Hello, my customer has a following disk space question: on openvms 6.2-1h2 typing a "dir/siz=all/gran $1$dua8:[*...]*:*;*" command, he get this report: gran total 53 directories,16100 files,3337112/6511212 blocks from "show device/full $1$dua8:" he get following: cluster size=9 free blocks=1825668 total blocks=8378028 host name=hsd30 $1$dua8: is a mirrorset of 2xrz29b on hsd30 controller 2.5 fw. Consideration: customer has recently performed a backup/restore of disk; the cluster_size parameter is at minumun size. The Question : is possible to reduce the allocation space on disk ?

>$1$dua8: is a mirrorset of 2xrz29b on hsd30 controller 2.5 fw. HSD50 allows partitioning but HSD30 seems it doesn't. So replace them? ;-) How about RAID Software for OpenVMS for partitioning? Additional disks might be cheaper than this software, though... - Kazunori | |||||

hello, customer call me today and he has solved the problem.
He has detected that a program allocates disk space, but it doesn't
release the blocks unused.
Thank's Maurizio

$dir/sel=size=min=1000/size=all disk:[000000...]
would probibly have helped here

Just to beat that dead horse a little more...
>gran total 53 directories,16100 files,3337112/6511212 blocks
>cluster size=9 free blocks=1825668 total blocks=8378028 host name=hsd30
The absolute maximum loss due to the largish cluster size is
16,100 * 8 = 128,800 blocks. This is a far cry from those
missing 6,511,212 - 3,337,112 = 3,174,100 blocks.
Therefor, cluster size is NOT to blame and partitioning
would NOT have resolved this particular problem.
yes, Dan's command DIR/SIZE=ALL/SELE=SIZE=MINI=10000 would probably have
found the offending files IFF.. the customer had the patience to wait for
the result. A rather speedy, and highly recommended alternative to this is
the VMS freeware distributed tool DFU. DFU SEARC/SIZE=MIN=1000
Cheers,
Hein.
