tried chaning block factor to 8192/2048 etc. I can see the same usage difference,
ohms# bdf /ora_dump
Filesystem kbytes used avail %used Mounted on
/dev/vgfs/vora_dump
8192000 5445573 2574832 68% /ora_dump
ohms# bdf /ora_dump/NewCTSPRD2
Filesystem kbytes used avail %used Mounted on
/dev/vgfs/vora_dump_ctsprd2
8388608 6533104 1797578 78% /ora_dump/NewCTSPRD2
==============================================
I want to make it happen as ora_dump is common and I have seperate dir/s underneath it.
Anyone faced this or any suggestions..
Thanks and regards
Prashant
